NHTSA complaint #11000826, filed 2017-06, 59,000 miles“The check emissions light for the engine light came up on the dashboard. Without prior warning or other signs the vehicle lost engine power in the middle of the road. The entire electrical power and engine stopped working and the brakes jammed. This causes the vehicle to become unstoppable in the middle of the road causing a safety hazard to the vehicle, driver, passengers and fellow vehicles on the road. The only way to stop the vehicle is somehow use the gears to shift to parking position, turn the engine again on and try to remove the vehicle from the middle of the road.”
