A large recall has been issued by GM (GM) for several models of its SUVs and pickup trucks. The recall affects as many as 638,068 vehicles and could cause unintended braking because of a software issue.

The recall was issued for GM’s 2015 to 2020 Chevrolet Suburban, Tahoe, and Yukon SUVs, and 2014 to 2018 Chevrolet Silverado 1500 and GMC Sierra 1500 pickup trucks that are equipped with a 5.3-liter engine, a 3.08-ratio rear axle, and four-wheel drive.

The issue with the vehicles stems from software problem that could unintendedly active the driveline protection system, which could cause the vehicle to brake without warning.

If one of the wheel speed sensors fail, the Electronic Brake Control Module (EBCM) software could activate the vehicle’s driveline protection system. This could cause the wheel on the opposite side of the failed sensor to brake, making the truck or SUV pull to one side unexpectedly, increasing the risk of a crash.

To repair the issue, GM dealers will reprogram the EBCM free of charge. GM has not published a notification schedule for owners to date.

Questions about the recall can be directed to Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782.

The recall number is N192261050.
