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.
This bulletin applies to 2018-2019 Buick Enclave vehicles. The Service Parking Brake message may be seen, the red Park indicator may be flashing and/or the amber parking brake wrench indicator may be illuminated. Codes C056D or C056E may be stored, and other ABS codes may be found.
In rare cases, some owners of 2014 Cadillac Escalade vehicles equipped with a 6.2L engine may comment about the Service StabiliTrak message being displayed in the DIC. The StabiliTrak light may also be on.
This bulletin applies to 2007-2012 GMC Acadia vehicles. A “Service Stability” message may appear on the driver’s information center as a result of DTC C0561 set in the electronic brake control module (EBCM). The EBCM receives messages from the other modules over GMLAN which are needed to perform ABS, VSES and/or TCS functions.
