EXTERIOR LIGHTING:LIGHTING CONTROL MODULE:SOFTWARE
Manufacturer
General Motors, LLC
What Happened
The lighting control module is a computer that helps manage your exterior lights. In some 2020-2023 vehicles, this computer's software might not turn off your daytime running lights when you turn on your headlights.
Risk if Unfixed
If your DRLs stay on when your headlights are on, they could create a glare that reduces your visibility at night, making it harder to see the road and increasing the risk of a crash.
Free Fix
Your dealer will update the lighting control module's software, either in-person or remotely through an over-the-air update, completely free of charge. You should schedule this update as soon as you receive the recall notice.
