2022 TOYOTA RAV4 PRIME Complaints
I was beginning to slowly back out of a parking space in a super market parking lot. I had not put my foot on the accelerator because my car begins to slowly inch backwards once it is put into reverse. As the car began to inch backwards, I saw a car approaching down the parking lot driveway behind me. I immediately stepped on my brake, but instead of stopping, my car began to race backwards, accelerating at a fast speed. The car never responded when I put my foot on the brake, so I was unable to stop the car. This caused me to crash into the car driving past me, and that finally stopped the car. Because I was almost perpendicular to the car I hit, and the driver was unable to get out of his car, I then put my car into drive to move it out of the way. My car accelerated out of control, again, this time forward. Again, it did not respond when I put my foot on the brake. My out of control car was quickly heading toward a large metal fire gate. In complete desperation, I stomped very hard on the brake, pressing it to the floor as I was about to hit the gate, and the car finally stopped. In both incidents, my brakes completely failed to stop the car accelerator which was acting on its own. The problem has not been reproduced by Toyota, which says there is nothing wrong with the car. However the data report they gave us is suspect because the data shows no reverse movement of the car and labels the accident a rollover, which it was not. In addition, the inspector told my husband there were more tests he could do, but Toyota had not authorized him to do them. There is a police report, and a witness who observed the whole thing. She said that because of the way the car was moving, it looked like a hit and run accident with the driver trying to make a speedy getaway. There were no warning lights or messages displayed.;
