The contact owned a 2016 Toyota Prius. The contact stated that while switching lanes, the vehicle was rear-ended by another vehicle driving at 30 MPH. The contact's front driver's side seat backrest inadvertently moved backward, which caused her shins to hit the dashboard under the steering wheel during impact. None of the air bags deploy upon impact. The contact later received medical attention at the hospital for injuries to her shins. A police report was filed. The vehicle was towed to a tow yard and deemed totaled by the insurance company. The manufacturer was not made aware of the failure. The failure mileage was approximately 88,000.
