SUMMARY:
Certain pickup trucks and sport utility vehicles may experience unwanted Antilock Brake System (ABS) activation. This condition is more likely to occur in environmentally corrosive areas. This recall will be launched in the "SALT BELT" states of Connecticut, Illinois, Indiana, Massachusetts, Maine, Michigan, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont and West Virginia only.

CONSEQUENCE:
This can cause increased stopping distances during low-speed brake applications, which could result in a crash.

REMEDY:
Dealers are to remove the wheel speed sensor and thoroughly clean the wheel speed sensor mounting surface on the bearing, apply rust inhibitor to the cleaned surface, grease the mounting surface, reinstall the wheel speed sensor, and check the peak-to-peak output voltage to ensure the wheel speed signal is within specifications. The manufacturer has not yet provided an owner notification schedule. Owners should contact Chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463.
