What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
While vehicle was in drive with foot on brake pedal, the vehicle surged foward, hit a wall in garage, causing passenger's side air bag to deploy, while driver's side air bag did not deploy. Please provide details.
Abs brakes; failure on the brake system caused the consumer to have an accident, electrical short or shock.
1994 c280 mercedes caught fire after being driven for about 15 minutes. Mercedes was destroyed and car next to it totaled as well. House damaged (cars were in driveway). Fire inspector said fire started under hood, appears it was probably the wiring harness.
Engine wiring harness has brittle insulation; has hundreds of cracks; insulation is falling off of wires; is short circuiting, motor is running rough; missing some; sounds like its not running on all cylinders. Wiring harness is heating where it is short circuiting. I have seen some smoking; was on fire once so far.
The car started to smoke due to exposed wires touching and shorted out a.c. The car cannot be driven now until wiring harness is replaced due to risk of fire. This car is a death trap - just glad I caught it when I did.
My 1994 mercedes benz would stop in traffic for no reason.
This is an intermittent problem that happens when slowing down for a stop light and applying pressure to the brake pedal, the vehicle will suddenly accelerate forward for a second. Driver has to press harder on the brake pedal for vehicle to stop.
While driving experienced abs failure, upon braking pedal went to floor, brakes seemed ineffective in stopping, causing extended stopping distance.
