Does this affect my vehicle?
This recall covers vehicles built between August 1978 and October 1978. If yours was built outside that window, it is not part of this recall.
- 1979 GMC N9F064Built August 1978 to October 1978
What the defect is
The involved vehicles fail to meet federal motor vehicle safety standard no. 121, "air brake systems", in regard to incorrect plumbing in the low air pressure warning system. As a result, a low air pressure condition in the rear brake air supply will not actuate the warning system. The audible alarm would not function and the driver would not be warned of a brake malfunction.
What gets fixed
THE LOW AIR PRESSURE WARNING SYSTEM WILL BE INSPECTED AND CORRECTED, IF NECESSARY, WITHOUT CHARGE.

Your rights
A safety recall repair is free. Under US federal law the manufacturer must fix a safety defect at no cost to you — no charge for parts, labor or diagnosis — whether or not you are the original owner. A dealer cannot charge you for recall work, and cannot require you to have bought the vehicle from them.
That entitlement is not unlimited. It applies where the vehicle was first sold less than 15 years before the recall was announced — 5 years for tires. Past that a manufacturer may still do the repair free of charge, and many do, but they are no longer obliged to. This recall was reported on 13 April 1979.
To arrange the repair, contact any franchised dealer for the brand. If a dealer refuses the work or tries to charge for it, you can report that to NHTSA at nhtsa.gov/recalls or on 1-888-327-4236.

Everything on this page — the models listed, the build dates and the repair figures — comes from the manufacturer's filing to NHTSA and describes the vehicle line as a whole, not any individual car. Only the manufacturer can confirm whether a specific vehicle is affected, and whether its recall work has already been carried out. Check yours by VIN and read the official notice at nhtsa.gov/recalls.

This page describes the recall, not any one car. To see which recalls cover a specific vehicle, search by make, model and year.
A VIN lookup here identifies your vehicle and shows recalls issued for that make, model and year. It cannot tell you what is still open on your individual car - only the manufacturer knows that. Search by VIN instead, or check your VIN at nhtsa.gov for whether a recall is still open on your individual car.
