I have experienced seemingly unending electronic failure issues with only 5,000 miles on vehicle:
Failure to go into sleep mode causing dead battery;towed to dealer 200 mi. away, MB refused to return to my location;
When vehicle is locked, one door, although locked, causes alarm and will open if handle is touched, even if EasyGo key is not present;
Adaptive High Beam headlight failure;
Rear tailgate opens with driver door occasionally;
When spraying the car with water, while washing, doors lock and unlock continually if you have key in pocket; circuit board replaced, issue continues- another appt. made
Where is the quality control?
Great handling, rides like a sedan.
Seats 7 easily.
Quality control needs to be improved.
Dealer/MB support is lacking when not in major city close to a dealer.
