This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
While driving, my son was using the heated seat function and noticed a burning smell, the driver side seat was smoking, which burned a hole in the left hand side of the seat back and also burned a hole in the back of my sons sweatshirt.
Driver's side seat back, left bolster, started to smoke and burned a dime size hole in the leather seat cover. Driver's seat heat was on at the time. Turning the seat heat off seems to have solved the problem temporarily. Suspect short in seat heat wiring. Potential fire hazard!
Seat control module failure. 2 modules per car, 1 for passenger seat, and 1 for driver seat fail. The defective seat control module unit will deplete the cars battery overnight resulting in a no-start condition the following day. A new battery, or a jump start, will get the car going again. The common immediate resolution is to unplug the seat control module which would impact the seats ability to respond in an accident. The replacement part and diagnosis from mb dealer is approx $700/ module. This is a huge liability for Mercedes owners and the repair should be investigated for seat function safety. I understand the part number has been updated, which I believe is an admission by Mercedes that the original part is defective.
My driver's seat warmer caught fire yesterday while in use. It started with smoke coming from the backrest portion of the seat after switching the heater on, and then began to flame. I turned off the warmer switch and put out the fire. I now have a hole in the backrest where the fire started.
