Reported at 70,000 miles, May 2020 CrashInjury

Someone rear-ended my Prius and they were driving a Ford 250 truck pulling a large flatbed truck that had a huge box on it. My seat went forward and backwards - I slammed my knee under the dashboard and then slammed by head into the headrest and I could not reach the pedals after this. I have repeatedly asked the collision center to look at it because there is nothing about it on the report of the estimate of repairs. My adult son was a passenger in the front and his seat didn't move.

Reported at 6,000 miles, August 2019 Crash

On dec 2, 2020 while driving on the freeway at about 45-50 MPH our sunroof exploded causing us to get to the side of the road. The shade was closed which saved us from exploding glass. There were no road hazards, no issues other than a spontaneous exploding of our sunroof. The orlando police dept was summoned and the roadrangers stopped to assist us.

Reported at 6,800 miles, December 2020

My windshield has cracked twice without being struck by an object and without being near another vehicle. Both incidents occurred during normal highway driving. I was not speeding or driving recklessly. Both times required the replacement of the windshield as the crack quickly spread and affected a good portion of the windshield. I am requesting reimbursement for the cost of replacing the windshield (twice). The first incident occurred just a few days after purchase.
