“I opened our garage door remotely, as I always do, and pulled into the driveway. As I entered the garage, I attempted to brake but the car continued to roll despite my pressure on the brake pedal. The car ran into the shelving and other items against the garage wall. I have entered our garage in this way many thousands of times, and I am confident I did nothing differently this time.”

It has recently power off on me while driving and restart back up. I took it to the dealership they said it was fine. I took it today.
