The contact owns a 2018 Porsche Carrera. The contact stated while driving at 50MPH when the contact attempted to turn off their headlight switch on the vehicle but instead accidentally hit the ignition switch which caused the engine to shut off and the vehicle to coast on its own. The contact was able to veer to the side of the road and restart the vehicle and continue to drive to their residence. The contact concern was that headlight and ignition switch on the vehicle were so close together that its manufacturer design an error with the vehicle which could lead into an accident while driving the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 12,000.
