NHTSA Complaint #11624124 — 2013 TESLA MODEL S

While driving on the freeway at 70 MPH with 39 miles of range left, the vehicle abruptly slowed down to 20 MPH...cars behind us almost hit us due to the car slowing down despite me accelerating. We pulled to the right shoulder, rest the car and then was only able to go up to 20MPH...range still said 39 miles. Shortly after the car stopped, there was a warning displayed, and the car turned off and could no longer turn back on. I believe the battery failed. The car was towed to Tesla Irvine Barranca Service center and diagnostics confirmed the battery needed replacement. I traded in the car for a new vehicle. Safety of the driver, passengers, and the around us on the freeway were all at risk and we were lucky to avoid any issues. All Tesla told me was the battery died There was a warning that appeared when the car slowed down to 20mph...stating the car was no longer able to be driven
