Example complaints

“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. …”

“Driving this vehicle in snow and ice collects in my wheel wells because of the material used in them. It is felt like heavily textured that the snow and ice sticks to like glue. So, in lots of snow and slush on the road it quickly collects to its limit of area between tire and wheel well and then makes turning or steering the car difficult. It does NOT slide off easily even when going to the car wash to try and clean it off. Or by letting it sit in the sun to melt does not help either for a very long amount of time. …”
