For those 2022 Chevy Tahoe and 2022 Chevy Suburban owners who notice their SUV’s headlamps automatically turning on during daylight conditions (rather than the Daytime Running Lamps), a cause and fix have been identified.
At present, some units of the 2022 Chevy Tahoe and 2022 Chevy Suburban may automatically turn on the primary headlamps during daylight conditions, as opposed to the Daytime Running Lamps, when the headlamp switch is set to the Auto position. The root of the issue is down to programming in the Body Control Module (BCM), which monitors the ambient light sensor signal circuit to determine if the lighting conditions require that either the Daytime Running Lamps be turned on, or the primary headlamps.
According to GM TechLink, Customers who experience this issue can fix it with updated BCM software. The software may be available via an over-the-air (OTA) programming event. As such, it’s recommended that customers monitor their vehicle infotainment system for any related software updates.
The 2022 Chevy Tahoe and 2022 Chevy Suburban are the second model years for each respective nameplate’s current generation, with the Tahoe now in its fifth generation, and the Suburban now in its twelfth generation. Both SUVs offer a trio of powerplant options, including the naturally aspirated 5.3L V8 L84 gasoline engine, rated at 355 horsepower at 5,600 rpm and 383 pound-feet of torque at 4,100 rpm, the naturally aspirated 6.2L V8 L87 gasoline engine, rated at 420 horsepower at 5,600 rpm and 460 pound-feet of torque at 4,100 rpm, and finally, the 3.0L I6 LM2 turbodiesel Duramax, rated at 277 horsepower at 3,750 rpm and 460 pound-feet of torque at 1,500 rpm.
