DESCRIPTION OF DEFECT

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
CONSEQUENCE OF DEFECT
DRLs that do not deactivate as intended may result in a glare, reducing visibility, and increasing the risk of a crash.
CORRECTIVE ACTION
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 are expected to be mailed January 23, 2023.
