Issue: 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. Safety Risk: Rear wheels that lock suddenly could cause a loss of control and increase the risk of a crash. Corrective Actions: 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.

Issue: 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. Safety Risk: A tonneau cover that separates from a moving vehicle could create a hazard for other drivers and nearby people. Corrective Actions: 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.
