EXTERIOR LIGHTING Safety Recalls

Moderate #22V903000 Plain English
Component

EXTERIOR LIGHTING:LIGHTING CONTROL MODULE:SOFTWARE

Manufacturer
General Motors, LLC
What Happened
The lighting control module in your vehicle is a computer that helps control your headlights and daytime running lights. In certain 2020-2023 Cadillac, Buick, Chevrolet, and GMC models, this module may not turn off the DRLs when your headlights are on.
Risk if Unfixed
If your DRLs stay on when your headlights are on, they could cause a glare that reduces visibility at night, making it harder to see the road and increasing the risk of a crash.
Free Fix
Your dealer will update the software in your vehicle's lighting control module, either in-person or through a remote update, at no cost to you. You should schedule the update after checking repair availability with your dealer. This timing describes the original 2022 filing; contact your dealer now to confirm the free repair is available.
