The short answer

NHTSA received TRANSPORTATION MFG. CORP.’s report on Aug 15, 1979. Copied from NHTSA on Oct 23, 2026.

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

The notice gives no hazard in a field of its own.

THE INVOLVED VEHICLES HAVE THE FOLLOWING NON-COMPLIANCES: THE LOW AIR WARNING SIGNAL MAY NOT ACTIVATE UNTIL THE SERVICE RESERVOIR PRESSURE IS BELOW 60 PSI.

IN ADDITION, THE BRAKE RELEASE TIME MAY EXCEED 0.55 SECONDS AT THE RIGHT FRONT WHEEL, WHICH CONSTITUTES A NON-COMPLIANCE TO FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, “AIR BRAKE SYSTEMS”.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • This recall names only model years before 2015, which have no pages here. Your VIN, at NHTSA, says which recalls are open on a vehicle.
  • How many have been returned or fixed isn’t in the notice.
