2019 TOYOTA PRIUS Electrical System Problems

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 pushed my brake to the floor and nothing happened. I was moving toward a brick wall so I put in in reverse and the car surged backwards. The BRAKE sign came on and I pushed the brake to the floor and again nothing happened and I ended up hitting the car behind me. 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. I just got it back from having the body work done and am afraid to drive it as this might happen again or worse. I am reporting it to let you know and to see if this has occurred and been reported as happening...

On Saturday [XXX], while shifting to reverse in a back alley to back up slowly, the car engine suddenly and loudly revved and shot backwards at accelerating speed. I slammed on brakes which did not respond at all, thus forcing me to attempt to shift gears which also failed to stop the acceleration. Car only stopped because it went up a curb and hit the corner of a parked vehicle in a neighbors driveway. If I had been on busier street and not a back alley this could have resulted in numerous vehicle collisions and unimagined fatalities. Car is being towed on [XXX] to Advanced Collision Repair on 4511 Central Ave, Columbia Heights, for diagnostic assessment. There were no warning lamps, messages or other indicators prior to this terrifying lack of vehicle control . This was first episode since purchasing car approx one year ago. Incident was captured on neighbor’s...

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.
