GM has issued a global recall on 4 million vehicles. A defect in air bag software linked to at least one death has prompted the recall. The automaker says in rare cases, the car’s computers can go into test mode, which means the front air bags won’t inflate in a crash and the seat belts may not function.The recall covers a wide range of vehicles from the 2014 through 2017 model years and includes the following:

2014-2016 Buick LaCrosse, Chevrolet SS and Spark EV

2014-2017 Buick Encore, GMC Sierra and Chevrolet Corvette, Trax, Caprice and Silverado

2015-2017 Chevrolet Tahoe, Suburban and Silverado HD, GMC Yukon, Yukon XL and SIerra HD and Cadillac Escalade and Escalade ESV

Roughly 3.6 million of the recalled vehicles are in the United States. In 2014, GM recalled nearly 2.6 million vehicles because of an ignition-switch defect that prevented air bags from deploying in some crashes. GM’s independent fund set up to compensate victims awarded $594.5 million and approved 124 death and 275 injury claims in connection with that recall.
