NHTSA Complaint #10627249 — 2013 MERCEDES-BENZ C250

2014-08-04: ENGINE LIGHT CAME ON, VEHICLE WOULD NOT ACCELERATE PAST 80 KM/H AND THE ENGINE SHUT OFF - DRIVING IN TRAFFIC. 2014-08-05: BROUGHT VEHICLE TO 550 TERMINAL AVENUE. THEY SAID IT WAS JUST THE FAULT-PUMP AND THAT IT WAS SAFE TO DRIVE. THEY ADVISED ME THAT THEY HAD TO ORDER THE PART FROM GERMANY. VEHICLE WAS LATER RETURNED THE SAME DAY. (23505 KM) 2014-08-06: THE VEHICLE ENGINE SHUT DOWN WHILE DRIVING OUT THE DRIVE WAY, SO I HAD IT TOWED TO 550 TERMINAL AVENUE. (23514 KM). THEY REPLACED A THROTTLE ACTUATOR. 2014-08-12: VEHICLE WAS READY FOR PICK UP. VEHICLE WOULD NOT START. BATTERY REPLACED. 2014-08-14: PICKED UP VEHICLE. THEN EXPERIENCED A LOW ACCELERATING AFTER BRAKING. WENT WITH THE FOREMAN FOR A ROAD TEST AND HE AGREED THAT THERE WAS A DELAY WHEN ACCELERATING AND THAT IT FELT LIKE ITS GOING TO STALL WHILE IN "DRIVE". 2014-08-20: THEY SAID IT WAS CAUSED BY 13 % ETHANOL IN FUEL/ SOFTWARE. THERE'S A PINGING SOUND. BUT I BUY THE SAME GAS EVERY TIME 94 OCTANE FROM CHEVRON. I HAD A VERBAL AGREEMENT SAYING THAT MY CAR WAS SAFE TO DRIVE AND FOR ME TO COME BACK TO MERCEDES BENZ WITH A NEW TANK OF GASOLINE TO SEE IF I WOULD STILL HAVE THE SAME ISSUES AS IT WAS STATED THAT THE ISSUE MAY HAVE BEEN CAUSE BY USING GAS WITH 13% ETHANOL/SOFTWARE. *TR
