Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

Experienced some issues shifting into 1 or second gear. Then suddenly the engine stopped during driving and would not start. They car is still at MotorWerk in Barrington and we have no idea what the damage is going to be.

The transmission failed completely. It sound like a major mechanical interference in the transmission and then the vehicle would no longer shift into any gear except park. The dealer diagnosed it as the electrical contact plate and said they would pay for the part and i would pay for the labor $650. After replacing the part the realized it was an internal issue and the transmission needs to be replaced. Still waiting to hear the final solution from the dealer and whether Mercedes Benz will cover this vehicle since it only has 65K on it and it is only 3 months out of warranty.
