Cadillac LYRIQ

Issue: 
On certain vehicles, a software problem could cause the driver video display (instrument cluster) to go blank while driving. If this happens, you may not be able to see certain information about the vehicle, including the speedometer, warnings, and tell-tales. In addition, the rearview camera image may not display when the transmission is shifted into reverse. 

Safety Risk: 
Warnings, tell-tales and gauges that don't display could increase the risk of a crash. Additionally, a rearview camera image that doesn't display could reduce a driver's ability to see behind the vehicle while backing up. This could also 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 video display control module software. Alternatively, you may schedule an appointment to have the update performed at a GM dealership.

Issue: 
On certain vehicles, the owner's manual may include the wrong instructions for how to adjust the left and right-rear head restraints. Canadian regulations require this information be included in the owner's manual. 

Safety Risk: 
Incorrect instructions for how to adjust head restraints could increase the risk of injury in a crash. 

Corrective Actions: 
General Motors will notify owners by mail and provide you with an owner's manual insert with the correct instructions for how to adjust the left and right-rear head restraints.

Issue: 
Under certain conditions, a software problem could cause the antilock braking system (ABS) not to work properly. As a result, the ABS could cause reduced braking or a loss of brakes. 
 
Safety Risk: 
Reduced braking or a loss of brakes can 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 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.
