Issue: On certain trucks, the repairs completed by a General Motors dealer during recall N192220470 (Transport Canada recall no. 2019-325) or customer satisfaction program no. N192270330 may not have been completed properly. As a result, a second repair is required. Additionally, certain trucks may not have had the updated parts installed during production. On certain trucks equipped with a power sliding rear window, the rear defroster wiring could overheat and melt. Safety Risk: Wiring that overheats and melts can create the risk of a fire. Corrective Actions: General Motors will notify owners by mail and advise you to take your truck to a dealership to replace the contact cover for the sliding rear window.

Issue: On certain vehicles, there may be an error in the electronic-brake control module software. This could cause the driveline-protection system to activate when a wheel-speed sensor fails. If this happens, the brakes could apply and cause the vehicle to pull to one side. Note: This recall only affects vehicles equipped with four-wheel drive, a 5.3-L engine, and a 3.08 ratio rear axle. The problem can only occur when the vehicle is in four-wheel drive or automatic mode, and travelling at a speed between 66 and 97 km/h (41 and 60 mph). A wheel-speed sensor failure will cause the electronic stability control (ESC) and anti-lock braking system (ABS) warning lights to turn on, and a "Service StabiliTrak" message to display. Safety Risk: A vehicle that suddenly pulls to one side could increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to update the electronic-brake control module software. General Motors advises that using two-wheel-drive mode can eliminate the risk until the recall repair is completed.
