NHTSA Complaint #10748209 — 2006 MERCEDES BENZ C280

I WAS APPROACHING AN EXIT AND THE VEHICLE ENGINE WAS REVVING WITH RPM'S HIGH HOWEVER THERE WAS LITTLE POWER TO MOVE FORWARD. I PULLED THE CAR(COASTING) TO THE SIDE OF THE ROAD TURNED IT OFF AND RESTARTED IT UNABLE TO THINK WHAT ELSE TO DO. ON ANOTHER OCCASION THE SAME THING HAPPENED WITH THE SAME RESULT THIS PROBLEM HAS OCCURRED AT LEAST 4 TIMES.. THIS IS A SAFETY ISSUE BECAUSE IF I HAD BEEN ON A CONGESTED HIGHWAY WITH NO ACCELERATION AND NOWHERE TO PULL OFF THE RESULT WOULD HAVE BEEN AN ACCIDENT. THE ENGINE SHAKES UPON STARTING IT AND THE CHECK ENGINE LIGHT COMES ON AND OFF INTERMITTENTLY. CAUSING ME TO BE UNAWARE OF A REAL PROBLEM. I CANNOT AFFORD TO KEEP TAKING THIS CAR TO CHECK OUT WHY THE CHECK ENGINE LIGHT KEEPS COMING OFF AND ON TO BE INFORMED ITS ANNOYING BUT TO DEAL WITH IT.
