2006 MERCEDES BENZ C280 Engine Problems

The balance shaft sprocket in this car needs to be recalled. It has has known issues since it came out nearly 20 years ago. It can cause your whole engine to blow if not fixed. The fix is often more than the value of the car, around $7000. It is ridiculous. The part was not properly heat treated during manufacture which causes it to fail prematurely at the expense of the owner.

Our car was recalled on 07/03/2008, recall #08V303000, for problems relating to a number of types of mechanical and electrical malfunctions. One was the "(3) OBD SYSTEM MAY CAUSE THE CHECK ENGINE LIGHT TO ILLUMINATE INCORRECTLY; AND (4) THE SPEEDODOMETER MAY BE OUT OF TOLERANCE" This vehicle has had a malfunctioning "CHECK ENGINE LIGHT", that needs to be corrected. It prevents the car from being properly registered, and the warning being on is a distraction to drivers. It has been unresolved by Mercedes and by other mechanics who could not make the proper repair of the "Check Engine Light" issue that was listed in the recall. Mercedes has failed to make the repair, associated with this recall and states that the recall #08V303000 of 07/03/2008 is expired. The car had had recent additional recall work done, and this problem was brought up, but not addressed nor corrected by Mercedes. There has been difficulty in our obtaining Connecticut vehicle emissions approval, and Connecticut registration renewal due to the unaddressed problem by Mercedes. We cannot re-register the vehicle out of Connecticut until this issue is resolved. If we chose the sale of the vehicle, we would have to provide the purchaser a clear and registerable vehicle. Without your assistance in the resolution of this matter that would be impossible to do.

I have a 2006 Mercedes C280 which I purchased almost a year ago with 57,000 miles. It currently has 73,000 miles and is having major mechanical problems which have been life threatening due to when and where they occur. 1. Loss of transmission upon acceleration. If I pull over, turn it off and restart, it will shift fine until it decides it wants to do it again and I either lose the ability to shift, or it goes into limp mode without a Check engine light. This has happened on the freeway, heavy traffic, and have been several close calls. The shop said the codes were for transmission malfunction and valve body malfunction. Just out of nowhere. 2. Check engine light goes on and off repeatedly and The plastic intake manifold needs to be replaced because it is one of the defects Mercedes was sued for on this particular year, model, and engine. All of the oxygen sensors are going out as well and that is just the start. The cost for the part alone is in the $1000 range. My mechanic said the best is yet to come and explained around my current mileage on up is when most of the damage takes place with the valves and whatever else happened with this engine. I'm not sure exactly what all the problems were but he said to take it to the junkyard and was very serious which infuriates me because it's a beautiful car and I couldn't in good conscience sell it to anyone. Mercedes is fully aware of this but not a lot of people benefited from the settlement. The same problems are known by all owners and German mechanics.

We have 71,000 miles on our 2006 Mercedes Benz C280. Before Christmas, the engine light starts going on and the engine starts sounding rough and jerking. We take it into Mercedes Benz and they diagnose a cam shaft issue. It turns out all 2006 Mercedes Benz C280 have the same problem with the same mileage. This car is a safety hazard and needs to be recalled.

WHILE TRYING TO MERGE ON THE HIGHWAY THE CAR RESPONSE SLOWLY WHEN TRYING TO ACCELERATE TO HIGHWAY SPEED THE ENGINE OVER REV'S BUT NO POWER THE SAME HAPPENS WHEN CHANGING LANES. WHILE REVERSING OUT OF A DRIVEWAY THE CAR LOCKED UP BOTH THE ENGINE AND STEERING WHEEL WOULD NOT I HAD TO TURN IN ON AND OFF SEVERAL TIMES AND THE PUT IT BACK IN DRIVE BEFORE I WAS ABLE TO FINALLY REVERSE THIS INCIDENT PLACED MY LIFE IN DANGER BECAUSE WHEN THE CAR LOCKED UP HALF OF IT WAS ON THE DRIVEWAY AND THE OTHER HALF IN THE STREET IMPEDING TRAFFIC. I AM NERVOUS ABOUT DRIVING THIS CAR BECAUSE IT DOESN'T RESPOND AS QUICKLY AS IT SHOULD WHICH COULD CAUSE AN ACCIDENT.

THE CHECK ENGINE LIGHT KEEPS COMING ON AND MY CAR JERKS. IT SOUNDS LIKE THE SAME PROBLEM EVERYONE ELSE IS HAVING WITH THE 2006-2008 C280 MERCEDES BENZ.

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.

