Here’s Why Your 2022 Chevy Tahoe And Suburban Headlamps May Turn On In Daytime13
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.
Under the skin, both SUVs ride on the GM T1 platform, while production takes place at the GM Arlington plant located in Texas.

GM has offered automatic headlights for 58 years, and now has a “programming issue” affecting function. How’s that for progress?
This also happens on my ‘22 Colorado
The electronics are now made in China instead of the plant of design and production origin, Guide Lamp Div. in Anderson, Indiana
We had this issue with a GMC and the dealer couldn’t figure it out. Finally they replaced the sensor on the dash, everything worked fine….even though they didn’t believe that would work They wanted to take the entire dash apart to get to the bcm.
Vehicles have become so overly complicated, I remember way back when if you wanted your headlights on you just pulled on the knob and if you wanted them off you just pushed the knob in. If it didn’t work you replaced that $10 part. You didn’t need a computer to see what’s wrong with the car’s computer. I miss those days.
And a button on the floor to go from bright to dim. Every now and then, my left foot still looks for that button.
Is there a fix for the 2017 Silverado 1500 whose lights turn on at random times when passing through a shadow on the road? The sensor is too sensitive!
Wish I had not bought this truck, so many problems with it. Lost trust/faith in GM.
Four weeks tomorrow waiting for parts to fix my 9 month old TAHOE with 5200 miles and major lifter problems..THis is turning into a joke……Sitting at Chevy dealer since 9/7/22
That “joke” ain’t funny
9 Month old 2022 TAHOE with major lifter problems at 5200 miles. Sitting at dealers lot since Sept. 7, 2022
Had this issue from day 1 with my 22 Tahoe. Got a new OEM sensor from ebay $15 and replaced in few minutes and all is fine now. Wasn’t worth the hassle of dropping at dealer for $15 out of pocket. Seems like the sensor is the issue rather than the BCM.
DG, the dealer did replace our sensor, but that did not fix our issue. The software update finally worked for our ’22 Tahoe.
