Component
EXTERIOR LIGHTING:LIGHTING CONTROL MODULE:SOFTWARE
Manufacturer
General Motors, LLC
What Happened
The lighting control module is a computer that helps control your vehicle's exterior lights. In some 2020-2023 models of Cadillac, Buick, Chevrolet, and GMC vehicles, this module's software might not turn off the daytime running lights when your headlights are on.
Risk if Unfixed
If your DRLs don't turn off with your headlights, they could create a glare that reduces visibility at night, increasing the risk of a crash.
Free Fix
Your dealer will update the body control module's software either in-person or through an over-the-air update, and this repair is free.
