AIR BAGS:SRS MALFUNCTION WARNING LAMP/LIGHT
- The defect
- 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.
- What it can cause
- The air bag malfunction indicator light may fail to warn the driver of a problem with the air bag, increasing the risk of injury.
- What the dealer does
- 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. GM's number for this recall is N212338110.
- NHTSA's note
- Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner. This one is fixed by a software update rather than a workshop visit.
Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup .
How this campaign compares
At 285,622 vehicles this is a bigger campaign than 96% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published. The middle campaign on file covers 472. It covers one model year, 2021, and the defect was reported to NHTSA in 2021, at or before the oldest model year it covers — as current as a recall gets.
Chevrolet vehicles have been recalled over the air bags 65 times before this, most recently in April 2021 as 21V246000. That is not evidence the earlier repair failed.
This site holds the complaint record for all 10 model years the campaign names. Their owners have filed 1,350 complaints with NHTSA, 23 of them before this campaign was filed. 59 of those name the air bags, the system this recall is about — a count of complaints, not of this defect.
The vehicles on this campaign carry 19 other recalls published here, the newest being: 25V619000 (fuel system, diesel), 25V274000 (engine and engine cooling), 25V148000 (power train), 24V797000 (power train).
Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
