Verdict · NHTSA data
Limited data — recalls on file
NHTSA has just 24 complaints on file for the 1993 Mercedes-Benz 500 — too few to judge reliability from owner reports alone — but one recall campaign applies to this year, so any used example should have its VIN checked for completed recall work. Reports tied to this model year include one death and 1 injuries, per the complaint records themselves.

Defect
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
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.
