2006 Mercedes-Benz M-Class ML350 4dr SUV AWD (3.5L 6cyl 7A)
I bought the car in May 05 and returned it within a week due to transmission problems at low speed. When in traffic there is a loud bang when upshifting or downshifting between first and second gears. I received the following comments from the dealer: 1. The vehicle is operating within normal limits 2. The vehicle has to adapt to the driving pattern of the particular driver and has a "memory" that can only be reset if the car is driven from 80mph to 0mph without braking and coming to a complete stop. 3. The vehicle needs software updates. After the 6th return I made a huge stink and they replaced the transmission. So far everything seems to be ok but I no longer have confidence in MB.
