Toyota Prius sudden acceleration problems

Filed Oct 17, 2026 · CA · crash

I experienced sudden unintended acceleration. While I was making a right turn from the street to my driveway, my car suddenly accelerated on its own and hit the side of the house and the garage door, causing significant damage to the house and the front of my car. My street is uphill, so my car was almost stopped when I made a turn. My car suddenly lurched forward passing the upward incline to my driveway. The windshield cracked due to fallen bricks from my house. I heard the noise of sudden acceleration, and the next thing was my car hitting the house hard. I had my foot slightly on the brake. My chest hit the wheel due to the shock, but the airbag was not deployed. I experienced a mild concussion to my chest.

I turned left into a parking space in my 2020 prius. I stepped on the brake, and my car shot forward. I couldn't stop it, and it hit a concrete pole. It only took 1 second. It seems toyota hybrids are still having this unintentional acceleration despite a multi billion dollar law suit in the early 2010's. My car was towed and is awaiting inspection by my insurance company. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

While pulling out of a parallel parking spot going slightly uphill, I braked as I looked around the back of a double parked truck. I saw a car coming, braked hard, and suddenly my car surged forward across the street and hit a parked car. I looked down and saw that my foot was squarely on the brake pedal pressing down as hard as I could. The parked car was unoccupied, and I was uninjured. There were no warning lamps, messages, or other symptoms of the problem. I turned my car into the dealer for repairs and a fix to the sudden unexpected acceleration. They could offer no fix until a Toyota representative examined the car. On August 14, by an emailed letter, Toyota claimed it found no defects and it must be the result of driver error, specifically, my mistakenly hitting the accelerator. This is gaslighting denialism. (a) The EDR data sent to me does not indicate that I hit the accelerator unless that data is in the page of hexadecimal numbers. (b) Toyota's claim that I hit the breaks at "-0.2 seconds prior to the collision" is physically impossible. No one can move their foot from the accelerator to the brake that fast. (c) Toyota's claim is contrary to what I experienced and observed.

About a year ago and again a few days ago, I was slowly moving my Prius forward when suddenly it accelerated at full speed. The first time I was pulling into a parking spot beyond which was a grassy area and then a stockade fence. When I felt the car lurch forward, I slammed on the brakes, but was still going quite fast. Fortunately, the collision avoidance brakes kicked in and stopped the car just before I hit the fence. In the second case, I was slowly pulling into a parking lot when again the car surged forward. This time I was able to stop the motion with the brakes myself . In both cases I was conscious of moving my foot from the gas pedal to the brake pedal. In both cases it was a hot summer day, near 90.
