July 28, 2017—General Motors recalled 2014–2016 Buick LaCrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles; 2014–2017 Buick Encore, Chevrolet Corvette and Silverado 1500 and GMC Sierra 1500 vehicles; 2015–2016 Cadillac Escalade and Escalade ESV, Chevrolet Suburban and Silverado 2500 and 3500, Tahoe and Trax, and GMC Yukon and Yukon XL vehicles; and 2015–2017 GMC Sierra HD 2500 and 3500 vehicles.
The affected vehicles were involved in a previous recall but might not have received the complete software update that was necessary to remedy the recall condition. Without the complete update, certain driving conditions might cause the air-bag sensing-and-diagnostic module (SDM) software to activate a diagnostic test. As a result, the front air bags and seat-belt pretensioners wouldn’t deploy if a crash occurred during the test, which increases the risk of injury to the driver and front passenger.
General Motors will notify owners, and dealers will reflash the SDM software and will replace the SDM on vehicles in which the air bags previously deployed. These repairs will be done for free. The manufacturer hasn’t provided a notification schedule.
