What is wrong

Over time, the transmission control valve could wear and lose pressure. If this happens, the transmission could shift harshly and could cause the wheels to lock up. Note: This recall only affects vehicles equipped with a 10-speed automatic transmission.

Why it matters

Wheels that lock suddenly could cause a loss of control and increase the risk of a crash.

What the dealer will do

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.

What is wrong

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.

Why it matters

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.

What the dealer will do

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.

What is wrong

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.

Why it matters

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

What the dealer will do

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.

What is wrong

Why it matters

A roof-rail airbag that does not inflate properly could create an increased risk of injury in a crash.

What the dealer will do

General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to inspect the roof-rail airbags. If necessary, they will be reinstalled correctly.

What is wrong

Why it matters

An airbag system that does not work properly could create an increased risk of injury in a crash.

What the dealer will do

General Motors will notify owners by mail and send a wireless over-the-air software update to each vehicle. Alternatively, you may schedule an appointment to have the update performed by a dealer.
