There are 7 owner-reported electrical system complaints for the 2021 Lincoln Aviatorin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The vehicle is intermittently braking on its own while driving. The issue has become significantly worse over the course of a month. The dashboard message reads, “brake applied, power reduced”. This is a danger to both myself and other drivers as we are unable to control the speed of the vehicle.
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.
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. I have included screenshots from the video (the system won’t let me send the video) I took replicating the issue with it completely crushing a box at the height of my head.
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.
Three times, battery was dead -- twice within 24 hours of bringing the car home from the dealer. We only drive the car home from the dealer, then the next day the battery is dead again. The dealer said they replaced the battery and fixed an electrical recall, and they said they checked for electrical draw, but the problem is still there. Yesterday, they said they contacted Lincoln corporate because they didn't know how to fix it. It is dead again this morning. We get messages on our phone app about the anti-lock bake system, hill start assist warning, charge system fault, pre-collision assist, security system, etc. And the alarm goes off. Please see if this is a common issue? It is a Black Label, so they are "fixing" it for free, but it really isn't being fixed.
The backup camera and 360 degree camera periodically malfunction and display a blue image. The backup camera does not work again until I restart the vehicle. This has happened both on a roadway while parallel parking and in a parking garage.
