What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1992 Mercedes-Benz 400E, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
THE CHECK ENGINE LIGHT CAME ON AND BEFORE I COULD PULL OVER THERE WAS SMOKE COMING FROM UNDER THE HOOD. WHEN I OPENED THE HOOD THE AIR CLEANER ASSEMBLY WAS MELTED THROUGH AND SOME FLAME WAS STILL GLOWING IN THE DRIVER SIDE AIR FILTER. THE UPPER ENGINE WIRING HARNESS WAS CHARRED ALONG THE DRIVER SIDE AND THE CONNECTOR TO THE CAM ACTUATOR HAD DISINTEGRATED. AFTER GETTING THE CAR TOWED HOME I FOLLOWED THE HARNESS BACK TO THE AMP CONNECTOR AND ALL OF THE INSULATION ON THE WIRES HAD COMPLETELY DEGRADED TO A POWDER. I ALSO CHECKED THE WIRES ON THE MAF SENSOR AND THE THROTTLE BODY AND FOUND THE SAME CONDITION. THIS IS A MANUFACTURING ISSUE: SUBSTANDARD WIRING INSULATION ON ALL WIRING IN THE ENGINE COMPARTMENT. *TR
1992 MERCEDES BENZ 400E. I AM CONCERNED ABOUT THE SAFETY OF THE WIRING HARNESS ON THIS VEHICLE. INSULATION ON WIRES IS CRACKING AND PEELING OFF EXPOSING WIRES TO OTHER WIRES AND THE ENGINE. I AM CONCERNED ABOUT THIS CAUSING A FIRE. I AM AWARE THAT THIS IS COMMON TO THIS MODEL BECAUSE OF THE COMPOSITION OF THE INSULATION MATERIAL. I DO NOT WANT INJURY TO MYSELF OR OTHERS WHILE DRIVING THIS AUTOMOBILE. *TR
