Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“They recalled other models for back up camera navigation issues. My vehicle was having same issue and I paid for repair and update on this issue and mine isn’t part of this recall but should be”
NHTSA complaint #11671037, filed 2025-07“My husband secured our infant into the car seat and attached the seat to the base installed in the car. He then drove our child. When he removed the car seat it was discovered the right side of the seat (when facing) was not clicked in and could be lifted up. When he removed the seat he noticed the clip on the inside of the shell, that connects to the base, was completely missing meaning he had been driving our child only partially secured. When we turned the car seat to take a picture the retractable clip on the outside of the same portion fell out. …”
NHTSA complaint #11766805, filed 2026-09“I was driving about 40 miles per hour on an open road when I heard a very loud popping/explosion sound and falling glass. I immediately pulled over and found my panoramic sunroof had exploded and the glass was dropping into the cabin, most of it being caught by the interior sunroof screen. I immediately drove it to the Lincoln dealer where I bought it. They said they have never heard of such a thing as an exploding sunroof, and said it must have been a projectile hitting the top of my car; I find this highly improbable. …”
NHTSA complaint #11516225, filed 2023-04“Panoramic sunroof exploded without anything striking it. Sound like a gun shot. No vehicles in front of us to have thrown any objects at it to strike it.”
NHTSA complaint #11592737, filed 2024-06“Urgent safety recall. Informed of this urgent safety recall of fires on May 17 and there still has been no resolution by Lincoln to fix this urgent safety issue.”
