NHTSA complaint #11539079, filed 2023-08“I purchased my vehicle in 2020. In 2022 I experienced an issue where my car stopped in the middle of the road without warning.

NHTSA complaint #11770409, filed 2026-10“On the morning of October 25, 2021 at approximately 7:05 am, I was fixing to leave to go to work. The carport light was on, so I open the door to my car, slid into the driver’s seat, started the car up and the lights came on. As I was starting to get out of the car to go turn the carport lights off, I realized the car was going backwards. I tried to get back into the driver’s seat to try to stop the car but I was unable to do so. The door knocked me down on the concrete floor of the carport and the front left tire ran over both my legs. …”
