“I was driving up to my garage on the side of my house on a clear day, early afternoon. I was traveling about 3 MPH and tried to stop to park in front of the garage door. I depressed the brake pedal and it did not engage, but lurched forward into the garage, crashing into the garage and causing damage to both the garage and the auto.”

NHTSA complaint #11271167, filed 2019-10, 4,500 miles

“I started my car, put it in drive and began to make a u turn out of a parking lot when it suddenly accelerated on its own. I had three turns I had to make in quick succession (u turn, left on public driveway, right on main road) to get on to the main road, and I did this at break neck speed. By the second turn I was giving all my strength to trying to get the brake to work, unsuccessfully (locked), and was fully focussed on turning the car safely to save my life at such high speed. My tires squealed on the third turn and my cell phone flew through the air. …”
