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.

Wiring that overheats and melts can create the risk of a fire.

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. The dealer will also update the heating, ventilation, and air conditioning (HVAC) software, if necessary. If the rear window or sliding glass assembly are damaged, they will be replaced.

On certain vehicles, there could be a reduction in power brake assist due to a decrease in output from the vacuum pump. This could cause a hard brake pedal and create an increase in brake pedal effort that is required to stop the vehicle. Note: This is an expansion of Transport Canada Recall 2019-324.

A sudden increase in brake pedal force could lead to an increase in stopping distance. This could increase the risk of a crash.

The company will notify owners by mail and instruct you to take your vehicle to a dealer to reprogram the electronic brake control module.

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.

A vehicle that suddenly pulls to one side could increase the risk of a crash.

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.

This recall is for aftermarket replacement rear window glass produced by Vitro Automotriz. Certain rear window glass may not have been properly tempered.

Glass that breaks in to large pieces could create a risk of injury.

The company will notify consumers by mail and instruct them to inspect the designation code marked on the rear window glass.
