CrashFiled: Sep 2025

While turning into a parking space, you pressed the brake pedal but your 2020 Prius suddenly accelerated forward instead of slowing down. The car hit a concrete pole within one second and you were unable to stop it. The vehicle has been towed and is pending inspection by your insurance company. This issue may involve the brake system, accelerator pedal, or engine control electronics and will require professional diagnostic evaluation.

Your Prius has experienced sudden unintended acceleration twice while parking—once a year ago and again recently. Both times occurred on hot summer days (around 90°F) when you were slowly moving forward and deliberately moved your foot from the gas to the brake, yet the car surged forward at full speed. In the first incident, your car's collision avoidance braking system prevented a crash; in the second, you were able to stop it manually. The cause appears to be a malfunction in the throttle or engine control system that needs diagnostic evaluation.

Your vehicle came with original tires from the dealership. While no crash or fire occurred, original equipment tires may wear unevenly or perform differently depending on driving conditions and maintenance.
