NHTSA Complaint #10165348 — 2005 MERCEDES BENZ C230

PROBLEM STARTS WITH A HESITATION UPON ACCELERATION AND LOSS OF POWER WHILE DRIVING. AFTER SHUTTING ENGINE OFF, THEN UPON STARTING VEHICLE, ENGINE WOULD START TO SHAKE AND STUMBLE. CHECK ENGINE LIGHT WOULD COME ON. VEHICLE ENGINE SOUNDS AS IF IT GOING TO BLOW UP AND HAS NO POWER AND STALLS BECOMES UNDRIVEABLE. IF YOU SHUT ENGINE OFF AGAIN AND RESTART SOMETIMES CAR CAN BE DRIVEN EVEN THOUGH CHECK ENGINE LIGHT REMAINS ON. IT ALWAYS SHOWS THE SAME CODES FOR REPAIR. CAR HAS BEEN TOWED TO DEALER 2 TIMES AND DRIVEN OVER 4 ADDITIONAL TIMES. EACH TIME THE CODE COMES UP AS A COIL DEFECT AND DEALER HAS REPLACED COIL #2 SEVERAL TIMES DUE TO COIL BEING BURNT ALONG WITH CLEANING AND/OR REPLACEMENT OF SPARK PLUGS ONLY TO HAVE THE PROBLEM RECUR WITHIN HOURS OR DAYS. THEY STILL HAVE NOT BEEN ABLE TO CORRECT PROBLEM. DEALER GAVE ME SAME MODEL LOANER VEHICLE WHICH I HAD TO RETURN WITHIN HOURS DUE TO SAME PROBLEMS. *NM
