Kia Telluride 2021

My 2021 Kia Telluride (approximately 82,000 miles) suffered catastrophic engine failure caused by excessive and abnormal oil consumption. The engine consumed oil at a dangerous rate with no warning lights or dashboard indicators of any kind. The only symptom prior to failure was an unusual engine noise. There was no opportunity to take corrective action before the engine failed completely. This failure occurred while I was driving with my children in the vehicle, creating a serious and immediate safety risk. A sudden engine failure at highway or city speeds — with no prior warning — presents the risk of loss of vehicle control, inability to accelerate out of traffic, and potential collision. The failure has been confirmed by two independent service centers: Vanguard Kia in Arlington, Texas and Christian Brothers Automotive. Both confirmed engine failure. The vehicle and failed components are available for inspection upon request. Kia America has declined to provide warranty assistance or goodwill repair coverage despite this being a widely reported issue among 2021 Telluride owners with the same Lambda II V6 engine. No recall has been issued. Repair cost is approximately $11,000. I am still carrying a loan on this vehicle. I am requesting NHTSA investigate this as a systemic safety defect and consider a mandatory recall.

021 KIA Telluride, February 13, 2021. Temperatures are single digits or below and got worse as the week went on. Started the engine and a loud squeal or whistling noise came from the top of the engine. Last about 30 seconds then slowly stops. Engine also starts to sound like it has more power once noise stops. Been going on for the last 8 days. Belts and pulleys seem to be working fine and cannot see any issues. Sound like it is coming from under the engine cover but do not want to remove cover cause too cold and do not want to jeopardize warranty stipulations. Contacted midwest KIA in wichita, kansas. Sent them a video and they think it is a vacuum leak of some kind. Midwest KIA said they cannot report it to KIA until they can see the car but we are 2 hours away and cannot get off work to take it and need our car for work. I own a mortuary and have funerals and my wife is a teacher and cannot get substitutes do to covid. I said based on my research it sounds like intake manifold. On the KIA forums, many people experiencing these very cold temps are experiencing the same noise and encouraged me to report the issue. I feel it is cold related and hope KIA looks into this problem. This only happens when the car has been sitting for several hours. If we use it off and on without sitting too long the noise does not happen. Car runs great once the noise stops.

My wife had placed our two children in the car in their car seats. She attempted to start the vehicle by pressing the brake and the starter button. Though all the dome lights and other normal electrical items were on at the time, as soon as she attempted to start the car, it instantly went dead. There was no power to anything, and all the interior dome lights did not work. No matter how often she attempted, she could not start the vehicle, even with accessory mode. It was almost as if the battery had been suddenly removed from the vehicle. At no point was the car moved outside of park. My wife removed our two kids from the vehicle, and shortly after, they were secured in our other vehicle; without my wife being in the Telluride, the car turned on itself. All interior lights were on, and the car was functional. She found that while the radio was on, the HVAC that had been on was now off. In addition, the fuel performance reset to zero. She turned off the vehicle, and we could not reproduce the issue. From a safety perspective, this was very unnerving as it involved our children in our car, but also that the car started on its own after five minutes. If we were not at home and the car could have been running in the garage without our involvement. All regular maintenance and satisfaction of recalls had been completed by a Kia-authorized dealership before this event.

I drove my brand new Telluride off the lot with approximately 12 miles on it. About a month after having it I noticed the following: when entering a highway from about 20-25 MPH, the vehicle would not gradually accelerate allowing me to enter the highway. As I continue to press the accelerator pedal the rpms would eventually jump up and the vehicle would launch itself forward. Reaching 5000-6000 rpms. When I let off the accelerator the engine would downshift similar to a manual transmission and would jerk as it changed gears and the rpms decrease. Additionally, when creeping in traffic I notice jerky and hesitation from the engine/transmission. This is quite dangerous as one time it almost launched me into the back of the vehicle in front of me. Merging onto a highway is also quite dangerous as I am not confident the vehicle will accelerate when I attempt to merge. I have taken it to a dealership and had the technician drive it and he concurred that there is a problem. The dealership has tried working with the manufacturer but to no avail after 3 months. Now the dealership won't even call me back. The dealership, via the recommendation of the manufacturer, has reset "adaptive values" at least 3 times, but that did not fix the problem. There are no warning lights or messages of a problem. While quite noticeable, this problem is even more noticeable when it is in Sport mode.

I was pulling out of a parking lot going about 3 mph. There were no other vehicles around and the windshield cracked right in front of me. I called my insurance and explained to them the strange event that just took place, and they said that it would be a deductable of $500.00 or around $1000.00. Reasearch has proven that quote. The next day I went out to the car to start it up so the kids wouldn't be so hot. I watched the 6 inch crack from the day before, turn into a a 3.5 foot crack. Kia dealer says it's a rock chip so outside of warrenty. There is absolutly no way that a rock hit my windshield with no other cars around, and me going 3 MPH. I contacted Kia customer service, and was told that the dealer said it was a rock chip, therefore it was out of warrenty. At this point I am so terrifed to put my kids in that car, because look what happened when going at very sluggish speeds. On top of all of that, the replacment windshields are also prone to cracking, so all of us Telluride owners are between a rock, and a hard place. Someone, please look into this and force Kia to make it right to all of us who just bought a new family vehicle. I do have pictures of the windshield, however I cant upload them due to the very low upload space on this NHTSA website. Please reach out with an email and ill get them to you ASAP.

