  1. Wheel cylinders (service brakes)

    NHTSA 85V048000 Reported 1,810,000 vehicles potentially affected GENERAL MOTORS CORP.

    Excessive enlargement of the wheel cylinder pilot hole in the rear brake backing plate could allow the wheel cylinder to rotate and cause loss of brake fluid. Consequence of defect: a loss of brake fluid leads to loss of rear brake action, creating the potential for an accident. Front brakes would remain operational.

    Remedy: Add a part to prevent wheel cylinder from rotating.

  2. Axle shaft (power train)

    NHTSA 84V149000 Reported 3,100,000 vehicles potentially affected GENERAL MOTORS CORP.

    Remedy: The dealer will inspect the rear axle to determine whether it was manufactured at the buffalo plant. If so, they will make axle measurements and if necessary replace or modify affected axle components without charge.

    Remedy: Both rear control arm attachment bolts will be replaced without charge.

This can result in inadequate lubrication of the bearing. This condition may be further aggravated by improper adjustment of the front wheel spindle nut.

    Remedy: The dealer will install new front wheel outer bearings packed with grease and the spindle will be coated with lubricant. New grease retainer caps will also be installed to maintain grease in outer bearing. This will be…

Checking a specific 1978 GMC Caballero

How do I know if my 1978 GMC Caballero has an open recall?

Enter your 17-character VIN above. The VIN is on the driver's side dashboard (visible through the windshield), the driver's door jamb sticker, and your registration or insurance card. The check runs against NHTSA's live database and tells you which campaigns list your vehicle. 4 campaigns currently list the 1978 GMC Caballero; your car may already have been repaired under some of them.

Is the recall repair free?

Yes. Under federal law, manufacturers must fix safety recalls at no charge for vehicles up to 15 years old from the date of sale to the first owner. Contact any authorised GMC dealer with your VIN and the NHTSA campaign number (for example 79V175000).

What is the difference between a recall and a complaint?

A recall is a safety campaign filed by the manufacturer or ordered by NHTSA, with a defined defect and remedy. A complaint is a report an owner sent to NHTSA; it is not verified, but patterns of complaints are what trigger NHTSA investigations and, eventually, recalls.
