Limited data — recalls on file
NHTSA has just one complaint on file for the 1990 Mercedes-Benz 500 — too few to judge reliability from owner reports alone — but 2 recall campaigns apply to this year, so any used example should have its VIN checked for completed recall work.

2 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
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.
Defect
LEFT FRONT AND LEFT REAR TIRES MAY HAVE BEEN DAMAGED BY A WORN CHAIN DRIVE OF THE CONVEYOR SYSTEM.
Consequence
DAMAGED OR CUT TIRES COULD FAIL DURING USE AND RESULT IN AN ACCIDENT WITH POSSIBLE INJURIES.
Remedy
REPLACE DAMAGED TIRES WITH TIRES OF THE SAME BRAND NAME.

The record is thin — 1 NHTSA complaint — so owner-report data can't strongly confirm reliability either way, though 2 recalls should be verified as completed.
Yes — NHTSA lists 2 recall campaigns affecting the 1990 Mercedes-Benz 500. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