There is an ongoing problem with the NIVOMAT self-leveling shocks on every model year of this vehicle. The problem occurs at nearly every speed but is more noticeable at lower speeds (35mph or less) while going over uneven terrain or hitting small bumps. The vehicle produces a clunking noise from the rear of the vehicle and there is no cushioning or rebounding from going over the bump or uneven terrain. Instead, there is more of a jolting knock when hitting small bumps and a constant bouncing around/floating feeling while driving over uneven terrain. This is dangerous because passengers and cargo in the vehicle gets bounced around and the vehicle gets harder to control especially at higher speeds. Many of these shocks are failing early in the life of the vehicle. Mine is at 27K miles, however I believe the problem started before and probably closer to 18-20K miles. Kia knows about this issue but has failed to come up with a reliable solution. This is four model years now with the same issue. Kia has released TSB after TSB on this, only replacing certain parts of the shock (isolators, etc.). However, there are still reports of replacement parts and even new full shock assemblies failing around the same amount of milage. It would be great if a wider recall can be issued to address this ongoing problem that seems to affect every model year so hopefully Kia can find a more reliable, quality part to replace the consistently failing part.

My 2021 Kia Telluride has developed progressively worsening engine problems without any warning lights ever appearing that may present a serious safety concern. Approximately two months ago, the vehicle began experiencing significant engine shaking and rocking. Maintenance and repairs were performed, and the symptoms temporarily improved. The engine symptoms later returned. The vehicle began making a noticeable ticking noise that progressively became much louder and occurred both while idling and during acceleration. The vehicle subsequently shut off after being driven to an independent mechanic. Multiple warning/diagnostic alerts appeared, and the vehicle would not remain running when restarted. The mechanic checked the engine oil and found it essentially empty. Approximately 4½ quarts of oil were added. The ticking noise continued despite the addition of oil. Later that same day, the engine developed a pronounced knocking noise that continued while driving. There was also a hot smell, and I had noticed discolored smoke coming from the exhaust. The vehicle is currently parked and is available for inspection. I have stopped driving it because I am concerned about an engine failure and the possibility of the vehicle shutting off or losing power while being operated. The vehicle has been maintained and I have documentation of its maintenance and repair history. The underlying cause of the severe oil loss and engine symptoms has not been determined.

On September 4, 2026, my son was driving our 2021 Kia Telluride on the highway at approximately 70 mph with cruise control engaged when the vehicle suddenly began making a clicking noise, followed by a catastrophic engine failure. We observed no oil-pressure warning or other advance dashboard warning before the failure. The sudden failure at highway speed created a significant safety risk. I am the original owner. The vehicle had approximately 115,000 miles at the time of failure. Its most recent oil change was performed on June 4, 2026, at 112,613 miles, approximately 2,400 miles before the incident. The servicing Kia dealership reported that the engine had a hole in it and essentially no oil remaining. The oil filter and drain plug were in place, and the dealership reported no external oil leak that explained the missing oil. An oil-filter-housing leak had previously been repaired in January 2026. The cause of the oil loss and engine failure has not been conclusively established. I am concerned about possible excessive internal oil consumption and the absence of an advance warning before catastrophic failure. I request that NHTSA investigate whether this condition affects other Tellurides and creates a risk of sudden engine failure or loss of propulsion at highway speed. Kia denied my initial request for goodwill repair assistance. The case has been escalated, but remains unresolved. The vehicle and failed engine are available for inspection through the servicing dealership.

NHTSA Vehicle Safety Complaint – 2021 Kia Telluride - VIN: [XXX] I am filing a safety complaint regarding my 2021 Kia Telluride. I purchased the vehicle on XXX, with approximately 124,000 miles. An oil and filter change was performed shortly before the sale. After about 2,000 miles/126K, the vehicle suddenly lost power and stopped. It was towed to a repair shop, where technicians found the engine oil level was extremely low or empty, despite no low-oil warning light appearing. The oil was serviced, and the vehicle was returned to operation. About 3,000/129K miles later, the vehicle again lost power and stopped in Ardmore TX. It was road side mobile mechanic found little to no oil and he refill the oil. After 100 miles/129.1K again same problem engine stopped and no oil. was towed to the same shop, where technicians found little to no oil and diagnosed severe engine damage requiring engine replacement. Mechanic informed there was no oil leak from the engine however, excessive oil burning in engine causing this issue. My concern is safety. On all three occasions, the vehicle lost power on the freeway at night while my family with two kids was in the vehicle. I believe excessive oil consumption and the lack of a warning before engine failure may represent a safety defect. I request that NHTSA investigate this issue and require Kia to review the vehicle’s engine design and warning systems.

Since November 2023, the car's engine has been burning oil. There are no leaks in the driveway. On January 8th (87,000 miles), I took the Kia Telluride for service at Mission Viejo Kia for a Check Engine light. They said the car had low oil and indicated that the cause was a leaking oil housing. They completed an oil change and added new oil. On February 19th (90,000 miles), the AC drain was clogged and water was entering the passenger side inside the vehicle. In addition to this fix, Mission Viejo Kia noted that the oil level was down to 1/2 quart. This was only 3000 miles since the last oil change. On April 6th (95,000) completed another oil change at Ramona Tire, where I was getting new brakes. They did note very low oil. June 24th (96,600 miles), the Telluride started rattling and stalling at lights. Upon inspection, Mission Viejo Kia determined it was due to low oil again. July 9th (98,000 miles) I inspected the oil dipstick and saw barely any oil. I took it to Mission Viejo Kia and it is currently awaiting direction from Kia Corporate for the next steps. This was only 2000 miles after the most recent oil change. There was no oil leaking in the driveway. My research has shown that Kia Tellurides and other Kia/Hyundia are experiencing rapid oil consumption. This eventually could lead to engine failure and catalytic converter failure. Class action suits have been filed and dismissed recently. My 100,000 mile warranty is coming up. This complaint is to document the issues I have been experiencing for any possible future action.

