Example complaints

Transmission and drivetrain: “Highway driving, cruise control set. Cruise control beeped, disengaged. Car continued to drive normally until I had to stop for a light. When light changed to green, the car would barely move - had no power, even though the rpms showed the engine running. Fortunately, I was near a gas station and was able to get off the road. This could have been very hazardous had it occurred in heavy traffic.... I pulled off the road, restarted the car and everything seemed to be fine. …”

NHTSA complaint #11113264, filed 2018-07, 79,102 miles

Engine: “While trying to merge into highway traffic (i94 in michigan) I pressed the accelerator to gain speed to merge only to find that the engine lacked any power, the rpms rose slowly but there was little to no acceleration. I was told (by mercedes dealer) that this is a known issue and in this case it almost caused my death. If this is a know issue why are our lives being put at risk because of a poorly designed part?”

NHTSA complaint #10870938, filed 2016-05, 213,000 miles

Fuel system: “I took my 2007 mercedes benz blutech to the dealer for the once a year b service. While they were doing the service, they noticed diesel fuel leaking behind the left rear tire. I had them perform an inspection for $135 and they determined that fuel was leaking out of the left fuel level sender area with no visual damage. They recommended replacing left tank seal and inspecting tank and sensor for cracks for $368. Before having the work performed , I went on the internet and found others having the same problem with their mercedes with NHTSA action #pe12001. …”

NHTSA complaint #10482449, filed 2012-10, 21,458 miles

Electrical system: “The insulation on the wiring harnesses for the headlights has completely disintegrated and is sitting in a pile of bits on the bottom of the headlight assembly, literally leaving completely bare wires leading up to the headlamp sockets. If these wires were to touch and short out it could result in complete loss of headlights at night at highway speed. This defect was discovered when attempting to replace a burned out low beam headlight bulb. …”
