Government / agencyIndexed Oct 9, 2026Source-linkedVerify source — NHTSA complaint #11764001

The Driver Seat Module (DSM) is known to develop software glitches across the 2020–2024 Aviator/Corsair/Explorer platform, causing the seat to not move to the correct programmed memory position . Lincoln’s fix (per Special Service Message 51406, issued for Corsair but describing the same shared module) is a dealer reprogram of the DSM software. However, this did nothing to improve the problem. •Symptoms include complete loss of seat adjustment where switches do nothing and the seat is stuck in place, memory functions failing to recall saved positions, intermittent operation with clicking noises but no movement, and the easy entry/exit function drifting out of correct position over time. Additionally, the drivers seat bladders and actuators engage without driver input and the seat controls on the touchscreen, increase and decrease bladder input and motor control beyond the selected settings. This often HAPPENS WHILE DRIVING.

I have been having issues with my breaks sticking when applied. To the point that it’s completely stopping my car and i need to use my foot to release the brake from behind. I have had the dealership look at this issue and they can’t seem to find the problem. They also broke my car and claimed they did not feel the sticking. I’ve had the dealership look at my vehicle twice for this issue. It is a safety risk with children in my vehicle. Also everyone i lock my vehicle. My alarm is going off saying someone is opening the door on my Lincoln app. Additionally, every time i start my car it says the passenger door is open, when it’s not. The sync Bluetooth constantly connects and disconnects or if i plug my phone i to the charger for CarPlay it does not work. This biggest problem is my brakes sticking. Like i said when i am braking gradually they are sticking to the floor and not releasing. Thai doesn’t always happen but it has happen a lot recently. I need this fixed!!!!! Multiple recalls that are not available as well

UNKNOWN ON several occasions the vehicle would just shut off. Another occasion while getting on the freeway I pressed the accelerator pedal and the car pumped the brakes,there was no one in front of me or on side of me upon entering the freeway. Another incident I was in the fast lane on the freeway and the vehicle just shut off Thank goodness the fast lane had a place where I could pull over and and restart the vehicle. Also where the vehicle pumped the brakes, that happened on several occasions. Another thing the vehicle shut of again in the middle of the street. I couldn't put the car in neutral the steering was locked. All of incidents were extremely dangerous. The vehicle has been in the dealership shop twice now and I mentioned it to them on both occasions. And I was told it was the battery. That starts the engine not battery for the eclectic system. I was also told that they did diagnostic check of the software system and there were no systems alerts it was only showing the battery. Now I now that when you drive a vehicle the engine battery charges, plus the vehicle in a 2021 with only 35,000 miles on it.

Government / agencyIndexed Oct 9, 2026Source-linkedVerify source — NHTSA complaint #11697630

For the first 39 months of my ownership my 2021 Lincoln Aviator Grand Touring plug-in electric hybrid would not charge properly and resulted in thousands of charge station fault alerts. The dealership was dismissive of the issue for years because it seemed to work for the few minutes when they charged it on their high voltage charger even though I voiced concerns about the charger port being bad on the vehicle and it not working properly at home. My Aviator would not charge unless the plug was in the exact perfect spot and rarely would make it to a full charge before faulting out. Eventually the port started making SPARKING NOISES, ELECTRIC FIRE SMELLS, and SMOKES when plugged in. I was afraid my Aviator was going to start a fire and burn my house down, so I stopped charging it for at least 6 months until a new service manager finally took the time to investigate the issue. It was found in May 2024 that not only was the charger cable that came with my Aviator when I bought it defective but so was the charger port on my vehicle. The use, value, and safety of my vehicle impaired significantly for several years by this issue. I am reporting this so that there is awareness that the Aviator plug-in hybrid charger port and charger cable can be defective which results in loss of charging capability and could result in a fire.