I purchased this 2021 Kia Telluride new and have had it routinely serviced and maintained by authorized Kia dealerships. At approximately 60,000–80,000 miles, the engine began consuming excessive oil. I reported the condition to the Kia dealer at approximately 80,000 miles, while the vehicle was still within Kia's 10-year/100,000-mile powertrain warranty. The dealer initially recommended a tune-up, but the oil consumption continued. During a later visit, the dealer identified an issue involving the OEM oil-filter housing and replaced the affected component. Despite this repair and continued maintenance, oil consumption progressively worsened. The vehicle now has approximately 160,000 miles and requires approximately one pint of oil every 2–3 weeks. The current diagnosis indicates potential internal engine damage, including cylinder-wall scoring that may allow oil to bypass the piston rings and burn in the combustion chambers. I have been advised the engine may require replacement at an estimated cost of approximately $13,000. My primary concern is that this condition began and was reported to Kia while the vehicle was still under the powertrain warranty, but the repairs did not correct it. Continued excessive oil consumption and internal engine damage create a safety concern because they could result in low oil pressure, engine seizure, stalling, or sudden loss of propulsion while driving. The vehicle is available for inspection, and its maintenance history, prior complaints, dealer repairs, and current condition are documented through Kia dealership service records.

While at a red light after exiting the highway, the vehicle lost all power and functionality. The car was in drive, and the brake was pressed in. No buttons had been pressed to shut down the vehicle. I had no power and no ability to restart the vehicle. I placed the vehicle into park and attempted to turn on my hazard lights. Unfortunately, there was no response from the vehicle, and though I was interrupting traffic, I could not provide any visual indicators to oncoming traffic. After moving the vehicle into park, I was unable to move the car into neutral. After approximately five minutes, without the brake being pressed or any button is pressed, the vehicle turned on its own. I was able to move the car into drive and continue to function as expected. Prior to this, I had used the vehicle to drop off my kids at daycare (which required turning on the vehicle, driving, and turning off the vehicle). This event occurred roughly 40 minutes after a mix of highway and city driving. From a safety perspective, this was very concerning as I had no way to indicate to other drivers that my car was not driveable. Fortunately my children were no longer in the car. I was very concerned that not only the car lost all power and functionality, but was more concerned that the car started on its own. I was also concerned that if I had not moved the car to park and somehow it turned back on if left in drive what potential damage could have been done to me, another vehicle and potential injury 30K service and all recalls had been satisfied prior to this by an authorized Kia dealership.

The vehicle started vibrating within a month of the purchase at speeds between 60-80. Several trips to KIA with KIA tech line and they deny the vehicle has an issue. They said the vibration measured with a picoscope was within the normal Range. After fighting with KIA consumers, I took it to a driveshaft specialist for an independent diagnosis. The findings from the driveshaft specialist were quite alarming and it's obvious KIA is trying to hide the problem and forcing customers with the same problem to live with it. Driveshaft specialist told me this problem would get worse and affect other areas of the vehicle. I have been following a KIA forum and they are literally hundreds of Telluride awd's with the same problem. Yesterday I traded my vehicle off at a $6K loss so I did not have to deal with the headaches and keep fighting KIA. This is not right to consumers and has been going on since their 2020 AWD Telluride. It appears to be a manufacturing design flaw. I filed a complaint with the Texas attorney general #CGS-266219 in October. I have filed numerous complaints with KIA consumer assistance case #13767404. They offered me $2500 and wanted me to sign off on the complaint. I have not signed anything or received any monies. I just lost $6,000 because of these people so $2500 is not covering my loss. I have recently recovered from surgery, chemo, and radiation and do not have the strength to fight this giant. They need to be held accountable. There is a KIA forum on vibration where there are literally several hundred people with this problem. Please help us hold them accountable.

I own a 2021 Kia Telluride with approximately 111,000 miles. I initially brought the vehicle to a Kia dealership for an oil consumption issue and engine noise. The dealership diagnosed and repaired a timing chain and tensioner issue, stating the vehicle was “working properly” upon return. After picking up the vehicle, I immediately began experiencing electrical warning lights, including the battery warning light and system alerts (blind spot and general warning indicators). I returned to the dealership, where they performed diagnostic testing and indicated a potential alternator issue, but stated it was in a “borderline” range and that the vehicle was safe to drive. Shortly after leaving the dealership, while driving with my family in the vehicle, the electrical system began to fail. Multiple warning lights illuminated, and the vehicle lost electrical function while in motion. The vehicle ultimately became completely inoperable and shut down in a parking lot, creating a serious safety concern. Prior to the dealership visit and repairs, the vehicle had no history of electrical issues, warning lights, or charging system problems. The dealership later acknowledged that the alternator issue was not present when the vehicle was initially brought in. I am submitting this complaint due to the sudden and complete electrical system failure while driving, which posed a significant safety risk. The progression from no prior symptoms to total failure immediately following dealership service and diagnosis raises concerns about vehicle reliability and potential safety defects related to the charging system.

After warranty work was performed on my Kia Telluride at an authorized Kia dealership, I discovered that the rear driver-side seatbelt had not been bolted back down. It was completely loose and hanging under the seat. This means my family could have been driving with no seatbelt protection at all. This is a serious safety failure and clear negligence. A seatbelt is one of the most basic, life-saving components in any vehicle. For a dealership to return a car to a customer without confirming all seatbelts are installed correctly shows a complete breakdown in safety inspection and quality control. When I contacted the dealership, I received no apology, explanation, or acknowledgment of responsibility. No one followed up or offered to inspect the vehicle. I also contacted Kia America Customer Relations, but I have not received any response. If such a fundamental safety step can be missed, I am extremely concerned about what other oversights may occur during Kia service work nationwide. This situation should be formally investigated by the NHTSA. I’m requesting a full investigation into Kia’s service procedures, technician training, and inspection protocols to ensure that no other vehicles are returned to customers in unsafe condition. Please treat this as a formal safety complaint. A loose seatbelt is not a minor error, it’s life-threatening negligence. I want this fully investigated and documented under my VIN, with confirmation of corrective action. My family’s safety, and that of other Kia owners, depends on it.

