What owners wrote

A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

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.

August 2025 Injury

My vehicle has heated seats. This week, when I was using the heated seats, I noticed a burning sensation on my left buttocks. I later discovered a burn hole in my seat (bottom left) and a matching burn on the coat I was wearing (bottom left). I am reporting this incident I because I believe there is a defect of the heated sweats in my vehicle that could lead to severe burns to passengers.
