GM Recall: Airbag Warning Lights Fail To Alert Drivers

General Motors is recalling more than 301,000 vehicles because the airbag warning lights inconsistently illuminate and fail to warn drivers of airbag failure.

Vehicles affected by the recall include 2021 Buick Envision, Cadillac CT4, Cadillac CT5, Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Chevrolet Corvette, Chevrolet Suburban, GMC Yukon and Yukon XL models.

The airbag warning light malfunctions because the communications gateway module, also known as the serial data gateway module, does not correctly store data that indicates loss of communication with the sensing diagnostic module.

As a result, the airbag light will only illuminate on every other ignition cycle.

General Motors issued the recall after finding 19 warranty claims potentially related to the airbag light problem.

Recall notices will be sent July 19. Dealers will update the communications gateway module software.

Some owners may have the updates performed at the dealership, while others may receive software updates wirelessly if they have accepted certain terms and conditions.
