I had to take the vehicle to the shop for repairs at least every 3-5 months since the day I bought it, which was in 2010. Nearly all of the repairs have been under warranty, it only has less than 75, 000m. In september of this year while I was driving home from work when the car started stalling jerking and shout off. The engine light, esp light and the break light came on. It immediately restarted, the engine light stayed on, while the esp and break light went off. This was a very frighten experience, hoping I won't be hit from behind. I made it to the dealer ship. The car was in the shop for 3wks when I was told that it needed to have a tune up before any other repairs could be done, how this related to the vehicle just stopping in mid drive, is odd.to say the least. 2 days after getting the tune up, it is still in the shop because the engine light is still coming on. I'm feeling uncomfortable about getting behind the wheels again in this vehicle. I expected more out of a mercedes benz with less than 100,000miles

The check engine light came on and soon the car began to have trouble starting. I then began sputtering while driving. Mercedes dealer informed us that the balance shaft had failed and needed to be replaced. This repair would cost close to $6,000. I have seen that this is a very common complaint, almost as if it is to be expected. I also see that there is a class action lawsuit that was filed in 2010. This poses a safety problem when I drive my children, and I cannot afford to pay the repair bill.
