NCAP overall
1 NHTSA recall campaign on file. Recall repairs are free at franchised dealers.
Defect
IN CERTAIN HIGH SALT AREAS, THE IDLER ARM IS EXPOSED TO ROAD SALT WHICH CAUSES THE DUST SEAL TO DETERIORATE RESULTING IN IDLER ARM PIN CORROSION. THIS CAUSES THE PIN TO FREEZE AND BREAK. CONSEQUENCE OF DEFECT: A BROKEN IDLER ARM PIN COULD RESULT IN LOSS OF STEERING CONTROL AND MAY CAUSE AN ACCIDENT.
Remedy
REPLACE PIN WITH ONE OF IMPROVED CORROSION RESISTANT QUALITY.
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 1977 Mazda GLC. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
