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