I believe my engine to be defective and Commonwealth Kia to be neglegent in finding the defect dispite having been tasked to repair an issue while my car was under warranty. I first mentioned the problem on the XXX visit at $85,000 miles. Asked them to check the filters. Mentioned again at the XXX visit at 92,000 there is not documentation of the complaints on either of these visits but it does say ont eh XXX visit that the car "STILL LACKS POWER..." indicating that there have been previous discussions about the issue. The car was at 99,000+ miles at the XXX visit (still under warranty) I returned on XXX and XXX and was told on 1/20 that they FINALLY found the problem and that I would have to pay to have the entire engine replaced. I have since done some research and the issues that I am having are very similar to the Class Action Suit against Kia and the THETA II engine. [XXX] I have also seen on multilple owners boards on social media and in reports found on the internet that 2020-2023 Kia Tellurides have been having the same issues as THETA II engine models. [XXX] I find it difficult to believe Commonwealth Kia Service have not heard similar complaints nor have the ability to diagnose the problem on the first or second mention of the problem (which was while the car was still under warranty) I have called Kia USA who can not help me due to the fact that I am the second owner. The car was sold to me as "Certified Pre-Owned" by Kia. I believe Commonwealth Kia willfully misdiagnosed my problems so as to push the replacement cost to me and not the warranty INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1) What component or system failed or malfunctioned, and is it available for inspection upon request? The panoramic sunroof assembly — specifically the sunroof panel and its track/mechanism — failed. The sunroof panel came off its track and damaged related components (e.g., guide rails/wind deflector arms). The damaged sunroof and broken parts are available for inspection upon request. 2) How was your safety or the safety of others put at risk? The sunroof panel dislodged unexpectedly during normal use. This could have caused objects or glass to fall into the cabin or onto the roadway, presenting a risk of injury to occupants or other road users. Sudden failure of the sunroof mechanism also poses a distraction while driving. 3) Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The dealership/service center inspected the vehicle and confirmed the sunroof panel was off its track and broken. (If the dealer refused to acknowledge it as a defect, state: “The dealership inspected the failure but did not classify it as a warranty defect.”) 4) Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle/sunroof was inspected by an authorized Kia dealership service department. (If applicable: “Insurance representatives were not involved.” / “Kia corporate has not inspected the vehicle.”) 5) Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps or dashboard messages prior to the sunroof failure. There were no abnormal noises or operational symptoms immediately before the sunroof panel disengaged from its track.

After owning this Telluride for a year the engine started stalling. I took it into the nearest Oil change company, and they informed me that the oil was completely out and dry. I always stay up to date with my oil changes, so this was a huge shock. There was no light that ever came on stating an oil concern and there was no light that came on even when the engine stalled. This company sent me directly to Kia stating they have seen this several times with this vehicle and they have oil consumption issues. I went to Kia and they had me do the oil consumption test. When completed they stated I was within the "standard" oil consumption levels. I asked why the car didn't even have an oil light or engine light come on as a warning and they had no answers for me. Had a light come on I would've taken it to be looked at prior to having the engine stall on me which was a major safety issue. Fast forward, I ended up and purchased another car and gave the Telluride to my husband. I drive a lot for work and he doesn't, so it made more sense to help with the oil. We are now having to put at least 3 quarts of oil in it in between oil changes. And he has still experienced the engine puttering. Both times with our kids in the car, steering becomes difficult and he has to pull off the road. Once he turns it off and restarts, it seems to be fine. Another mechanic told us that they anticipate a recall to come out with the 2021 Telluride soon since they have already recalled previous years for the same issues. It is absurd to have to put in 3 quarts of oil in between oil changes. The fact that no warning lights have ever come on is safety concern. The car randomly stalling is a safety concern. Kia needs to do something about this before someone gets injured.

I am reporting a serious and ongoing electrical and transmission issue with my 2021 Kia Telluride (VIN: [XXX] ). The problem began under 20,000 miles and has continued intermittently for years, progressively worsening. My vehicle is currently at ~99,600 miles and under extended warranty. The key safety concerns include: Transmission Lockout: The vehicle intermittently becomes stuck in Park and will not shift, even with the brake depressed. No-Start Condition: The vehicle will randomly become completely unresponsive—no dash lights, no infotainment, and no engine start. Electrical System Failure While Driving: Multiple safety systems fail mid-drive, including: Loss of power steering and air conditioning Random activation of ESC, TPMS, Collision Assist, Blind Spot, and Parking Brake warnings Infotainment screen turns off while in motion Component Failures Due to Electrical Shorts: Both the radio and the backup camera were diagnosed with shorts and had to be replaced under warranty. Brake Lockout Post-Shutdown: The brake pedal becomes very firm and the vehicle will not restart until hours later. Most concerning, my wife and children have been left stranded in the disabled vehicle on multiple occasions due to these issues. The car has been in the shop several times — around 50,000 and 80,000 miles — but no permanent resolution has been found. This is a clear and escalating safety hazard. The failures affect critical systems while driving and leave the vehicle unpredictably disabled. Kia has been made aware and an escalation is underway, but I am filing this report to ensure the NHTSA is aware of the pattern and potential danger these failures pose to others.

