I purchased a 2007 mercedes benz c230 sport from a private seller. I soon learned that the vehicle was in limp mode. The dealer said it was the transmission conductor plate. After hours of research, I discovered several owners of a mercedes with the 772.9 transmission have been experiencing the same issue. I ended up paying $2500 for a new tcu from mercedes benz.

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.

Vehicle lost speed on highway. Engine racing but no speed. Pulled over to call for help. No reverse. Had car towed to dealership. Required replacement of transmission electronic control unit. Cost was $1,352.83. Dealer told me it is a common problem. This sounds like a systemic problem with this part and can cause injury or death in certain driving conditions. ...updated 09/28/15 *bf updated 3/29/2016

I was driving my car around 30mph coming to a slow down to make a right hand turn. Made turn and proceeded up a steep hill and my car simply stop pulling/accelerating. This has happened several times. I went out of town to tx for christmas and had the same thing happen. I can't understand why so many complaints and no one has yet to even investigate the problem. The maintenance on these vehicles is expensive. On top of the mb is familiar with this issue and should not be putting this expense off on the owners due to faulty default product that can not even be rebuilt but requires replacing the faulty part with another faulty part. Something needs to be done about this.

Ever since I have purchased my mercedes benz c230- 2007 model, I have been regularly maintaining it as per mercedes recommended maintenance instructions. Recently I experienced an unexpected transmission issue in my car. 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. I have researched online on the federal safety agency.dot.gov, benzworld.org and a few other blog sites where numerous mercedes c230 owners have experienced exactly the same issue. My question is that if this is a known safety related issue and has been reported to mercedes benz USA, llc. Several times, why has mercedes benz not initiated a recall. I hope the company is not waiting for a disaster to happen. I would appreciate if the federal safety agency could please investigate the issue.

Balance shaft premature failure found by cel (check engine light) during diagnostics check at mercedes benz of nashville, tn. The engine has been running well so I was shocked that the first time my check engine light came on that the repair is the balance shaft $5,600 repair. Mbusa refused good will assistance to service director [xxx] on 8/21/13. The service report shows all engine related checks are green/good except for the check engine light reading balance shaft replacement required. I drive over 100 interstate miles daily so the warranty is exceeded quickly. Based on # of claims this is a common problem that will eventually be a safety hazard because the car will fail to accelerate when merging and even stall out complete at any speed. Where is the recall????? Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
