Limited data — recalls on file

NCAP overall
1 NHTSA recall campaign on file. Recall repairs are free at franchised dealers.
Defect
A MISROUTING OF THE POSITIVE BATTERY CABLE MAY EXIST. THIS MAY CAUSE DAMAGE TO THE POSITIVE BATTERY CABLE INSULATION DUE TO RUBBING ON THE RIGHT FRONT METAL BRAKE TUBE. SHOULD THIS OCCUR, THE WIRE IN THE CABLE MAY CONTACT AND DAMAGE THE BRAKE TUBE, CAUSING LOSS OF BRAKE FLUID.
Remedy
DEALER WILL INSPECT ALL VEHICLES FOR MISROUTING OF THE POSITIVE BATTERY CABLE AND ABRASIVE DAMAGE TO THE CABLE INSULATION. IF NECESSARY, BATTERY CABLE WILL BE REPLACED AT NO 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 GMC M6500. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