What component or system failed or malfunctioned, and is it available for inspection upon request? While driving the vehicle, it intermittently hesitated during acceleration until there was a very loud popping and banging noise, it was sudden and very loud. We experienced a complete and sudden loss of power. The car then proceeded to send off nearly every alert on the dash, and threw a code which was P061B. The engine blew out, the oil pan was fractured by ejected connecting rod (visible from underside). How was your safety or the safety of others put at risk? When the engine blew out in the fast lane, our physical safety was at risk due to the immediate loss of control and power, the inability to merge, and stopping next to the center divider in a high-traffic area. In the car were my wife and 3 kids. Psychologically, the fear and panic of our family being stuck, the stress of making quick decisions, and the vulnerability of being exposed to fast-moving vehicles added significant pressure. In that moment, our family was left utterly helpless, fearing for our lives in the face of an overwhelming, life-threatening crisis. Has the problem been reproduced or confirmed by a dealer or independent service center? The car is currently at a Kia service center in Santa Rosa, Ca. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? UNKNOWN, the vehicle is at the service center in Santa Rosa, Ca. The vehicle was also inspected by a local mobile mechanic. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no alerts, warning lamps, or messages, the car did experience some hesitation during acceleration but it was intermittent.

Unfortunately, beginning in June 2025, I experienced a serious engine problem. While driving, the vehicle began sputtering and stalled twice in traffic. I immediately brought it to the dealer, where I was told the engine had no oil, despite no prior warning of abnormal oil loss (no engine warning lights and no leaks). The service department added oil and initiated an Oil Consumption test. On October 4, 2025, the same problem occurred again. While driving, the Telluride began sputtering again, and the dealer again determined that the engine had no oil. I was charged for another oil change and instructed to complete another Oil Consumption test. During this process, the maintenance supervisor acknowledged that excessive oil consumption was a known and serious issue affecting Kia Tellurides and other models, and explained that engine replacement was the appropriate solution. I also observed another Telluride at the dealership undergoing the same type of engine repair. After completing the required testing, the dealer ultimately installed a rebuilt engine in my vehicle to address the excessive oil consumption problem with the original engine. I am now back in the same situation. On September 8, 2026, less than one year after the rebuilt engine was installed, my Telluride once again began sputtering while I was driving. I brought the vehicle to back to the dealer on on September 9, 2026. The service personnel again told me there was no oil in the vehicle, despite it being well within its recommended oil-change interval. More importantly, I was informed that the rebuilt engine currently installed in my vehicle is suspected of having the same excessive oil-consumption problem as the original engine. After following the instructions on yet another engine recheck and Oil Consumption test, I 've been told that the engine is burning oil at an exponential rate.

As I was driving down the interstate heading to a doctor’s appointment the unexpected happened with my Kia Telluride. My Telluride is a 2021 and only had roughly 37,000 miles on it, and I believe it is important to notate that I’ve never had any issues with this car since purchasing it. However, on this particular day, as I was driving down the interstate the entire window located on the drivers side at the rear back seat shattered. I thought someone may have hit me but as I pulled over there was no evidence of any damage besides the window shattering. There was no sign of rocks, material, or anything that would have caused the shatter. I called the police prior to examining the vehicle who stated that the window appeared to have shattered at its own discretion and therefore they could not file a police report. I did however pay to have the window replaced, and pay to have glass removed from every inch of my car as the glass shattered everywhere. The biggest concern was that the chunks of glass/shatters were mostly in my one year old daughters car seat. The police stated that if she was in her car seat at the time of the window “explosion” she would have been severely injured or even possibly death due to the large amount of glass. As a driver of the vehicle, I myself had pieces of glass fly into my arms while I was driving, but I thank God my Duaghter was not in the car with me that day. Not only is this harmful to the driver or passengers but also harmful to other drivers as it could have caused an accident. I am still nervous to this day about having my kids in my telluride as I never know if the window may shatter. This is a worry I never had before and believe this is worth investigating. I never had any signs, warning lights, or any warning of this event, as I was simply driving, heard a loud boom and realized the window had shattered and glass was everywhere.

I am submitting this complaint regarding my 2021 Kia Telluride experiencing repeated and dangerous electronic system failures while driving. Kia of East Syracuse (NY) diagnosed the issue as related to the backup camera assembly and communication/network failures. While driving, the vehicle experienced loss of power steering assist, instrument cluster failure, speedometer malfunction, incorrect gear indication, backup camera activation while driving forward, blind spot warnings activating incorrectly, flashing/blank temperature display, and multiple driver assistance system failures. The speedometer displayed 0 mph while the vehicle was in motion and later displayed approximately 40 mph while stopped at a traffic light. The vehicle also became stuck in reverse while backing out of my driveway and would not shift properly, leaving the vehicle stopped in the roadway. Multiple safety systems malfunctioned simultaneously, including Blind Spot Collision Avoidance Assist, Lane Following Assist, Rear Cross Traffic Collision Avoidance Assist, Smart Cruise Control, Parking Distance Warning, and Forward Collision Warning systems. The dealership documented multiple fault codes and stated the dashboard lit up “like a Christmas tree” while the instrument cluster stopped functioning entirely. These failures create a serious safety risk because critical driving information and driver assistance systems become unreliable or inoperative while the vehicle is moving. The failures occur unexpectedly and without warning. Photos and video evidence have been retained, including video of the backup camera activating while driving forward and the speedometer malfunctioning while the vehicle was in motion. I am asking NHTSA investigate these failures as a potential safety defect involving the camera system, instrument cluster communication systems, and CAN network communication failures in the Kia Telluride.

