1997 Mercedes-Benz 420 Problems

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.

WELD BROKE AND DISLODGED THE SPRINGS.. *TR

NHTSA ID 10546758 · filed Oct 4, 2013

I AM FILING A COMPLAINT REGARDING AFTER WARRANTY SUPPORT FOR THE ABOVE REFERENCED VEHICLE. THE SPRING SEAT DETACHED FROM THE BODY OF THE AUTOMOBILE CAUSING THE SUSPENSION TO FAIL WHILE THE VEHICLE WAS IN MOTION AT 45 MPH ON A DOWNHILL GRADE. AS THE SUSPENSION DETACHED FROM THE CAR, THE LEFT FRONT SIDE DRAGGED ON THE ROAD CAUSING THE RIGHT REAR TO SLIDE INTO THE OTHER LANE OF TRAFFIC. IMPACT FROM AN APPROACHING VEHICLE WAS NARROWLY ADVERTED. FURTHER, LARGE PIECES OF THE VEHICLE INCLUDING THE COIL SPRING WHERE LEFT IN THE ROAD CAUSING A HAZARD. MY MECHANIC AND THE FACILITY THAT REPAIRED THE VEHICLE HAS STATED THAT THIS IS A COMMON DEFECT IN THE DESIGN OF THIS VEHICLE. FURTHER, A INTERNET SEARCH REVEALS NUMEROUS COMPLAINTS OF THIS FAILURE SPECIFIC TO THIS MODEL. I HAD A DISMISSIVE CONVERSATION WITH MERCEDES BENZ USA. WHO STATED THAT THEY WOULD ONLY INVESTIGATE THE PROBLEM IF THE REPAIR WAS DONE AT AN AUTHORIZED MERCEDES BENZ DEALER. I WOULD ASK THE NTSB TO RE OPEN THIS ONGOING ISSUE WHICH IF LEFT UNADDRESSED COULD CAUSE SERIOUS INJURY OR DEATH. *TR

I RECENTLY HAD A GAS TANK PRESSURE SENSOR REPLACED ON MY 1997 E MODEL MERCEDES. UPON INSPECTION OF THE INTERIOR OF THE GAS TANK, IT WAS DISCOVERED THAT THE RETURN LINES INSIDE THE TANK HAD BECOME DISCONNECTED WHICH COULD RESULT IN LOSS OF TANK PRESSURE, LEAKAGE, AND /OR IMPROPER EMISSION SYSTEM SENSOR READOUTS. THE TANK HAS NOT BEEN DAMAGED DUE TO MPACT SO THE DISCONNECTED LINE APPEARS TO BE A DESIGN OR ENGINEERING DEFECT. IN ADDITION, THE IMPROPER FUNCTIONING OF THE RETURN LINE EQUIPMENT WITHIN THE GAS TANK HAS A MAJOR IMPACT ON GAS MILEAGE. THE DEFECTIVE RETURN LINES REQUIRE THE REPLACEMENT OF THE TOTAL GAS TANK AS A REPAIR MEASURE AT A COST OF OVER $800. I HAVE RETAINED THE DEFECTIVE TANK. PLEASE ADVISE IF YOU NEED ANY ADDITIONAL DETAILS

NHTSA ID 10133880 · filed Aug 23, 2005

THE GAS TANK ON MY MERCEDES BENZ E420 COLLAPSED. IT LOOKED LIKE A GIANT STEPPED ON IT. PRIOR TO THE TANK COLLAPSING THE "CHECK ENGINE" LIGHT CAME ON AND I HAD TO HAVE THE FUEL EVAPORATION SYSTEM REPAIRED. I TOOK THE CAR TO BERBERIAN EUROPEAN MOTORS (A MERCEDES BENZ DEALER) IN STOCKTON CA. FOR REPAIR. THIS FAILURE IS SUPPOSED TO BE COVERED BY MY CALIFORINA EMISSION CONTROL WARRANTY. THE MERCEDES BENZ FACTORY REP. SAID THAT THEY WERE NOT GOING TO FIX THE PROBLEM UNDER THE WARRANTY AND I HAD TO PAY FOR ALL THE REPAIRS MYSELF. MY POINT IN CONTACTING YOU IS THAT A GAS TANK THAT JUST CRUMPELS UP BY ITSELF SEEMS TO BE A SAFETY PROBLEM YOU SHOULD LOOK INTO. THE OTHER QUESTION IS, WHY IS MERCEDES BENZ NOT INTRESTED IN TAKING CARE OF THE PROBLEM UNDER THE EMISSION WARRANTY?

HEADLIGHT WIRING HARNESS IS DISINTEGRATING, AND LOOKS IDENTICAL TO PICTURES SENT TO NHTSA BY OTHER OWNERS AND IS A FIRE HAZARD THAT IS UNDETECTABLE UNTIL SHORTS OR FIRES DEVELOP. THE INSULATION IS LITERALLY FALLING APART, AND THIS CREATES GREAT POTENTIAL FOR UNSAFE OPERATION, SHORTCIRCUITS, BREAKDOWN AND IS A POTENTIAL FIRE HAZARD. *TR
