General Motors is recalling 285,622 model year 2021 Buick Envisions, Cadillac CT4s, CT5s, Escalades, Escalade ESVs, Chevrolet Tahoes, Corvettes, Suburbans, and GMC Yukons & Yukon XLs.

The communications gateway module incorrectly processes a loss of communication with the sensing diagnostic module (SDM), causing the airbag malfunction indicator light to illuminate inconsistently.

As a result, the airbag malfunction indicator light may fail to warn the driver of a problem with the airbag, increasing the risk of injury.

What to do

Dealers will update the software in the communications gateway module free of charge.

Owner notification letters are expected to be mailed July 19, 2021.

Owners may contact Buick customer service at (800) 521-7300, Cadillac customer service at (800) 458-8006, Chevrolet customer service at (800) 222-1020, or GMC customer service at 1(800) 462-8782. GM's number for this recall is N212338110.