Component/System Failure: The engine and lubrication system appear to be malfunctioning. The vehicle has repeatedly experienced sudden engine shutdown while stopped at traffic lights and during low-speed operation. The dealership has identified oil leakage involving the oil pan and oil filter housing and has indicated there may be an internal oil leak within the engine. The vehicle is available for inspection upon request. Safety Risk: When the engine shuts off unexpectedly, the vehicle loses propulsion in active traffic. This creates a risk of rear-end collision and prevents immediate maneuvering out of traffic flow. The loss of engine power while stopped or moving at low speeds presents a serious safety hazard to myself and surrounding drivers. I am concerned that the suspected internal oil issue may lead to catastrophic engine failure while driving. Dealer Confirmation / Reproduction: The issue has been reported to the dealership multiple times beginning in January 2025. The vehicle has undergone multiple inspections and repair attempts, including partial fuel injector replacement, battery replacement, and an oil consumption test. The dealership has acknowledged oil leakage and has stated that replacing the oil pan gasket and oil filter housing may not resolve the suspected internal oil leak. The defect has not been permanently corrected. Inspection by Manufacturer or Others: The vehicle has been inspected multiple times by the dealership. The matter has been escalated to Kia Corporate for review. No police or insurance inspections have occurred, as no collision has yet resulted from the stalling events. Warning Lamps / Symptoms: During each stall event, the check engine light illuminates along with multiple dashboard warning lights. The stalling first began in January 2025. Oil-related concerns and possible oil loss were reported during prior service visits. The condition continues despite repair attempts.

In December of 2025 at approximately 95,000 my 2021 Kia Telluride (VIN [XXX] ) showed the oil level was about two quarts low. My car has had regular maintenance including oil changes at Santa Fe Kia. At the next oil change appointment in March, I pointed out the oil consumption concern. At that point Kia recommended an oil consumption test be performed. The car had 96,700 miles at that point. At 97,700 Kia indicated that the oil level was fine. At 99,600 I checked the oil and discovered it was more than two quarts low. I called Santa Fe Kia to address the issue and they indicated that a quart every 1,000 miles is within Kia standards and recommended another oil consumption test which would take me over the 100,000 warranty. I called Kia customer care to address the issue. A case was opened, but they kept referring me back to the dealership to be dealt with. After researching the issue myself, I presented the well known and documented oil consumption issue amongst Kia consumers to include PCV valve and piston ring issues. I have an appointment scheduled for 4/16/26, but I am being told that I will be liable for the cost of the PCV valve replacement, compression test and oil leak test which are all known issues related to the problem. Santa Fe Kia's service manager is ignoring my request to submit an engine warranty claim citing that they didn't find a problem outside of Kia's acceptable oil consumption and Kia's customer care refuses to open a claim and keeps referring me back to the dealership. I will be at approximately 99,850 when I arrive at my appointment on 4/16/26. I am concerned that the engine has a major issue and will be told that my warranty is over by the time the issue can be determine and resolved. I am also concerned that there has already been engine damage done without noticing the high oil consumption.

On or about December 2024, we noticed a hesitation or sputtering in the performance of our Kia. I contacted Ancira Kia who reviewed the vehicle, which displayed no warning lights. Since they couldn’t duplicate the issue, nothing could be done. On or about [XXX], the vehicle’s cooling fan engaged on its own while parked in the garage and revved up extremely high. This was the second time this had happened. Ancira Kia couldn’t duplicate the problem although they mentioned another customer was experiencing the same problem. A few days later, I was advised to bring the vehicle in for a sensor replacement. So far, the problem hasn’t recurred but I won’t know if it’s fixed until it never happens again. On [XXX], while traveling from Del Rio to San Antonio, TX, we stopped at a rest area. There were no warning lights visible and no performance issues noted until this time. When we started the vehicle to leave, we noticed a slight knocking that went away when we put the vehicle in drive. After our next stop, we noticed the knocking noise again when we started the vehicle and the noise dissipate when we drove. After the next stop the noise appeared to be louder so we decided to stop for lunch and let the vehicle cool down so we could check the oil. When we checked the oil, we saw there was no oil marking the dip stick. I took the vehicle to Ancira Kia who also found no oil marking the dip stick. The engine was ruined and needed to be replaced. None of the Telluride’s warning systems illuminated. No check engine or oil pressure lights lit up. This is a catastrophic failure of the Telluride which placed my husband and I in severe danger. We could have been injured and possibly killed had the engine seized while we traveled on the highway between Del Rio and San Antonio, Texas (150 miles). My vehicle is meticulously maintained at Ancira Kia. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

CATASTROPHIC FAILURE TIMELINE (13 DAYS) XXX: Delivery taken at 105,439 miles.XXX: My boyfriend noticed a cloud of smoke from exhaust as I pressed the accelerator pedal to leave the parking lot. I didn't notice because it was almost dark outside when leaving. He didn't notice again so he didn't stop me and told me when we got home. XXX (Day 12): Check Engine Light (CEL) on. Dipstick found dry. 2 quarts of oil purchased and added. Which brought the level right above the L line. Sent texts to both salesmen (Freedom and Driveway). Went to work in [XXX]. XXX (Day 13): Got home with Odometer: 106,974. Plugged Code reader into the vehicle and got Code P0597 logged at 1:04 AM. Tried both salesmen again through texts, email and or call. Have yet to get a reply from either. XXX posted review updates on both of my previous posted reviews for Freedom and Driveway. Received my first response from the Driveway review team only. XXX rear brake pads had been cutting into rotors a few days prior. I had to purchase a tool and pads to replace. XXX Documented loss of an additional 4 quarts of oil across 4 dates. XXX subscribed to Kia connect and the app also detected issue fault code P0597. And at a later date the app detected a 2nd fault code P0598 which went away a couple days later. May 14th finally got a hold of Justin Grable (GM Freedom) to discuss options. XXX trade-in is only option being given to me. DOCUMENTED DEFECTS & ROOT CAUSE Code P0597 (Thermostat Heater Control/Open): An electrical/mechanical failure that caused internal engine "hot spots." Engine Failure: Pre-existing piston ring tension loss causing catastrophic oil consumption (1 quart/wk). Consequential Damage: Chronic oil burning will poison the Catalytic Converters and foul all Oxygen (O2) Sensors. As of XXX my vehicle is now consuming 1 qt/day. ac is not working and now giving me 6 codes for engine light.

