THE VEHICLE HAS TURNED OFF BY ITSELF WHILE DRIVING AT VARIOUS SPEEDS.

TO REGAIN POWER, VEHICLE MUST BE SWITCHED TO NEUTRAL, COME TO A COMPLETE STOP, AND KEY NEEDS TO BE CYCLED OFF AND BACK ON. DEALER, MERCEDES BENZ OF WESTMINSTER IN COLORADO HAS NOT BEEN ABLE TO DIAGNOSE THE PROBLEM WITH A GREAT DEGREE OF CERTAINTY, ALTHOUGH THEY THINK IT MAY BE A DEFECTIVE IGNITION SWITCH.
