Airbags deployed prematurely as I was parking my car in a doctor's office parking lot. The car was going less than 5 mph and I did not hit anything. The premature deployment of the airbag startled me and caused me to hit the accelerator instead of the brake and I ended up crashing my car into a nearby pole and another .automobile. The accident resulted in a soft tissue injury for my daughter and I'm experiencing lower back pains. The air bag caused burns on my nose and arms. My daughter has bruising on the arms from the air bag deployment

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2018 Toyota Prius Prime verdict →