I have been reporting an issue for over two years with multiple dealerships regarding a sulphur and other strong exhaust smell. This Sulphur smell is most problematic and occurs most often at least one per day. This issue started off intermittently but is now occurring as increase frequencies. The Lincoln dealerships tell me this is normal. I am not sure what system is exactly failing as no codes are being presented (so says the dealership. This smell is so strong and can be easily smelled in the car but even more once opening the doors or hatchback. I have children that breath this air as well as myself. Often children (my own as well as school friends for which we give rides to) complain about this smell and it is very noxious in nature. This issue has been reported to the dealership MULTIPLE times (Actually reported to two dealerships). Often, I am being told this is "normal" due to gas used. In beginning they would not even log my concern, but this past year I have been submitting online. Always no code so no issue. No other troubleshooting is done. I have even requested additional basic troubleshooting data and not received. This is not a normal smell, as the Lincoln dealership(s) suggest. This smell makes us feel unpleasant. This smell is strong and is hazardous to the health of my family and others. I need Ford to take this issue seriously. Symptoms experienced indicate there is likely a problem with the catalytic converter and they are not addressing.

1.) Exhaust System Failure (Flex Pipe / Catalytic Converter) The vehicle’s exhaust system—specifically the flex pipe connected to the catalytic converter—cracked and malfunctioned. This component is available for inspection upon request. As a result of the failure, exhaust fumes entered the cabin, creating a significant safety risk due to potential exposure to carbon monoxide. Prior to the failure, I noticed a persistent rattling noise at low speeds and while the vehicle was idling. The issue was inspected and confirmed by the dealership; however, I was informed that the repair falls outside of warranty coverage. I would like to know if this falls under safety hazard for emissions. 2.) Sunroof Glass Shattering Incident While driving, the sunroof glass suddenly shattered and appeared to implode outward. According to the dealership technicians, this may have been caused by thermal stress or frame-related tension. The glass is no longer intact but the remaining components and frame can be inspected upon request. The incident posed an immediate safety hazard to both myself and other road users due to the sudden loss of glass and the potential for debris. I did not observe any warning lamps, messages, or symptoms prior to the failure. After researching the issue, I found that similar sunroof glass failures have been reported across various Ford/Lincoln models, suggesting this may be a known manufacturer defect. The dealership has confirmed the damage but no inspection by the manufacturer, police, or insurance representatives has been conducted at this time.

Hello. My name is [XXX] and I have a potentially serious issue with my car and Lincoln refuses to look into it. The short story : When you press the brakes moderately or harder (as if stopping for a yellow light) it sounds like you’ve run over a brick or hit a BIG pothole. It has been in 6 times and to 3 dealerships and they all say it is normal for Aviators and Explorers. I have owned an auto repair shop for 12 years and my guys fix 2000 cars per year. I am an ASE master certified mechanic and I can assure anyone that there is nothing normal about this bang. They tell me they drive a like vehicle and if it also makes noise, there is nothing they can do. I have reached out to Lincoln Concierge multiple times and they tell me they will do nothing if a like vehicle also does it. I think of the 2019 Pacifica that the lower ball joint pinch bolts comes out and folds the wheel under the vehicle. I have had 3 service managers drive the car and they have all told me that it sounds really bad and abnormal. I have been told by all of those managers that Lincoln enforces not doing any further diagnostics or repairs if they all do it. I did drive a 2023 Aviator with a service advisor and it did not make the same noise mine does. You can actually feel the noise in the steering wheel. I have pleaded with them to investigate the issue and at least let me speak with a supervisor about it but they refuse. I have asked the dealers to put a set of chassis ears on the suspension to pinpoint the sound and they say Lincoln will not let them. The vehicle has 33k on it and is still under full factory and extended CPO warranty. Can you guys look into this issue before someone gets hurt ? Thanks for reading INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Government / agencyIndexed Oct 9, 2026Source-linkedVerify source — NHTSA complaint #11705685

