“Transmission at 60000 started making noise. My mechanic diagnosed as transmission rear drive shaft bearing. Looking on internet, many people had same issue at even lower mileage. And mercedes does not make just bearing, the entire transmission needs replaced.used transmissions are doing same thing. I think it is time to issue a recall”

“Parked car left for an hour came back and tried to start vehicle and it would not start dealership said it was the eis (electronic ignition switch) and charged me $1900 to fix it, also before I took it in for that repair the sunroof would not work properly and rear right brake light went out they fixed that under recall free after that my sunroof worked fine. Now my serpentine belt broke and shredded while I was driving looked in my engine and the belt was all over engine in pieces.”

“Transfer case reseal. I have a 2008 C300 I bought with 56k miles on it, I had to have the wheel bearings replaced immediately. When this service took place, I was informed that I need to have my transfer case resealed and the cam shaft magnets replaced. This car has such low miles on it. I do not understand how this is needed at this time. I have seen on many boards, this is a common problem. Why hasn't mb recalled this yet? It appears the 2008 model is plagued with problems as I have had to replace the steering lock as well as it failed. Again, common problem and not recall. …”

“The serpentine belt shredded for the third time after having it replaced twice within four weeks. As of 4/15/2015 this car will have its 4th belt installed. Clearly the tensioner and pulley(s) are majorly defected. Each time these incidents were life threatening for me and my daughters. We were simply blessed not have been hit by other drivers when the car lost total control with no steering power. Each time of the car's malfunction, I was surrounded by other drivers, moving with the steady flow of traffic.these are serious issues. …”

“I purchased a new 2008 mercedes benz C300, on 8/16/2009, upon stating the car engine started to race so fast reached 7000 RPM within less than 5 seconds. I turned the engine off waited 2,to 3 minutes I started the engine again same thing happened . I waited 4 to 5 minutes started the engine every thing back to normal. Dealer checked the computer hard disk and could not find that incident. Knowing if power surge or computer glitch happens will not be recorded by the same computer.. Same thing happened before when I had 4000 miles.. …”
