After fully charged my car, I pulled out of the parking garage and into an available parking stall at work on friday january 24th 2020 at approximately 1:50pm. I let my car cruise into the stall while my foot is covering the brakes. Halfway into the parking stall, the car accelerated on its own. I applied the brakes but did not help. It stopped only when it jumped the front concrete stall with 2 front wheels and hit the trees then rolled back. I then immediately shift the gear to park.
Collision occurred on e denny way in seattle, approx 3:20 pm on a downhill slope in stop-and-go traffic after about 20 minutes of constant brake use to hold back the car. About 2/3 of the way downhill the brakes failed, no resistance whatsoever and the car rolled into the vehicle in front, a distance of about 15 feet. This was a one-off incident and did not recur so far.
Shift to park. Vehicle does not turn off after shifting to park. The car does not detect park mode and driver has to 'jiggle' shift knob.

The manufacturer was not notified of the failure. The failure mileage was approximate 28,995.
