NHTSA Complaint #11538750 — 2020 LINCOLN AVIATOR

Without notice the transmission would downshift and lunge forward. So hard that it felt like we were hit from behind. When trying to accelerate it would stay in gear longer than normal and clunk forward again. Smelled burning through the vents. Also when accelerating it would slip out of gear and the rpms would increase without me being able to move and then shift hard into gear again. We were on the highway at highway speed in traffic and without warning the vehicle wouldn't accelerate and were inches from being rear ended by the tractor trailer behind me. I was fearful for my life and the life of my family in the vehicle. Due to all of the issues with the vehicle it is now causing me financial hardship and undue stress and I am unable to perform my normal job duties due to this issue. The vehicle has been inspected by the dealer and confirmed that this component is bad and needs to be replaced. The were no warning lights when this happened.
