What is wrong

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).

Why it matters

Headlamps that don't turn on as it becomes dark outside could reduce visibility 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 seat belts may have been installed with the wrong bolts. As a result, the seat belt may not be properly attached and may not work as designed in a crash.

Why it matters

A seat belt that does not work properly could increase the 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 replace the seat belt bolts, as necessary.
