Recall 17V437000

Air Bags and Seat Belts Do Not Deploy In An Accident

Recall Details

For vehicles repaired during a previous recall, the software for the air bag sensing and diagnostic module (SDM) may not have been updated. This could cause a diagnostic test to run while driving the vehicle, during which air bag and seat belt tensioner deployment will not occur. Dealers will reflash the SDM software free of charge to resolve the concern.

Our Quick Take

The software for the air bag sensing and diagnostic module may need to be updated, as the existing software may prevent deployment of air bags and seat belt pretensioners in an accident. This increases risk of occupant injury.

What Should You Do?

Recall repairs on your General Motors vehicle must be performed by a General Motors dealership. General Motors will notify known owners of affected vehicles (a timetable of this notification is unavailable as of the time of this writing). If you do not receive a notification, but wish to check to see if your vehicle is included, please contact one of your local General Motors dealerships. They will also check for any other incomplete recalls on your vehicle. For best results, be prepared to provide your Vehicle Identification Number (VIN) to the service department consultant you speak with. The General Motors recall number is 17287.

Summary
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.
Consequence
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 manufacturer has not yet provided a notification schedule. 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.
Notify
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.
