On certain vehicles, a carbon steel check valve spring was mistakenly installed in the dual compartment air reservoir. Usage of carbon steel springs in this application can result in severe corrosion and subsequent failure. If a leak develops in the primary air system, air would not be checked or isolated from the failed system and air would flow from the secondary system and exhaust at the point of leakage resulting in loss of service brakes and application of the emergency spring brakes. If the driver ignores the low air pressure warning light and buzzer and fails to pull off the road - crash

These are NHTSA campaigns for 1983 GMC C6 vehicles sold in the United States. They are not Canadian recalls: NHTSA's VIN lookup has no Canadian data, and a US campaign may have no Canadian counterpart, or one under a different number covering different vehicles. For a vehicle sold in Canada, go by the Transport Canada listing above and GMC's Canadian VIN lookup.
THE FRONT AIR BRAKE HOSE MAY CONTACT THE INNER FENDER ON THE LEFT AND/OR RIGHT SIDES OF SOME TRUCKS. IN SOME INSTANCES, THE BRAKE HOSE MAY RUB THROUGH, RESULTING IN A LOSS OF AIR PRESSURE UPON BRAKE APPLICATION. CONSEQUENCE OF DEFECT: BRAKE HOSE MAY RUB THROUGH CAUSING AIR PRESSURE LOSS WHEN BRAKES ARE APPLIED AND REDUCED BRAKING ABILITY. A REDUCTION OF BRAKING ABILITY AT A TIME WHEN MINIMUM STOPPING DISTANCE IS REQUIRED COULD RESULT IN A VEHICLE CRASH WITHOUT PRIOR WARNING.
INSTALL NEW BRAKE CHAMBER SUPPORT BRACKETS, BRAKE LINE ELBOWS, AND AIR BRAKE HOSES, AS NECESSARY.

THE DUAL AIR RESERVOIRS OF SOME TRUCKS WERE EQUIPPED WITH CARBON STEEL SPRINGS INSTEAD OF STAINLESS STEEL SPRINGS, AS INTENDED. THE CARBON STEEL SPRING IS MORE SUSCEPTIBLE TO RUSTING THAN THE STAINLESS STEEL SPRING. THIS RUSTING COULD CAUSE THE CHECK VALVE TO FAIL, CAUSING TOTAL LOSS OF FRONT AND REAR BRAKES.
THE AIR TANK WILL BE INSPECTED AND, IF NECESSARY, THE AIR VALVE WILL BE REPLACED WITH ONE CONTAINING A STAINLESS STEEL SPRING.

1983 GMC C6 recall questions
Transport Canada lists 3 recalls for the 1983 GMC C6 model year. That counts campaigns naming this model year, not recalls on your vehicle: many cover only a VIN range or production window, and some only vehicles found on inspection. NHTSA lists 2 United States campaigns for the US-market model, shown separately; a US campaign may have no Canadian equivalent.
Enter your VIN in GMC's Canadian recall lookup, or call a GMC dealer with your VIN. In Canada the manufacturer is responsible for showing recall and repair status for each VIN, so its lookup is the authoritative answer. Cardog uses your VIN only to find the model year; the recalls shown here are listed for that model year and are not matched to your VIN.
Not necessarily. NHTSA campaigns cover vehicles sold in the United States, and NHTSA's VIN lookup has no Canadian data. When a defect also affects Canadian vehicles, the manufacturer files a separate notice with Transport Canada, often under a different number and sometimes covering a different set of vehicles. For a Canadian vehicle, go by the Transport Canada listing and GMC's Canadian lookup.
Safety recall repairs are normally done at no charge by an authorised GMC dealer. The manufacturer's notice for each campaign sets out the remedy and any conditions, so confirm with the dealer when you book.
Once GMC's lookup or a dealer confirms a recall applies, book the repair with an authorised GMC dealer and bring your VIN. If the manufacturer's notice says not to drive the vehicle or to park it outside, follow that instruction. Parts can take time, so book early.
Follow the manufacturer's notice for that recall. Most allow normal driving until the repair; some tell owners to stop driving or to park outside until it is fixed. Cardog does not grade recalls by severity: the manufacturer's notice and your dealer are the source.
Manufacturers must notify owners they have on record. If you bought the vehicle used or have moved, update your details with GMC Canada so notices reach you, and check the manufacturer's lookup from time to time.
