“I was trying to back up in area with a lot of young children around. When I put the vehicle in reverse and looked at the camera screen, it had completely died. I have been unable to get the screen to work since. It does not do any good for the NHTSA to require back up camera systems if they fail after a few months. The safety benefit of requiring a system on 2018 vehicles if the system fails completely before the end of 2019 is not good.”
NHTSA complaint #11257194, filed 2019-09, 28,600 miles“The car was in stationary mode on a city street and waiting for the red light to turn green. After a few minutes, the turned green and I accelerated a little as the car begin to move but out of nowhere the car turned off and all systems stopped, including the computer board, but before all went blank there was a message about system error with a triangle symbol, and I had to manually activate the parking lever as well as press the brakes. Thankfully everyone in their lanes noticed my odyssey and made space for the other upcoming cars as I activated the emergency flashing lights. …”
NHTSA complaint #11299994, filed 2020-01, 10,264 miles“On sunday, october 20, 2019, approximately 3:10 pm I got into my 2018 Toyota Corolla, the car was stationary in park, and was not running on a flat surface. I realized I forgot my wallet so I got out of the car and left the driver's door open. I retrieved my wallet within 1 minute and when I came out my car was rolling slowly on the flat driveway where I park every day. I tried to grab the door handle to see if I could jump in the car to stop it but it picked up speed and went down a slight incline across the yard. The door hit a tree and then the car landed in bushes. …”
