Limited data — recalls on file

NCAP overall
2 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
VEHICLES HAVE A PRIMARY AND A RESERVE BRAKING SYSTEM. IF THE PRIMARY BRAKE SYSTEM BOOSTER FAILS, UNDER SOME CIRCUMSTANCES THE RESERVE SYSTEM MAY ALSO MALFUNCTION AND BRAKING ABILITY WILL BE IMPAIRED.
Remedy
DEALER WILL INSTALL A NEW RESERVE BRAKE CONTROL MODULE AT NO COST TO OWNER.
Defect
UNWANTED AIR IS BEING DRAWN INTO THE BRAKE SYSTEM WHEN BRAKE PEDAL IS RELEASED. THIS IS DUE TO THE USE OF THE BENDIX MASTER CYLINDER IN COMBINATION WITH THE BENDIX HYDROVAC.
Remedy
DEALER WILL CHECK TO SEE IF VEHICLE IS EQUIPPED WITH A BENDIX MASTER CYLINDER. IF SO, DEALER WILL INSTALL A TUBE AND HOSE ASSEMBLY AND REPAIR BRAKE SYSTEM. IF NEEDED, A NEW WAGNER MASTER CYLINDER WILL BE INSTALLED.
The record is thin — 0 NHTSA complaints — 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 1983 GMC P6t042. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
