On certain vehicles, a software problem could cause the airbag warning light not to turn on when there is a fault in the airbag system. As a result, a driver might not be alerted of the problem and the airbags may not work properly in a crash.
Safety Risk
An airbag system that does not work properly could create an increased risk of injury in a crash.
Corrective Actions
General Motors will notify owners by mail and send a wireless over-the-air software update to each vehicle. Alternatively, you may schedule an appointment to have the update performed by a dealer.
