Owner report 10872438 · 2016-06-03 (June 3, 2016)
CAR STALLS CONSTANTLY, LOOSE FUEL CAP WARNING COMES ON, CHECK ENGINE LIGHT COMES ON. I HAVE REPLACED THE FUEL CAP, CHECKED VEHICLE CODES, BUT CANNOT GET THE ISSUE IDENTIFIED. A VEHICLE STALLING LIKE THIS IS A TREMENDOUS SAFETY HAZARD, AND IT MAY BE POSSIBLE THAT THERE IS AN ISSUE WITH THE FUEL DELIVERY SYSTEM IN THIS YEAR MODEL, JUST AS THERE WAS WITH THE 2011-2012 MODELS WHICH RESULTED IN A RECALL. THIS HAPPENS BOTH WHEN THE VEHICLE IS STATIONARY AND IN MOTION.

FIRST THERE WAS NO POWER TO THE CAR SO WE REPLACED THE BATTERY. THEN THE CAR WAS RUNNING AND SHUT OFF ONE DAY AND WOULD NOT RESTART. THE VEHICLE WAS STATIONARY WHEN IT WOULD NOT RESTART. WE HAD IT TOWED TO MERCEDES DEALER. THEY ARE STATING IT THE POWER ELECTRONICS MODULE. THERE ARE TWO RECALLS RELATED TO THIS PART BUT WHEN CHECKING THE VIN OURS IS NOT PART OF THEM. THAT IS IMPOSSIBLE. THE MERCEDES DEALER EVEN STATED THERE WERE ISSUES WITH THIS PART THAT'S WHY MERCEDES ONLY MADE THESE CARS FOR TWO YEARS. PLEASE SEE CAMPAIGN NO. 2012080004. *TR
