- Electrical systemFire
The battery control module (known as the BCM or BNS) failed, triggering a fire. The incident occurred while the vehicle was parked in a garage and had not been operated for several weeks.

It appears the BCM (Battery Control Module) caught fire and burned a significant portion of the trunk and associated wiring.

I inspected the module after finding that this was a common problem with these cars online. This model of car has been documented to completely catch on fire, even when parked after driving. I have pictures of the burnt board inside my BCM. I am very concerned as it could literally burn my house down. The typical warning for this issue is a red colored warning on the dash LCD display, however I didn't have that warning as my unit is apparently still functioning even though…

PLASTIC PIECE ON GEARSHIFT ASSEMBLY BROKE NOT ALLOWING CAR TO BE PLACED IN GEAR. IS APPARENTLY A PROBLEM WITH 1000'S OF THESE CARS BASED ON INTERNET SEARCH. CONTACTED MERCEDES AND THEY SAID NOT THEIR PROBLEM. THEY CHARGE $1300.00 TO FIX THE PROBLEM.

APPARENTLY LOOKING AT THE INTERNET THIS IS WHAT 1000'S OF PEOPLE HAVE ALREADY DONE. HOW MERCEDES THINKS THIS IS A NOT A SAFETY CONCERN IS BEYOND ME. IT IS AN EXTREMELY DANGEROUS SITUATION TO ALL CHILDREN AS THEY WILL BE ABLE TO PUT CAR INTO GEAR WITH NO SAFETY PRECAUTIONS. I CAN SEE MANY CHILDREN…
