Limited data — recalls on file

NCAP overall
1 NHTSA recall campaign on file. Recall repairs are free at franchised dealers.
Defect
ON THE INVOLVED VEHICLES, CORROSION COULD DEVELOP IN THE CRUISE CONTROL SYSTEM SERVO UNIT. CONSEQUENTLY, THE CRUISE CONTROL SYSTEM MAY NOT RESPOND TO ATTEMPTS TO RELEASE IT BY DEPRESSING THE BRAKE PEDAL, BUT COULD BEGIN TO ACCELERATE THE VEHICLE FROM THE SET SPEED (ABOVE APPROXIMATELY 30 MPH).
Remedy
DEALER WILL INSPECT AND, IF NECESSARY, INSTALL A REPLACEMENT ACTUATOR UNIT INSIDE THE PASSENGER COMPARTMENT, FREE OF CHARGE.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 1 recall should be verified as completed.
Yes — NHTSA lists 1 recall campaign affecting the 1973 Mercedes-Benz 450slc. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
Based on NHTSA ODI data through June 2026. Complaints are consumer-reported and unverified. Updated July 5, 2026.
