Summary: Vehicle description: certain 4-wheel drive pickup trucks and sport utility vehicles equipped with ABS (antilock braking system) manufactured from September 1989 through August 1996.

Consequence: If this occurred at a time when minimum stopping distance was required, a vehicle crash could occur without prior warning.
Remedy: Dealers will replace or repair the 4-wheel/2-wheel drive switch.

Has your Chevrolet been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Chevrolet dealer can also check your VIN. Recall repairs are free.