I'm reporting a fuel tank failure where fuel started leaking from the seal of tank (see photos). My safety & safety of my kids was put at risk, as this could have likely caused a fire.the vehicle was inspected by the dealer who confirmed & stated that the side of gas tank developed a hairline crack about 1-2 inches (see dealer photo) from a road hazard causing it to leak a drop of fuel every 10 seconds, this creating a potential fire/explosion hazard. Though fuel leak problem is confirmed by the dealer, they are trying to put blame that an object caused a strike and created the crack. However, from the photos taken by me, clearly shows leak coming from the seal with no surrounding surface damage. I'm unknown of timing when this problem occurred but noticed this issue into 5 months after purchasing the vehicle from the dealership. The vehicle was purchased brand new, first owner. I believe this problem occurred do to manufacturing defect (possible due to either poor construction or pressure of the single one bar holding the tank in place). The gas tank only has one bar in the middle holding the entire up the tank, this could have likely caused the crack due to pressure with constant usage of vehicle. As stated prior, the vehicle presents with no hit or incident, so unlikely to have this happened due to damage. Dealer denies issue could have been a defect and states due to a crack from road hazard, again there is no impact/hit marks on the surface of tank or near crack. In addition, no warning lamp or message came on to notified me of this potential treat. The dealer mechanic & supervisor was made aware of this. I am concern about the saftey of this vehicle as it can be a hazard & the beginning of series of complaints against this particular Model of KIA car, as evident from other KIA models where the fuel tank was reported leaking as well. Please make awareness to this potential problem from the KIA tellurides , as this is a newly manufactured vehicle.

I purchased the 2021 Telluride (former owner of a Sportage, Rio and Sorento). I have our local mechanic handle maintenance and service. After paying $1,400 for a tune up to address misfiring, we quickly concluded the transmission was shot and my engine was burning theough every drop of oil before it was due for a change. I went to Kia of Des Moines, since it is covered under a 200k/20-year warranty. They replaced the transmission under warranty, I shared my mechanic details for records, and they told me they were going to do an oil consumption test. They sent me on my way, asking for me to return after 1,000 miles. I did (and then my car began shaking, but we thought it was due to snow conditions) and they quickly said, "Yes, it is an issue!" My Telluride burned through almost 2.5 quarts of oil in 1,000 miles. I left on 12/15, being told they would have direction from Kia corporate on next steps and acknowledged I need a vehicle loaner during repairs (single disabled mother, who has to travel safely). I did not hear back, chasing for updates. Yesterday, Steven text me saying I would need to authorize $1,600 engine tear down fee in order to confirm issue. I asked for Denny, the manager to contact me. I also called Kia Care, who said it is up to dealer. I am seeing so many issues with Tellurides burning oil. And, I do not have $1,600 to make my vehicle safe - that amount would make me sacrifice my home or another necessity. Google said to fight it and to submit a form to you also. I have to fight this because I have no other choice than to sell an organ. I will stock up on oil to keep filling it so my engine doesn't blow up, but have incredible fear of being stranded and not being able to get my vehicle towed or us home safely. If there is anything you can assist with, I appreciate it. I just found out my parent's 2023 telluride is burning too much oil too - they haven't got the $1,600 sticker, but I know that amount will wreck them also.

The 3.8L Lambda II GDI V6 engine suffered catastrophic failure at approximately 102,000 miles. The root cause is excessive oil consumption documented by an independent repair shop well before the 100,000-mile powertrain warranty expired. At 81,207 miles, during a routine oil change, the mechanic checked oil level before draining and found nothing on the dipstick. Only about 3 quarts drained from an engine with 6.9-quart capacity, meaning nearly 4 quarts were consumed since the last change. This finding repeated at 88,408 miles, with the shop documenting it was the second time oil was critically low. Both events occurred within the powertrain warranty. Original invoices are available for inspection. At no point during ownership did the vehicle display any warning — no low oil level indicator, no low oil pressure warning, no check engine light — despite oil levels falling dangerously low on multiple documented occasions. The absence of any driver alert while the engine operated with less than half its required oil is a serious safety deficiency. The engine failed on while driving with passengers including three young children, causing complete loss of power and requiring an emergency pullover. Loss of engine power at speed creates serious crash risk. The vehicle was serviced at an authorized Kia dealer at 60,449 miles where a 60K service, multi-point inspection, and recall SC243B were performed. The dealer made no mention of oil consumption, did not reference TSB ENG222 (addressing excessive consumption across multiple Kia engine families), and did not perform an oil consumption test. Kia Consumer Affairs refused to submit a goodwill claim and closed the case, citing incomplete oil change documentation — despite the defect being documented within warranty. Excessive oil consumption in 2020-2021 Tellurides appears systemic based on numerous owner reports describing the identical pattern: extreme consumption, no dashboard warnings, and eventual engine failure.

