GM is recalling certain 2015-2020 GMC Yukon vehicles equipped with a 5.3L engine, a 3.08-ratio rear axle and four-wheel-drive. If a wheel speed sensor fails, while the vehicle is travelling between 41 mph and 60 mph in four-wheel or automatic mod, the EBCM (electronic brake control module) software may activate the driveline protection system.
