Example complaints

Electrical system: “The instrument cluster LED problem with my 2000 mercedes clk 430 has become more of a problem within the past month. It happens quite frequently now. Whenever I start the vehicle, the gear indicator does not indicate which gear I'm in and the car proceeds in low mode until I pull over and restart it. The safety hazard lies in the fact that I don't check my gear indicator constantly, so if it fails and I don't notice, the low/slow mode that the car automatically shifts into could get me killed on any street where the speed limit is at least 35. …”

NHTSA complaint #10401158, filed 2011-05, 165,456 miles

Transmission and drivetrain: “Shift lever inoperative/ erratic: 2000 CLK430 being driven when transmission refused to shift from low gear, then second gear, and finally not at all! Had vehicle towed to shop, shop found shifter had gone bad. I didn't know the transmission was electronically controlled. $1500 later it now runs out fine. Mileage was 77k.”

NHTSA complaint #10368110, filed 2010-11, 77,000 miles

Engine cooling: “Car engine shut off at traffic light with traffic build up behind me. After an hour of waiting for tow truck, it suddenly started again. Took it to garage which changed the crankshaft sensor for $308.55. Apparently, faulty crankshaft sensor is a known common problem with mercedes clk cars!!”

NHTSA complaint #10217128, filed 2008-02, 76,000 miles

Body and structure: “The front plastic bumper has been designed to be too low to the ground and parking lot wheel bumpers are higher. When parking the 2000 clk model 430, this mismatch causes the plastic bumper to drag along the concrete bumper stop, and because of very weak design of the bumper, it will crack the bumper at its weakest points, causing the bumper to hang loose and become a potential safety hazard. The bumper should be recalled to be replaced with one that is higher from the ground.”
