General Motors Co. (NYSE: GM) is recalling 3.64 million cars and light trucks sold in the U.S. and about 700,000 more sold worldwide to fix a software bug that prevents the front airbags from deploying in the event of a crash. The repair involves installing new software for the airbag sensing and diagnostic module (SDM).
The National Highway Traffic Safety Administration (NHTSA) is requiring GM to notify owners of the affected vehicles to take the vehicle to the dealer to reflash the SDM software. If the vehicle has had a previous airbag deployment the SDM will have to be replaced. Dealers may not charge customers anything for this service.

- Buick Encore: 2014-2017
