General Motors, LLC "GM" is recalling certain 2021 Buick Envision, Cadillac CT4, CT5, Escalade, Escalade ESV, Chevrolet Tahoe, Corvette, Suburban, GMC Yukon, Yukon XL vehicles. The communications gateway module incorrectly processes a loss of communication with the sensing diagnostic module "SDM", causing the air bag malfunction indicator light to inconsistently illuminate.
The air bag malfunction indicator light may fail to warn the driver of a problem with the air bag, increasing the risk of injury.
The communications gateway module software will be updated by a dealer, or through an over-the-air "OTA" update, free of charge. Owner notification letters were mailed on July 1, 2021. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782.
