2006 Mercedes Benz C280

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.

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.

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
