While parking my vehicle in the garage, I pressed the P (park) button on my center console and proceeded to exit my vehicle. As I was exiting, the car began to roll backwards. I was knocked to the ground by the open driverâs door, unable to reenter the vehicle. The vehicle began rolling causing me injury to my legs, elbow and feet because I was essentially trapped under the side of the vehicle as it was moving. The vehicle continued to roll. Hitting items on my garage, including my second vehicle parked in the driveway, before coming to a stop by hitting a neighboring chain link fence. The vehicle sustained damage to driverâs door, rear end, and front left panel. Iâve looked online and have seen several forums of similar issues with the Volvo P button not engaging, and vehicles rolling/lurching unexpectedly.
