NHTSA complaint #11390410, filed 2021-01, 16,443 miles“I was idling at a parking space and went to turn off my car. The vehicle surged forward and the BRAKE sign came on.

I immediately took my car to the dealership where they kept it for 3 days and said they could find nothing wrong and it was safe to drive. …”
NHTSA complaint #11585051, filed 2024-04“Since October 2023, my 2019 Toyota Prius has developed severe and unpredictable driving behavior after a regular brake service, which may have triggered or coincided with a software or ECU update.

These interventions often happen on highways or during turns, creating serious safety risks for both driver and passengers. …”
NHTSA complaint #11692652, filed 2025-10“Whenever it rains the warning message clean parking assist sensor comes on while you are driving. Even after you clean the sensors the warning continues to beep contiously. You can press the back button but it will not stop. Also proximity sensor comes on with this incident. After the rain stops the problem stops.”
