Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

ASR LIGHT CAME ON, CAME UP TO A RED LIGHT ON A HILL, STOPPED , LIGHT TURNED GREEN AND WHEN I ATTEMPTED TO ACCELERATE THE CAR HAD ALMOST NO POWER AND HAD A VERY HARD TIME GETTING THROUGH THE LIGHT. THE CAR WAS TAKEN TO THE REPAIR SHOP WHERE THEY WERE UNABLE TO DIAGNOSE THE PROBLEM. THE TESTER WAS UNABLE TO COMMUNICATE WITH THE CONTROL MODULE. I FINALLY FOUND A REPAIR SHOP THAT KNEW ABOUT THIS CAR HAVING A KNOWN PROBLEM. WHEN HE SHOWED ME THE WIRING IT HAD CRACKED BROKEN MISSING INSULATION ON THE ALL THE WIRES. HE SAID THAT SINCE THE WIRING WAS MISSING IT'S INSULATION IT WAS SHORTING OUT. THE E T A WHICH CAUSED THE LIMP MODE. *TR

CHECK ENGINE LIGHT ON DASHBOARD,IDLE ROUGH,STALLING OF CAR. I CHECKED THE ENGINE HARNESS CONNECTOR TO THE AIR MASS METER AND GENTLY MOVED THE WIRES. THE OUTSIDE INSULATION BEGAN TO SMOKE, THEN MELTED FROM THE HEAT. I QUICKLY TURNED OFF THE CAR'S ENGINE AND CHECKED THE DAMAGE. THE INSULATION COVERING THE 4 WIRES INSIDE OF THE HARNESS HAD TOTALLY DISINTEGRATED, THUS CAUSING SHORT CIRCUITS IN THE HARNESS. THE HEAT GENERATED ACTUALLY MELTED THE OUTSIDE COVERING OF THE WIRES BOTH AT THE AIR MASS METER CONNECTOR AND UNDERNEATH THE MAIN ENGINE COMPUTER(ECU). I HAD THE CAR TOWED TO THE LOCAL MB DEALER AND THEY SAID THAT THE WHOLE BODY WIRING HARNESS WAS DESTROYED AND HAD TO BE REPLACED AT A COST OF $1250 PLUS $600 FOR THE HARNESS. MB SAID IT WAS NORMAL WEAR AND TEAR AND OFFERED NO ASSISTANCE. I FEEL THAT THE HARNESSES ON MY 1995 SL320 WERE MADE FROM SUBSTANDARD MATERIALS AND THUS DISINTEGRATED PREMATURELY PUTTING MYSELF AT RISK FROM A POSSIBLE CAR FIRE. I STILL HAVE THE HARNESS IF YOU WOULD LIKE TO INSPECT IT. ANOTHER HARNESS, THE ENGINE WIRING HARNESS WAS ALSO FOUND TO BE DEFECTIVE, CAUSING SHORT CIRCUITS, AND WAS REPLACED BY MB UNDER WARRANTY IN 1998. SO FAR I HAVE REPLACED 4 DIFFERENT WIRING HARNESS ON MY CAR, ALL SHOWING THE SAME DECOMPOSITION OF THE WIRING INSULATION. *NM
