Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The auto mode on my Sync screen on my 2021 Lincoln Aviator does not always automatically switch between day and night based on ambient light levels. This is a blinding experience at night when the screen doesn't switch to night mode and the brightness is intense. This blinding screen makes it hard to see outside when it is dark which could lead to an accident. My dealer says I have the most up to date version of Sync for my vehicle and there is no fix for this problem.”

“My 2021 Lincoln Aviator PHEV lift gate safety stop does not function properly. It will come closing down extremely hard. This will happen when the button is pressed on the lift gate or the hands free feature is triggered. The lift gate will not safety stop and pop back open as it should unless a significant amount of force is used; this is usually 2 or more people trying with all their strength to stop it from closing on them. I have been hurt by this and so has my child. This is a serious safety issue. …”

“My vehicle’s camera system, including the backup camera, is experiencing an issue where the passenger-side camera fails to display properly, showing only a blank black area. I have reported this issue to my dealership for future inspection. It is not yet clear whether the problem persists during daylight hours; however, it poses a significant safety risk at night when visibility is already limited. The loss of the passenger-side camera view creates a blind spot that could increase the likelihood of an accident or injury.”

“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. …”

“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. …”
