Transmission leaks so car starts shifting hard jerking learching. Mechanic says it is a torque converter seal that leaks so needs to be replaced. But have to pull the engine & transmission out to split so the labor is 22-23 hours labor when the part is only like $23 so the repair because of the labor would be about $2200 which we can't afford. The mechanic found so many same vehicles with this problem that there should be a recall. But of course the dealer won't report because they don't want to have to make this expensive repair to so many vehicles. While driving fast or slow accelerating breaking to slow down, taking off at a stop sign stop light going in reverse etc it hesitates to go into gear. Keeps happening multiple times a year we have to keep checking changing the transmission fluid & getting it topped off.

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. I now have a seatbelt sensor that faulty. All of this before I have even hit 100K. My 2001 ml is well over 200K and I have never had these issues with the ml.

Issue with cam gears. Mercedes has know about this issue for many many years. There should be a recall on this issue. Car is unsafe with this problem and costs about $8000 to fix. From the online class action lawsuit from 2013 "the engines are equipped with defective gears in their balance shafts or with defective idle gears. These defective gears wear out prematurely, excessively, and without warning, causing the vehicle to malfunction, the 'check engine light' to remain illuminated, and the vehicle to misfire and/or stop driving."

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

Now my serpentine belt broke and shredded while I was driving looked in my engine and the belt was all over engine in pieces.

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.

Car would not start or shift gears. Battery was found to be fully charged. Gears and steering completely locked out. No dash board lighting. Mercedes Benz dispatched but could not jump start. Towing only after forcing cover off gear shifter and overriding gears to put vehicle in neutral. 69K 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.
