Open the full vehicle complaint log (all categories)I was driving very slowly in my driveway. I turned to enter my garage. As I put my foot on the break, the car accelerated crashing into my house. There was sudden unexplained and unintended acceleration on my RAV4 prime.
I was pulling into a parking space at a slow speed and breaking when my car accelerated violently and caused me to go across a median and strike another parked vehicle. Police came and did a report. I took my car right away to dealer and they had me take it to their collision shop to be repaired. They said they would try to find the unintended acceleration problem after it was repaired. No warning lights or airbags.

We have COMPLETELY lost brakes on MULTIPLE occasions for a few seconds per occasion. Brake loss has occurred upon slow, even braking and on flat, dry, even pavement with no pot poles or loose gravel around. When this happens, an orange light appears on the dash, we lose brakes for a few seconds, the car regains brakes, and jolts forward with no change in foot position on the brake pedal. We have taken the car to the dealer multiple times and every single time this incident has occurred the rear right wheel speed shows about a 10% variation in speed compared to all the other wheels per the vehicle diagnostic report/record of behavior. The orange light we are seeing on the dash is the ABS light. There is no feedback in the brake pedal on any occasion. This incident has occurred about 20 times so far. Our car is available for inspection. The dealer believes this is being caused by a software issue and not a faulty sensor. This car is a danger to us and anyone around us as we have needed to swerve into the shoulder multiple times to avoid hitting someone ahead of us. This NEEDS to be fixed before it injures or kills someone. This issue has still been persistent even after taking care of the VSC recall and a reset/recalibration to the braking system. We have taken the car to the dealer for this issue on: 4/4/22, 4/15/22, 4/25/22, 5/11/22, 6/4/22. *We have been limiting our driving in this car due to the issue happening multiple times a week, that is why there hasn't been many trips to the dealer much between May and June. I want to reiterate, this doesn't sound like a defect per the dealer, it sounds like a software issue!
