THE ENGINE / FUEL INJECTION WIRING HARNESS OF MY 1993 MERCEDES-BENZ 300E HAS CRACKED INSULATION THROUGHOUT AND IS BEGINNING TO SHORT OUT WITH THE RISK OF CAUSING DANGEROUS ENGINE MALFUNCTION AND EVEN FIRE INSIDE MY ENGINE COMPARTMENT. I HAVE READ MANY REPORTS OF OTHER MERCEDES-BENZ CARS OF THE SAME AGE RANGE HAVING THE EXACT SAME DEFECT. I HAVE BROUGHT IT IN TO MY MECHANIC SEVERAL TIMES BECAUSE OF THE HESITATION AND SHORTING THAT OCCURS - ESPECIALLY WHEN I HAVE THE AC OR HEATER RUNNING AND HAVE SPENT A SIGNIFICANT AMOUNT OF MONEY ON TRYING TO REMEDY IT BY ATTEMPTING TO RE-WRAP THE WIRING BUT IT ONLY AFFORDED ME A TEMPORARY FIX AT BEST. THE ESTIMATE I WAS GIVEN TODAY WAS FOR $1,400 FOR THE WIRING HARNESS AND ANOTHER $700 - $800 FOR THE LABOR COST ASSOCIATED WITH IT'S INSTALL. FROM THE NUMBER OF SIMILAR ANECDOTAL STORIES I HAVE READ ONLINE WHILE RESEARCHING THIS ISSUE, I WONDER WHY MERCEDES BENZ HAS NOT ISSUED A RECALL ON THIS OBVIOUS DESIGN DEFECT. *TR

FUEL INJECTOR HARNESS IS DRY ROTTED AS SEEN IN THE IMAGES ON THIS SITE. I JUST RECENTLY DISCOVERED THAT THERE IS A MAJOR DEFECT WITH THE HARNESS ASSEMBLY DUE TO POOR WORKMANSHIP THIS IS CERTAINLY A MANUFACTURING DEFECT. MERCEDES SHOULD REPLACE THE HARNESS FREE OF CHARGE. *TR

IF ONE OF THE HEADLAMP WIPER ARMS BECOMES MISALIGNED, THE WIPER BALDE CAN LODGE IN THE GROOVE UNDER THE HEADLAMP. IF THE WASHERS ARE ACTIVATED WITH THE WIPER BLADE IN THE MISALIGNED AND LODGED POSITION, THE WASHER PUMP WILL RUN CONTINUOUSLY EXPELLING ALL AVAILABLE FLUID.

Consequence & remedy

Consequence: PUMP OPERATION IN THE ABSENCE OF FLUID CAN CAUSE THE PUMP TO OVERHEAT AND CAUSE A VEHICLE FIRE.

Remedy: DEALERS WILL REPLACE THE HEADLAMP WASHER PUMP ON THESE VEHICLES.

An investigation is not a finding of a defect, and closure does not prove a vehicle is problem-free.
