Limited data — recalls on file
NHTSA has just 0 complaints on file for the 1980 Mack Mr600 — 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.

NCAP overall
1 NHTSA recall campaign on file. Recall repairs are free at franchised dealers.
Defect
DUE TO THE HIGH STRAIN WITHIN THE FAN BLADES OF THE COOLING FAN, CRACKS MAY DEVELOP IN THE FAN. THESE CRACKS MAY LEAD TO COMPLETE FRACTURE OF THE COOLING FAN, PROPELLING THE FAN AND PIECES OF THE FAN BLADES OUTSIDE THE FAN SHROUD.
Remedy
THE DEALER WILL INSTALL COOLING FANS WITH IMPROVED FAN BLADES ON ALL AFFECTED VEHICLES FREE OF CHARGE TO OWNER.
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 1980 Mack Mr600. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
