Recall campaignsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

SERVICE BRAKES, AIR:SUPPLY

Jan 16, 1978
527 units potentially affected
The defect: THE INVOLVED VEHICLES MAY NOT COMPLY WITH FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "MODULATED EMERGENCY BRAKING". THE "O" RINGS IN THE SHUTTLE VALVE MAY DEVELOP SLIGHT LEAKS IN COLD WEATHER. IN ADDITION, NEOPRENE WASHERS USED ON THESE "O" RINGS MAY EVENTUALLY EXPAND OR PUCKER IN COLD CLIMATES, MAKING IT POSSIBLE FOR THE SHUTTLE PISTON TO BECOME TRAPPED BY THE INNER-CIRCUMFERENCES OF THE WASHERS. THIS WOULD FORCE THE EMERGENCY BRAKES TO THE "ON" POSITION AND WOULD PREVENT THEM FROM BEING RELEASED.
The remedy: THE DEALER WILL REPLACE THE TWO NEOPRENE WASHERS WITH GLASS FILLED TEFLON WASHERS THAT WILL NOT BE AFFECTED BY COLD CLIMATES.

What a recall is

Safety recall
A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
Safety investigation
NHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
Manufacturer communication
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
