What this recall covers

NHTSA's campaign record, quoted as published

The defect

THE LOW AIR PRESSURE SWITCHES USED ON SOME OF THE INVOLVED VEHICLES HAVE A MANUFACTURING TOLERANCE THAT ISSUES A WARNING ONLY WHEN THE PRESSURE DROPS A FEW POUNDS PER SQUARE INCH BELOW 60 PSI. AS A RESULT, THEY DO NOT COMPLY WITH FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS".

The remedy

IF THE OWNER, UPON RECEIPT OF A POST CARD, INDICATES A COMPLIANCE, THE DEALER WILL REIMBURSE OWNER $5.00 FOR COST OF TEST. IF OWNER INDICATES A NON-COMPLIANCE, THE DEALER WILL SEND TWO REPLACEMENT SWITCHES AND A CHECK FOR $5.00 TO COVER BOTH THE SYSTEM TEST AND SWITCH REPLACEMENT.

Notes

VEHICLE DESCRIPTION: TRUCKS, DRILL RIGS, CRANE CARRIERS, AND SCHOOL BUSES.SYSTEM: SERVICE BRAKES; AIR PRESSURE WARNING SWITCHES.CONSEQUENCES OF DEFECT: IF THE LOW AIR PRESSURE WARNING SWITCH IS NOT ACTIVATEDAT PRECISELY 60 PSI, THE DRIVER WOULD NOT BE FOREWARNED OF POTENTIAL LOSS OFBRAKING ACTION. THIS COULD CONTRIBUTE TO A VEHICLE ACCIDENT.

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.
