Exterior lights Vehicle recall #22V903000 · 2022 · 740,108 vehicles
What's wrong: The daytime running lights (drls) May not deactivate when the headlights are on. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "lamps, reflective devices, and associated equipment."
Why it matters: Drls that do not deactivate as intended May result in a glare, reducing visibility, and increasing the risk of a crash.
The fix: The body control module software will be updated by a dealer, or through an over-the-air (ota) update, free of charge. Owner notification letters were mailed January 23, 2023.
