NHTSA complaint #11396567, filed 2021-02, 106,500 miles“I was alone in the car and had driven into my driveway (after opening the garage door) to enter the garage. The car suddenly took off and before I knew, I had crashed into the side of the garage and went through it.

The garage door railing was damaged and the door was hanging a few inches above my car. I heard things falling above me. …”
NHTSA complaint #10577514, filed 2014-04, 76,011 miles“Car makes a very, very loud screeching sound when started with A/C or heating on (but more commonly with A/C).

Sound can be heard mainly upon inital startup but can occur after car is in motion.”
