The transmission in your vehicle is the part that helps your car shift gears smoothly. In some 2019-2022 models with a 10-speed transmission, it could get damaged internally.
Risk if Unfixed
If the transmission gets damaged, it could cause your wheels to lock up while driving, which increases the risk of a crash.
Free Fix
Your authorized dealer will install software to monitor and prevent transmission damage, free of charge. You should schedule the update as soon as possible after receiving the recall notice.

EXTERIOR LIGHTING:LIGHTING CONTROL MODULE:SOFTWARE
Manufacturer
General Motors, LLC
What Happened
The lighting control module, like the brain of your car's exterior lights, is a computer that helps control your daytime running lights. In some 2020-2023 Cadillac, Buick, Chevrolet, and GMC models, this module might not turn off the DRLs when you turn on your headlights.
Risk if Unfixed
If your DRLs stay on when your headlights are on, they could cause glare, reducing visibility and making it harder to see the road ahead. This could increase the risk of a crash.
Free Fix
Your dealer will update the software in your body control module for free, so you won't have to pay a thing. You should schedule this update as soon as you get the recall notice, or contact the manufacturer's customer service line for more information.
