- Component
- AIR BAGS:FRONTAL; AIR BAGS:FRONTAL:SENSOR/CONTROL MODULE-INACTIVE; SEAT BELTS:PRETENSIONER
- Problem
- General Motors LLC (GM) is recalling certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles, 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles, 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles, and 2015-2017 GMC Sierra HD 2500 and 3500 vehicles. While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
- Risk
- A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
- Remedy
- GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017. 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 17287.
- Notes
- 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.safercar.gov.
What this recall means for you
Some vehicles may not have received the complete software update from an earlier air bag recall. Under certain driving conditions, the air bag sensing and diagnostic module can run a diagnostic test that stops the front air bags and seat belt pretensioners from deploying if a crash occurs.
If the front air bags or seat belt pretensioners fail to deploy in a crash that requires them, the risk of injury to the driver and front passenger increases.
The repair is free at an authorized dealer. The dealer will reflash the air bag sensing and diagnostic module software, and vehicles that have had a previous air bag deployment will have the module replaced. Owners will also be notified by the manufacturer. You can check your VIN for open recalls and contact your brand's customer service line for more information.
