General Motors is recalling more than 600,000 four-wheel drive trucks and SUVs because a software error could activate the braking system, increasing the risk of a crash. The recall covers the 2014-2018 Chevrolet Silverado 1500, 2015-2020 Chevrolet Suburban, 2015-2020 Chevrolet Tahoe, 2014-2018 GMC Sierra 1500 and 2015-2020 GMC Yukon models. Officials say a GM authoritied dealership will reprogram the vehicles’ software free of charge.
