On certain vehicles, the recall repairs completed by a General Motors dealer during recall N242454440 (Transport Canada recall no. 2024-637) may not have been done correctly. As a result, a second repair is required. Over time, the transmission control valve could wear and lose pressure. If this happens, the transmission could shift harshly and could cause the rear wheels to lock up. Note: This recall only affects vehicles equipped with a diesel engine.
Rear wheels that lock suddenly could cause a loss of control and increase the risk of a crash.
General Motors will notify owners by mail and advise you to take your vehicle to a dealership to update the transmission control module software to detect excess wear in advance of a wheel lock up. If detected, a service engine light would turn on, a message would display in the instrument panel and the vehicle would be limited to fifth gear.

On certain trucks, water could leak into the exterior tailgate switch. As a result, the tailgate could unlatch and open unexpectedly while parked. If this happens, cargo that is not secured could fall out of the truck bed and onto the road when the vehicle is moving. Note: This recall only affects trucks equipped with a power-locking tailgate.
Cargo that falls from the truck bed could create a road hazard for others and increase the risk of a crash.
General Motors will notify owners by mail and advise you to take your truck to a dealership to replace the exterior tailgate switch. To reduce the safety risk, General Motors recommends that you should inspect the tailgate to ensure it's closed and latched before driving.
This recall is a new notification for owners that purchased a soft or hard tri-fold tonneau cover from a General Motors dealer. On certain trucks, the bed-cover could come loose while driving and detach from the truck. This problem affects soft and hard tri-fold tonneau covers that were sold as an accessory by General Motors dealers. Note: This recall is related to Transport Canada recalls 2019-494 and 2020-165. If your truck was previously repaired under either of those recalls, it does not require further repair under the new recall.
A tonneau cover that separates from a moving vehicle could create a hazard for other drivers and nearby people.
General Motors will notify owners by mail and instruct you to take your truck to a dealer to perform the recall repairs, including adding a tether to prevent the tonneau cover from detaching. Note: Until the recall repairs are completed, you can prevent the chance of the tonneau cover detaching by removing it from your truck and storing it.
On certain trucks, the seat belt brackets for the front-row centre seat may not be properly attached to the seat frame. As a result, the seat belt could detach, and may not work as designed in a crash.
A seat belt that detaches in a crash could create an increased risk of injury.
General Motors will notify owners by mail and instruct you to take your truck to a dealer to inspect the front-row centre seat belt bracket attachments. The dealer will reassemble the brackets correctly, if necessary.
On certain vehicles, there may be a problem with the side curtain airbag inflators. As a result, the airbags may not inflate properly in a crash.
An airbag that does inflate properly could create an increased risk of injury in a crash.
General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to replace the side curtain airbags.
On certain trucks equipped with dual rear wheels and work truck trim level, the roof-mounted front clearance and identification lamps were not installed. Canadian regulations require these lamps on vehicles that are more than 2,032 mm (80“) wide.
A vehicle without clearance and identification lamps could be less visible to other road users, which could increase the risk of a crash.
General Motors will notify owners by mail and instruct you to take your truck to a dealer to install the missing clearance and identification lamps.
On certain 2500 and 3500 series trucks, over time, the hood latch could fail. If this happens, the hood may open suddenly while driving.
If the hood opens while driving, it could block the driver's view and increase the risk of a crash.
General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to replace the hood assembly.
On certain trucks, after a crash where a front seat belt pretensioner deploys, the carpet could catch fire.
A fire that occurs after a crash could create an increased risk of injury.
General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to modify the seat belt pretensioner bracket.
