Example complaints
Electrical system: “Recently bought car. Wiring harness had already been replaced, but computer has not acted correctly since the wiring shorted out due to faulty insulation. Throwing faults and no idle. Surges forward or backwards on its own. While backing it out of garage, it surged backwards so fast the brakes would not hold. Hit tractor parked in driveway before getting it stopped. Broke rear bumper cover. I have older vehicles (1974 chevy) (1990 chevy pickup) with absolutely no wiring problems. Now I have a really nice 1994 E320 that is junk because I can't afford the $12 - $1500 to repair it. …”
NHTSA complaint #10543216, filed 2013-09, 167,000 milesVehicle speed control: “Started the car at work and it was running rough had no acceleration. Went into limp home mode and I was able to get home. My husband is a mechanic and found the wiring harness was deteriorating, flaking and falling apart exposing all the wires. The car would no long even start. I called mercedes to see if they would help with the cost of the part replacement. They denied any problem with the product and would not assist in any repair. I logged a complaint with them under my name and have tried many times to get assistance with the repair. …”
NHTSA complaint #10456513, filed 2012-04Engine: “Under normal driving condition engine started revving up to about 3500 RPM as if I pressed the accelerator pedal. Freaky experience but luckily the road wasn't too busy. I slowed down to the side of the road (was driving in portland oregon inner city area) by pressing the brakes and flipping the car into neutral but the engine kept revving up around 3000-4000rpm. When I turned the engine off and started it again, it wasn't so bad but the engine was still revving up and down by itself between about 750 and 2000rpm. …”
