I bought this car through m-b diplomatic sales program while serving in canada and brought it to the USA on retirement. M-b canada won't help because the car is in the us. M-b USA won't help because I bought the car in canada. M-b corporate in germany simply referred my case back to m-b USA. I am now out of warranty. I want m-b to extend the warranty another 4 years or 50k miles. The car is a disaster.

2 Automatic Transmission problem

Failure Date: 12/26/2004

I leased a 2002 mercedes c32 in December of 2002. Its a documented fact mercedes has been experiencing a high number of defect complaints with this model car. Recently for me was the most serious. . On December 26th 2004, while merging onto a major highway(i95) my car's automatic transmission went into neutral while in the drive position. I had to pull over on the side of the highway put the car into park then back to drive to resolve the problem. I notified mercedes on 12/27, at an appointment I had previously scheduled for other problems. Mercedes after holding the car for a week diagnosed it as a transmission control issue. I had to wait four weeks for a replacement to arrive from germany. In January 2005, while waiting for this part to arrive the same incident occurred while merging onto the same highway the car went into neutral. I again found myself on the side of the road resolving the problem. At the end of January my car was finally fixed by mercedes, I received the car on a Tuesday. On the following Sunday I pulled into a parking spot, put the car into park and turned off the ignition. My car jumped a 10 inch high curb and when I tried to get the ignition it did not respond. I had the car towed to mercedes who diagnosed a broken transmission pin. I drove the car for the next few weeks which the fear of the transmission problem recurring. I eventually stopped driving the car and contacted mercedes. I asked them to consider taking the car back, its has 8 months remaining on a 3 year lease. They in turn took the car for a week drove it for 60 miles then diagnosed the problem has been resolved. In my right mind I cannot drive this vehicle for fear of killing myself and others. Mercedes has washed their hands of this situation.
