On certain pickup and utility trucks, some of these vehicles have an air bag sensing diagnostic module (SDM) which contains an anomaly that could result in the driver and passenger's air bag failing to deploy during certain frontal crashes.
Dealers will recalibrate the SDM on the affected vehicles. Owner notification began August 28, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Chevrolet at 1-800-222-1020 or GMC at 1-800-462-8782.