The driver-side front window regulator failed and was replaced on October 4, 2025. The passenger-side window regulator also failed and was removed and replaced on November 21, 2025. At the time each incident, the window would not raise using the car controls and remained stuck in the down position. Two window regulator failures on opposite sides of this vehicle just seven weeks and within roughly 2,400 miles apart does not indicate typical wear. It reflects a pattern failure consistent with a component defect. At the time of the October incident, I was actively driving the vehicle and the November incident when was while the car was parked, when the window failed and would not raise. After parking and then restarting my vehicle, the window remained fully or partially down and could not be returned to a closed and secured position. This created multiple safety and security risks, including: • Inability to secure the vehicle against theft or intrusion • Exposure to weather, rain, or debris • Increased cabin noise due to broken window • Risk of vehicle damage while parked without protection. The vehicle was left parked and unsecured solely due to the window malfunction. No police or insurance inspection occurred, as the incident did not involve a collision or theft, though the vehicle was left unsecured. The failure was diagnosed and confirmed by the manufacturer, Lincoln and independent service center Firestone Complete Auto Care, who completed the repair. There was No warning lamps or dashboard messages that appeared prior to or during the failure. Both window regulator failed suddenly and without warning. In my research, numerous Aviator owners have publicly reported identical regulator failures, (Reddit and YouTube) which further reinforces that this is a systemic issue, not an isolated event.

In regards to my brand new 2021 Lincoln Aviator Reserve (4181 miles): 2.23.22- Driving home on a very narrow, winding road when my car unexpectedly started to vibrate/shake. There were no alerts and no warning lights that came on. Fortunately, I was coming up on one of the very few turnouts available. As I started to pull over the car completely shut off (completely died). Luckily, I made it off of the road or I would have been stuck in the middle of the road on a blind corner as the car would not restart. It just kept displaying "Full Accessory Power Active" but would not do anything. The car was towed back to the dealership who informed me the next day that the engine had completely seized and they would have to replace the engine. One of the piston rods was bent to a 90 degree angle. I got it back on a Saturday afternoon(3.12.22), drove home from work, took my kids to/from school Monday, then drove to work Tuesday morning. On my way to work (which is only 3 miles from home) my car started to vibrate again but I was able to turn off the highway onto a side road and the vibrating stopped. Thankfully, it did not die in the middle of the highway and cause an accident. I continued on down the street and again the vibrating started. As I pulled up to a stop sign the car completely died and would not start. I waited a few moments and tried again and it started. I was able to make it the last less than quarter of a mile to work while it vibrated then died yet again as I pulled into my parking spot. My fiancé came later in the day and started the car. It was making a loud knocking noise so we shut if off and called dealer again. It was towed back for another new engine. As of today, they are still working on "repairing" the brand new death trap. Lincoln doesn't seem to think it's a big deal and thinks the second new engine will fix the issue. Hopefully it doesn't kill me first. This is worth investigating. Like I said, this car is a death trap.

Government / agencyIndexed Oct 9, 2026Source-linkedVerify source — NHTSA complaint #11683805

My 2021 Lincoln Aviator grand touring PHEV has on 3 separate occasions randomly gone into “brick” mode where power is to some components like the Sync screen, and some lights, but main dash won’t boot, the lock/unlock doesn’t work but lock icon flashes on door panel, the vehicle won’t start. This is after short trips out with my family for the evening. Not a fob issue. All 3 times the same. First occurrence at just over 11,000 miles, again in Sept 2023, and happening again June 2025. Roadside assistance dispatches tow trucks, the vehicle can never be jump started. Electric parking brake is engaged and will not disengage even when manually put in neutral. Always takes dispatching several different tow trucks to get one equipped with skates to drag the vehicle on to a flatbed tow truck, or old school wheel lift truck to be able to tow the vehicle since the electric parking brake will not disengage in this situation. Last time this happened it took 6 separate trucks to come out over 3 days to find one that could tow it in metro Detroit, the heart of the auto industry. This is a defect in the system of my vehicle that poses a safety issue because it prevents a regular tow truck from being able to tow this vehicle. I have had the dealership look at it many times, there is no fix, tech says it is a defect. Each time I have reported it to the Lincoln Customer Experience Center, they don’t care enough to do anything. Not sure how to get help but I’m probably not the only one with this safety defect. There are other safety issues. The safety stop for the lift gate doesn’t always work and will hit you hard without stopping for an obstruction. I also have acceleration hesitation when stopped and turning in traffic, risk for accident. The electrical problems with my Aviator are endless but leaving me stranded with my children and unable to easily get help is a serious problem and unacceptable. Please let me know how you can help. Sincerely a concerned mother of 2 little boys.