In August 2025, my Kia dealership serviced my 2021 Kia Telluride and billed me for 7 quarts of oil as part of the repair. Approximately four months later, in December 2025, the vehicle developed severe engine problems and became inoperable. The dealership diagnosed the failure as a collapsed timing tensioner and stated the engine required complete replacement. Kia Techline agreed with that diagnosis and used it as the basis for recommending a new engine. Despite acknowledging that engine replacement was necessary, Kia denied warranty coverage, leaving me responsible for an estimated $11,000 repair. I then obtained a second opinion from an independent, reputable repair facility. After inspecting the vehicle, the shop concluded the engine failure was not caused by a timing system failure. Instead, they found the engine contained only about one quart of oil and determined the damage resulted from oil starvation. They further stated that, in their professional opinion, the dealership had misdiagnosed the vehicle and that the low oil level was consistent with the possibility that the dealership failed to add the oil for which I was charged during the August 2025 service. What is especially concerning is that the dealership never documented or informed me that the engine was critically low on oil. Because the timing components rely on engine oil for lubrication, I believe it would have been impossible to properly inspect and diagnose a timing tensioner failure without recognizing and documenting the severely low oil level. Based on the independent inspection and the dealership's failure to identify or disclose the lack of oil, I believe the dealership either failed to perform the service as billed or failed to correctly diagnose the true cause of the engine failure. I am concerned that this incorrect diagnosis diverted attention from possible negligent workmanship during the prior service and led to an unnecessary recommendation for an $11,000 engine replacement.

Well, what I thought to be a solid build has succumbed to the known issues with this vehicle. The car has 17,7862 miles on it. I always follow the ‘severe’ maintenance schedule along with babying the heck out of it. I was driving the vehicle on city street, roughly 35-40mph when I got the Xmas tree of death light up on the dashboard (all the indicators went crazy), and a slight loss of power with engine and transmission. I shifted the gear shifter into manual so I could at least control the car and make it safely back home. Once I parked, I shut off the car and then turned it back on. The indicator lights turned off, however the check engine light stayed on. I swapped out the battery for a new one and that fixed the problem for a few hours until later that day the same thing happened again. At this point I know there is something more happening electronically that is not right. Hence the problem: The UB module assembly behind the dashboard needs to be replaced because it is defective (full disclosure, this is what I believe to be the issue, but will be scheduling appointment with dealer to have them look). Ah, but thank goodness for the Telluride forum that has brought to my attention many issues that I also experience with my vehicle. I too have a crack in my windshield that happened three months in (thankfully I have a film on the windshield that has kept it from spidering), I too have to hand wash or touchless wash car due to nightfall trim peeling (thankfully I have car ceramic coated so hopefully that is helping the longevity), I too feel the binding and slipping in my AWD system as I try to accelerate a turn from a stop. It would behoove Kia to address the ongoing issues with their ‘top selling SUV’ as clearly there are still many vehicles popping up with problems. I will say pay attention to the warning signs. Roughly a month ago, the forward parking sensors failed due to ‘blockage’. I should’ve known it would lead to a larger problem. This could’ve been bad!

I purchased my 2021 Kia Telluride S new, with only 22 miles from the test drive. XXX (approx. 53,000 miles, vehicle age 18 months): The transmission failed while I was traveling approx. 75-80 mph on a major highway in [XXX]. Upon failure, the vehicle suddenly lurched as if the brakes had locked or the parking brake had been applied, nearly causing us to strike our heads on the dashboard and creating a hazardous situation for other traffic. After the failure, the vehicle would only operate in approx. first through third gears and reverse, and would not exceed 25 mph. We were forced to limp the vehicle off a busy six-lane highway. XXX: Due to parts delays, the vehicle was not returned until November 2022 after the transmission work. XXX (approx. four months later): The vehicle developed engine knock and excessive oil consumption. Advised this may have been related to oil degradation while the vehicle sat waiting for parts. Since then, I had to regularly check and add oil between oil changes. Despite low oil levels, no oil pressure warning light ever appeared. XXX (exact date unknown): While opening the sunroof at a stop, a loud crack occurred and pieces of the sunroof track, plastic and metal, fell onto me and my passenger. The glass is intact but became partially stuck open without the track to guide it. XXX: The engine knock worsened and became a squeal while driving approx. 60 mph. The vehicle lost power, requiring me to turn on hazards and coast off to avoid accident. Dealership mechanic advised that the engine had thrown a rod and blown the oil filter housing gasket. The vehicle is currently at the dealership and available for inspection. Kia has denied coverage despite the failure of a component linked to excessive oil loss and a recently extended 180,000-mile warranty, even after the engine threw a rod following a sudden loss of oil pressure. The failed transmission has likely already been disposed of. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

On [XXX] my vehicle had a collision warning signal, then tire pressure, then brake lights and entire dash instrument panel. I parked the vehicle, then later in the evening test drove it again and the panel lit up again, in addition to the loss of the speedometer, tachometer, gear display, and drive mode display, so I immediately drove it to Courtesy Kia in Altoona, PA. On 4/18/25 Wendy Giordano of Courtesy Kia confirmed vehicle intake Courtesy Kia reset codes and was unable to replicate or diagnose a repair. The vehicle was returned on 4/23/25 despite my expressed concerns over safety. On [XXX] the vehicle again displayed the collision warning and the instrument panel lit up again, in addition to the loss of the speedometer, tachometer, gear display, and drive mode display. I got off the highway and limped the vehicle closer to my home, stopped for a brief time, and proceeded the three miles to the dealership. In this time I lost power steering, and eventually brake lights and turn signals within 1,000 feet of the dealership and was nearly collided with in front of the dealershipOn 5/12 I continued to ask status and request a loaner with no adequate follow up. I was bounced between JT, Tyler and Wendy Giordano my service advisor. Around 5/22 I called in requesting an update and was put on the phone with the service tech to describe my issues On 6/6/25 John from courtesy ford left a 2 minute long rambling voicemail, 6/3 he said he received a fax. He said he spoke to service department and I could drive the car, that I could be driving the car now. "he wasn't sure what was going on with it" They've driven it and can't find anything. Kia is looking at video, service rep there on Tuesday and find nothing wrong. I think, how long and haven't had it long. Suggest you "just drive it, I don't know" In addition I've followed up with numerous emails and calls to determine course of action and repair and haven't had a productive repair plan.
