The problem: GM has determined that certain units of the 2021 Chevy Tahoe and 2021 Chevy Suburban do not conform to the Federal / Canada Motor Vehicle Safety Standard (F/CMVSS) No. 108, “Lamps, reflective devices, and associated equipment.” Essentially, the DRLs remain on when the headlamps are turned on.
The hazards: if the DRLs do not deactivate when the primary headlamps are switched on, the resulting glare may increase the risk of a crash.
The fix: to address this issue, GM will update the onboard vehicle software in affected units’ Body Control Module (BCM). This fix may be performed through a dealer repair or through an over-the-air (OTA) programming update.
Affected components: vehicle DRLs.
