General Motors has issued a new recall spanning multiple brands and vehicles over a sensing and diagnostic software glitch that can prevent the vehicle’s airbag from deploying and allow the seat belt to malfunction.
The automaker stated that, in rare cases, the vehicle’s computer may run a diagnostic test. During the software’s test cycle, the air bags will not deploy and the seat belt pre-tensioners will not function in the event of an accident. GM stated the defect has been linked to one death.
The vehicles involved in this latest recall span the 2014 through 2017 model years and include the following:
- Buick Encore
- Buick LaCrosse (2014-2016)
- Cadillac Escalade and Escalade ESV
- Chevrolet Silverado 1500, 2500 HD and 3500 HD
- Chevrolet Tahoe
- Chevrolet Suburban
- C7 Corvette (2014-2017)
- Chevrolet Caprice Police Pursuit Vehicle
- Chevrolet SS
- Chevrolet Trax
- Chevrolet Spark EV
- GMC Sierra 1500, 2500 HD and 3500 HD
- GMC Yukon and Yukon XL.
As usual, GM will notify owners when a software update is ready for the vehicles to be performed free of charge at any local dealership. All vehicles will have the software updated and reflashed. If the airbags have previously been deployed, the SDM module will be replaced.
