Fuel/propulsion system

118 reports3 crashes2 fires
“While driving the vehicle at 60 mph in traffic, all propulsion was lost and the car displayed "stop safely now." Fortunately, I had enough momentum to drift to the side of the road, but this was a very unsafe situation. The vehicle was towed to a dealership where they diagnosed the high voltage battery to have experienced a sudden failure. The vehicle has approximately 60k miles, and searching online indicates that this is a common problem at this mileage. The replacement batteries are jow only built to order, so the vehicle has now been out of service for over 2 months while waiting on a replacement battery.”
