2021 Cadillac XT4

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 advise you to take your vehicle to a dealership to update the body control module (BCM) software.

Issue: 
On certain vehicles, a bolt that attaches the rear seat belt retractor(s) may be missing. As a result, the seat belt may not work as designed in a crash. 
Note: On Chevrolet Malibu models, the right rear seat belt could be affected. On Cadillac XT4 models, both the left and right rear seat belts could be affected. 

Safety Risk: 
A seat belt that does not work properly could increase the risk of injury in a crash. 

Corrective Actions: 
General Motors will notify owners by mail and instruct you to take your vehicle to check that the rear seat belt retractor bolts are properly installed. The dealer will replace or tighten the bolt(s), as required.
