Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

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

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 can't imagine if I had been driving on the freeway at a faster pace. Now I am facing the expense of replacing the belt for the third time(making this the 4th belt), replacing the parts, the cost of labor, and the cost for a rental during the repair time. Mercedes should be honorable and demand a recall on these parts immediately, before serious injuries or death(s) occur. This country does not need to be reminded of the senseless behaviors of the Ford pinto or the most recent, Toyota tragedies. Mercedes can control the outcome of these situations with a simple recall. The cost of the parts in bulk or wholesale would be a very small price compared to the heartache of loosing the quality of life or causing the ultimate result - death!

The engine dies. This is known by Mercedes Benz and is being reported all over. The ignition system needs to be recalled and replaced. Why is NHTSA dragging its feet on this issue. Someone will be injured or killed by this, if it has not already happened.

  • 17,000 miles
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.. if similar happens in the freeway will be death for more than the driver. This is a safety problem.
