Selected complaints filed with NHTSA by 2007 Mercedes-Benz C230 owners, lightly cleaned up (personal details are redacted by NHTSA).
On several occasions I have experienced my vehicle going into limp mode due to the same transmission problem that everyone else seems to be having. It has happened when pulling away from an intersection, trying to overtake a slower vehicle, trying to get up to speed entering the interstate, but nothing particular seems to trigger it. Fortunately, I have always been able to pull the vehicle to the side of the road, shift to park, and shut the vehicle off and restart it, which would fix the problem. Until now. After the last time it happened, the vehicle will not reset. It is stuck in what appears to be second gear. I can't believe that Mercedes Benz has not been forced to recall the vehicles equipped with the 722.9 transmission. I have researched this on the internet and it appears to be a problem world wide. …
My vehicle became stuck on one gear as I entered the freeway. I had my kids with me and I had to pull over the shoulder. After turning it off and on again, it reset itself. This has happened 4 times now. Now its happening on stop lights as I try to accelerate, it feels its dragging and cars behind me are honking at me to move out of the way. It is unsafe and I cant afford to fix it or buy another one. I researched and found much more people are having this problem. Why has no one done anything about this issue? My wife drives this car and I am not sure if she will respond in the same fashion as I did when presented with this dangerous event if it occurs. I wanted someone with some clout to know about this just in case a disaster occurs I know who to go after. Please make Mercedes Benz responsible and fix this free of charge. …
2016 I took my 2007 Mercedes Benz C230, into Mercedes Benz to see why the check engine light was on. My car was purchased with 37K miles on it at the time I purchased it. How could such a major issue, arise in car so early in it's life. Mercedes stated, that they make the best quality of cars in the world! They stand by this slogan. However, why would such a major issue occur in a car with such low miles/usage? As I understand it, matters of this magnitude ideally does not occur in such a quality car, let alone in the cars infant stage or would likely happen at all! I was told sometime ago that Mercedes knew of this issue. I also searched the internet and discovered so many owners are having the same issue around the world. Mercedes has refused to correct, its defect it was well aware of! Who allows Mercedes Benz, the platform to see these cars to consumers, without resolving the issue. …
Transmission will not shift, goes into limp mode. Turn the car off, wait a couple minutes, restart the car and it drives fine. This first happened May 2015 with 66,000 miles. Our mechanic told us this is a very common Mercedes transmission failure. We choose to replace the fluid, and it did seem to help. Now we have 79,500 miles and it goes into limp mode once a week. The fluid was supposed to last 100,000 miles. Our mechanic said the fluid we changed was clean. This is a very dangerous situation, a known Mercedes defect with the transmission electronics. The next step if we decide to keep the car is to replace the transmission conductor plate. Never again will I buy a Mercedes. This car has been babied by my wife, and has less than 100,000 in 9 years. Any japanese automobile would have easily provided double the life before failure. …
The 2007 Mercedes Benz C230 with 68,000 miles has after coming to a stop - I would place foot on accelerator and the vehicle not shift out of low gear. It would barely move. On other occasions the vehicle would not go and the vehicle RPM's would rev beyond normal RPM's. This could happen also at this could happen also at any speed I was entering the freeway, as I was trying to enter into traffic trying to accelerate my car would not pick up speed, and the car lost acceleration on a major highway while driving at a speed of 65 MPH. I had to pull over to the shoulder and shut off the engine for a few minutes. Only after restarting the engine, the acceleration improved. I have experienced this issue three times now and am concerned about me and my family's safety, why has Mercedes Benz not initiated a recall. I hope the company is not waiting for a disaster to happen. …
The car stays in first gear and I have to stop and pull over. Put it in park and it jerks very badly going it to park. Then I turn it off, and back on. Then everything goes back to normal, until it happens again. So many people have this issue and there is no recall. What are they waiting for. There is 113 complaints on this car and almost none are from the only recall they have actually issued. This happens on a red light. It happens on the high way. In reverse. I wish I never bought this car. Some people paid 1500 dollars to fix it. I thought Mercedes meant high quality. At least they can admit their mistake and fix it for the people suffering before someone dies. The car has 94000 miles. My Honda went to 200,000 with out issues.
The car stays in first gear and I have to stop and pull over. Put it in park and it jerks very badly going into park. Then I pull off the road, stop, turn it off and back on. Then everything goes back to normal, until it happens again. I read on-line of many people having this same issue and there is no recall. Imo this is a safety issue and I do not feel comfortable with loved ones in this car. My dealership is reapiring the transmission as I write for $1400+. I thought Mercedes meant high quality/reliability. At least they can admit their mistake and fix it for the people suffering before someone dies. My car only has 63,000 miles and has been serviced by the dealership iaw service manual.
