2026 GMC Sierra – Price in Canada, Specs & Trims

Issue

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. This is an expansion of recall N232426400 (Transport Canada recall no. 2024-061).

Safety Risk

Cargo that falls from the truck bed could create a road hazard for others and increase the risk of a crash.

Corrective Actions

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.

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

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.
