Issue:
On certain vehicles, a software problem could cause the low brake fluid warning lamp not to turn on if the brake fluid level gets too low. A low brake fluid level can cause reduced braking.
Safety Risk:
A driver that isn't aware of a low brake fluid level could experience reduced braking and an increased 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 electronic brake control module software. Alternatively, you may schedule an appointment to have the update performed at a GM dealership.
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.
