Filed Dec 13, 2023 · Electrical, Engine · CT

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.

Engine Control Unit failed during warranty after replacement by the Mercedes Benz Dealership. The ECU causes stumbling and cutting out of engine in traffic while driving which can cause an accident putting my self, wife and others at risk. I took the car to the dealership and showed them the stored code of 1596 “The engine off time has an implausible value” (P1026) on the Mercedes Benz Xentry DAS software. Yes: the dealer inspected the car and did a diagnostic. The code was cleared and the dealer claimed there was no code. A CHECK ENGINE LIGHT was present when the problem started approximately 23 months after the ECU was replaced be the dealer with a two year advertised and communicated warranty.

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.

My car ran hot and everything on the inside began to flicker. I pulled over and turned the car off to let it cool. When I turned it back on the check engine light was on with the emfamous p0016 and p0017 codes ad I later found out and it has not run thw same since. If drags, shifts incorrectly, and pulls wrong now.

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.

The car was barely used in about 2 years. Before it had never had a problem, now it can't be taken to emissions because the check engine light is on. It was discovered that this is because the engine wiring harness was deteriorating. Through internet research, I have discovered that mercedes-benz knows about this common problem very well even though they blatantly disregard their customers' safety, claiming they have no such knowledge and requiring customers to pay for it themselves or continue driving an unsafe vehicle. There is no reason other than irresponsible greed that mercedes-benz ignores this problem, and this puts unknowing consumers at serious risk. I am appalled that mercedes-benz has not owned up to their responsibilities and I would be very happy to see action taken to force mercedes-benz to actually value protecting their customers' safety above keeping their pockets lined with money.
