2022 GMC Yukon XL

Issue: 
On certain vehicles, the connecting rods and/or crankshaft components may not have been manufactured properly. As a result, the engine could make abnormal noises and a warning light may turn on. If you continue to drive the vehicle with these symptoms, the engine could fail. 
Note: This recall only affects certain vehicles equipped with a 6.2 L V8 gas engine. 

Safety Risk: 
An engine failure could cause a sudden loss of power to the wheels and increase the risk of a crash. 

Corrective Actions: 
General Motors will notify owners by mail and advise you to take your vehicle to inspect and, if necessary, repair or replace the engine. For vehicles that pass the engine inspection, the dealer will replace the oil with a higher viscosity oil, install a new oil fill cap, replace the oil filter, and add an insert to the owner's manual.

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: 
On certain vehicles, a software problem could cause the lower beam headlamps not to turn on as it becomes dark outside if the multi-function switch is in the "OFF" or "PARKING LAMP" position. This could also cause the daytime running lamps (DRLs) to turn off when the vehicle is moving. As a result, the vehicles may not meet certain requirements of Canadian regulations. 

Safety Risk: 
Headlamps and/or DRLs that don't turn on could reduce visibility, make the vehicle less visible to others 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 body control module (BCM)software.

Issue: 
On certain vehicles, the automatic headlamps may not turn on soon enough as it becomes dark outside. Canadian regulations require automatic headlamps to turn on when the ambient light level drops below a certain point (1000 lux). 

Safety Risk: 
Headlamps that don't turn on as it becomes dark outside could reduce visibility and increase the risk of a crash. 

Corrective Actions: 
General Motors will notify owners by mail and send a wireless over-the-air software update to eligible vehicles to update the body control module (BCM) software. Alternatively, you may schedule an appointment to have the update performed at a GM dealership.

Issue: 
On certain vehicles, the daytime running lamps (DRLs) may stay on when the headlamps are on. Canadian regulations require the DRLs to turn off when the headlamps are on. 

Safety Risk: 
Daytime running lamps that stay on could cause glare for oncoming drivers and increase the risk of a crash. 

Corrective Action: 
General Motors will notify owners by mail and instruct you to take your vehicle to a dealership to update the body control module (BCM) software.