CHECK ENGINE LIGHT CAME ON AND WOULD NOT TURN OFF. TOOK VEHICLE TO AN AUTHORIZED MERCEDES DEALERSHIP I WAS TOLD THE ISSUE WAS THE TIMING IN BALANCE SHAFT OF THE ENGINE. ACCORDING TO THE MECHANIC MERCEDES BENZ WAS WELL AWARE OF THE BALANCE SHAFT ISSUE AT THE TIME THE VEHICLE WAS BUILT, BUT THE PROBLEM ONLY SHOWS UP ON SOME OF THE C-CLASS MODELS AND DUE TO THE MILEAGE ON THE MY VEHICLE THERE WAS NOTHING HE COULD DO. IF THIS IS AN ISSUE MERCEDES WAS AWARE I SHOULDN'T HAVE TO PAY 6K TO FIX. THERE SHOULD BE SOMETHING MERCEDES SHOULD DO TO HELP OWNERS WITH THE COST OF REPAIRS. I HAD NO INDICATION THIS WAS A PROBLEM OTHER THAN THE SERVICE LIGHT APPEARING OUT OF NO WHERE TWO MONTHS AFTER MY SERVICE VISIT WHICH WAS TWO MONTHS PRIOR TO THE CHECK ENGINE LIGHT COMING ON. THE MECHANIC TOLD ME I COULD CONTINUE TO DRIVE MY CAR WITH THE ENGINE LIGHT ON IF IT DOESN'T BOTHER ME , HOWEVER I'M AFRAID THE CAR WILL QUIT RUNNING. I WAS PLANNING ON TAKING THE CAR OUT OF TOWN ON VACATION NEXT MONTH I DON'T WANT TO GET STRANDED ON THE ROAD IN THE MIDDLE OF NO WHERE. *TR

ENGINE BEGAN KNOCKING WHILE DRIVING. BALANCE SHAFT MALFUNCTION. CAUSED VEHICLE TO BECOME NON-DRIVABLE. LOCAL DEALER QUOTED 6K TO FIX. CONTACTED MERCEDES BENZ WHICH INDICATED IT WOULD OFFER NO ASSISTANCE IN REPAIR OF THIS PROBLEM. INTERNET RESEARCH SHOWS A CONSISTENT PROBLEM WITH THE YEAR AND C-CLASS VEHICLES. OTHER RESEARCH INDICATES A DEFECT IN THE BALANCE SHAFT USED BY MERCEDES BENZ IN THIS MODEL AND OTHER MODELS. MERCEDES BENZ ISSUED A SERVICE NOTIFICATION ABOUT THIS PROBLEM IN 2008. PROBLEM OCCURRED ON THIS VEHICLE WHILE RELATIVELY CLOSE TO HOME PRIOR TO BEING DRIVEN OUT OF TOWN. HAD THE PROBLEM OCCURRED ON THE ROAD, THE DRIVER AND VEHICLE WOULD HAVE BEEN STRANDED. A NON DEALER MERCEDES MECHANIC STATED THERE WAS AN 8-10% FAILURE RATE ON THE BALANCE SHAFTS IN QUESTION. MERCEDES BENZ NEEDS TO PROVIDE ASSISTANCE TO THE OWNERS TO RESOLVE THE ONES THAT DO FAIL. *TR

AN ENGINE AIR FILTER HOUSING TO MASS AIR FLOW SENSOR SEAL TEAR CAUSED THE ENGINE TO SURGE AND THE CAR TO BUCK FORWARD INSTEAD OF BRAKING WHEN THE BRAKES WERE APPLIED. FAILURE TO BREAK RESULTED IN THIS VEHICLE REAR ENDING ANOTHER VEHICLE. LUCKILY THE VEHICLE SPEED WAS LOW SO NO ONE WAS INJURED OR KILLED. THE SENSORY SYSTEM FAILED TO DETECT THIS ISSUE UNTIL THE TEAR WORSENED AND THE PROBLEMS IT CAUSED WERE BAD ENOUGH AND CONTINUOUS ENOUGH TO TRIGGER THE CHECK ENGINE LIGHT (TOOK APPROXIMATELY 1 MONTH). MERCEDES COULD NOT DIAGNOSE OR FIND THE PROBLEM UNTIL THE CHECK ENGINE LIGHT WENT ON. DURING THAT 1 MONTH PERIOD THE FAILURE OF THE BREAKS TO ENGAGE/ENGINE SURGING/CAR BUCKING ISSUE OCCURRED 2 MORE TIMES. LUCKILY NO ACCIDENTS OR INJURIES RESULTED FROM THESE EVENTS. I HAVE SPOKEN TO MERCEDES US AND MY LOCAL DEALERSHIP ABOUT THIS ISSUE. THEY REFUSE TO ACKNOWLEDGE THIS AS A SAFETY ISSUE OR ACCEPT RESPONSIBILITY FOR IT. *JS
