Kia Sportage 2021- The service department at the dealership ran basic inspection of fault codes and found fault in system for knock sensor and camshaft b position sensor. These codes have relation to engine failure or possible timing chain failure. My safety was put at risk as I was driving down the highway and my car would not go over 40 miles per hour and cars were serving from hitting me from behind. Then my check engine light came on and started flashing. This information on my vehicle was looked at the dealership I purchased my vehicle, and they do not have the software/special tools to repair/replace timing components and vehicle was towed to Kia dealership. There was no warning lamps or symptoms that warned me before it happened. Once it wouldn’t go over 40 mph (wouldn’t accelerate) and my car light came on and blinking I pulled over.

My vehicle is burning oil. In a little over 1500 miles after I get a oil change from the King Kia Dealership Service, my oil stick shows that the level of oil in my engine is none at all. When I check my oil, the stick, is absolutely dry. This has happened in the last 3 oil changes with my vehicle. There is no oil indicator light that comes on in the dash, but the oil stick is dry. Additionally, there is no indication of oil leaking from my car in my drive way. I will be returning to the King Kia dealer service for the third time on 10/13/25 for remedy of this situation. I contacted Kia Customer care and reported this situation and received a case number: [XXX]. I currently have 75,943 miles on my vehicle. To prevent engine damage, I've added quarts of oil to my vehicle to compensate but I'm most concerned that this oil is prematurely burning.

I have owned 3 kias and all 3 have had recalls. KIA has never contacted me and dealership has told me it's not involved if you didn't receive info. As things started to go wrong like ABS sensor lite going on and off dealer said nothing they could do unless they could get a code while it was on so I had to drive the car with the issue until it stayed on consitently so they could figure it out. This happened on 2 vehicles in a row. My husband traded his in for a truck and got away from KIA. I traded in and ended up with a 2021 with less than 6000 miles at this point. I have contacted KIA headquarters still have no idea what the recall is for. All I have heard is on the news advising not to park car inside or near house due to chance of car catching fire. At this point I have not used the car in about 2 weeks I'm afraid to, but I have a lovely lawn ornament that cost me over 500 a month. I would like KIA to buy back the car so I can get something I have trust in like a Chevy. Never had a recall on that in fourty years. Will never buy anything but America made again.

I have experienced chronic and excessive engine oil consumption in my 2021 Kia Sportage S with the 2.4 L Theta II engine. Since around 80,000 miles, I have had to add oil every 2 weeks between oil changes to prevent the engine from running low. My vehicle now requires a complete engine replacement, estimated at $10,000. Despite regular maintenance and oil changes (documented by Express Oil Change in Pinson, AL, with service records at 81,520 mi, 88,215 mi, 94,153 mi, 96,970 mi, 98,902 mi, 101,522 mi, and 105,273 mi), the vehicle continues to lose oil rapidly. Kia and my dealer have confirmed there are no recalls or warranty campaigns for my VIN, even though this issue is identical to the well-documented engine defect affecting earlier Kia models covered under the Theta II engine settlement. This defect creates a serious safety risk, as the engine can run dangerously low on oil between services, leading to engine failure or stalling while driving. I am currently out of work recovering from surgery and cannot afford the $10,000 repair. I am requesting that NHTSA investigate and expand the existing Kia engine defect recalls to include 2021 Sportage models using this engine.

On March 4, 2026, the engine in my 2021 Kia Sportage malfunctioned while I was driving on a local road on Long Island, NY. The check engine light illuminated, the vehicle lost the ability to accelerate normally, and the steering wheel became heavy and difficult to turn at the same time. This created a serious safety risk, as I was unable to maneuver or accelerate normally and could have been stranded in an active roadway or unable to avoid a collision. The vehicle was able to restart but was towed as a precaution and transported to service. An independent repair shop examined the vehicle and identified the issue as an engine problem, advising that the repair should be covered by Kia. I delivered the vehicle to Kia Smithtown, an authorized Kia dealership, on March 9, 2026. As of today, the dealership has had the vehicle for approximately six weeks and has not yet completed a formal diagnosis or begun the repair, and no loaner vehicle has been provided. No police or insurance inspection has occurred. The check engine light first appeared at the moment of the failure on March 4, 2026; there were no clear warning symptoms prior to that. The vehicle remains in the possession of Kia Smithtown and is available for inspection.

Government / agencyIndexed Oct 9, 2026Source-linkedVerify source — NHTSA complaint #11752678

On June 14, 2026, the driver experienced sudden rough engine running followed immediately by a flashing check engine light. The vehicle was towed to the selling dealer, which has performed all prior maintenance. The vehicle is currently at the dealership and available for inspection. Technician notes show DTC P1326 was stored — the Knock Sensor Detection System code associated with connecting rod bearing wear on Kia's Theta II engine family. The technician performed an audible knock check only (none heard) and cleared the code. The vehicle was found approximately 2.5 quarts low on oil due to an internal turbo oil leak. The dealer's notes state the code "may be related" to low oil — hedged language, not confirmed causation. The dealer confirmed the turbo failure but has not performed a bearing clearance test to confirm or rule out bearing damage from the low oil condition. The dealer performed a turbocharger replacement. Despite a verbal commitment from the service manager that a bearing clearance test would follow, no such test was performed 40 days later. When the vehicle was declared ready, the service manager did not recall the commitment and suggested driving 40-50 miles as an alternative. Kia America opened a formal case last month and authorized a partial goodwill adjustment but no one has addressed the safety concern of the unperformed engine test indicated by the thrown code. Driving a vehicle with potential connecting rod bearing wear risks catastrophic engine failure, creating a serious safety hazard. This vehicle has a documented history of oil consumption prior to this incident. The engine has not been cleared for bearing damage following a significant low oil event and a stored P1326 code.

On Thursday [XXX] I purchased a 2021 Kia Sportage LX from Liberty Auto Plaza Dealership located in Libertyville, IL. During this purchase, the salesman Isaac told me the car was updated with Anti-Theft Protection. Between Friday [XXX] evening and Saturday [XXX] my Kia Sportage that I just purchased was stolen. I called the police department and made a police report and I filed a claim with my insurance company, American Alliance Casualties. My vehicle was recovered on Wednesday [XXX] and the insurance company picked the vehicle up on Friday [XXX]. My insurance company, American Alliance Casualties has had my vehicle since. [XXX] will be five months this company has had my vehicle. On [XXX] American Alliance sent me an Offer Letter to, either have the vehicle to be repaired or, have a direct check sent to me. I choose to have the vehicle repaired because I wasn't looking for money I wanted my car repaired. The company I chose was Fender Mender Auto Collision Center. I spoke with their receptionist, Heather on, Thursday [XXX] and she said my insurance company, American Alliance Casualties delivered my vehicle to their facility and they were going to start working on it right away. I called Monday [XXX] to follow up and see how is the progress going to repair my vehicle and she told me that there was something going on with the engine. On Monday [XXX] Heather from Fender Mender Auto Collision called and said my claim was denied because there is wear and tear on the engine. The engine has 27,000 miles from the time it was stolen so that's impossible. However, I spoke with the insurance adjuster Annette Khatib and she said the inspector stated there was a blockage in the engine possibly due to a manufacturer defect.

Government / agencyIndexed Oct 9, 2026Source-linkedVerify source — NHTSA complaint #11729133

I am filing a complaint regarding a 2021 Kia Sportage that experienced catastrophic engine failure, leaving the vehicle non-drivable despite regular maintenance and documented oil changes. I brought the vehicle to an authorized Kia dealership, located at 402 NJ-35, Keyport, NJ 07735, for evaluation. On or about March 17, 2026, I was informed by the dealership that coverage for engine replacement had been denied. At that time, I was not provided with a clear or sufficient explanation for the denial. Due to the lack of explanation and assistance, I escalated the matter to Kia corporate and was assigned a case manager. On March 30, 2026, I was contacted by my assigned case worker from Kia corporate, Marcia, who confirmed that my request for engine replacement remained denied. Again, no specific or sufficient explanation for the denial was provided, despite my attempts to obtain clarification. I made multiple efforts to understand the reason for the denial and to resolve the issue directly with both the dealership and Kia corporate. Despite these efforts, I was not offered a reasonable solution, nor was meaningful assistance provided. The vehicle ultimately stalled out in the middle of a highway. As a result, I am now left with a non-drivable vehicle and a significant financial burden, including an outstanding loan balance on a vehicle that cannot be used. I am also aware that there have been reported concerns, recalls, and investigations involving engine issues in certain Kia vehicles. While I understand each case is reviewed individually, this raises concern that my situation may not be an isolated incident and warrants further review. I believe this outcome is unfair given my documented maintenance history and the severity of the engine failure. I am requesting assistance in obtaining a fair resolution, including reconsideration of the denial and/or financial assistance toward the cost of engine replacement.
