These posts always crack me up, 3 people here have it, 3... A few people with the issue or a small handful all of a sudden it is labeled as common issue that almost every truck has when it is probably a 0.000X% of people that actually have had the issue. Lets not make it something it isn't, people did that with the AFM failures and valve coking to name a few; made it out to be some common issue when very few even on the forums had it where most people go just to complain.

I would disagree with you. I’ve noticed dozens of GMCs with this same issue in the smallish town I live in. I’m not making the claim due to 3 people on this forum and I’m not labeling it that every truck has this issue. Obviously it’s a somewhat small percentage of overall trucks on the road, but it’s still a prevalent issue.

Yep , a couple of our work truck sierras had them.  Made Appt and GM just replaced the headlights. ( both are 20 MY) while my 2019 Sierra does not have the BLUE .  Interesting now as i drive around town , I will see a couple here and there with the Blue. 

I would think its a simple issue but when your replacing headlight housings , there is something else going on.

I see this all the time, I just wonder if the owner even realizes the defect.


I think mostly only the OCD people, like the majority of us on these forums even notice or care. Haha

Does the new one match up color wise to the old light? Not to get you all paranoid or anything hahaha

After reading this I looked and my 2021 delivered in late March has the issue on  the drivers side light  too so its still out there.

Is the LED's bulbs going bad somehow ? Never seen them going from white to blue .

Maybe someone with Light/electric knowledge can chime in . ( Yes I know its not a big deal , but same time the OCD in me says get it fixed )

Wow... there is something deeper going on here... why is it that mostly it’s the drivers side going bad? And so quickly. Seems they are faulty/failing straight from factory.

I'm guessing large (YUUUGE) bad batch of these I'll try to get the date code off of this one, our truck was built in Oct '20 though so thats a hell of a gap if this is fresh-ish stock from GM.

There are a lot of post about the DRL turning blue on FB groups. I didn't see any post on the forum so thought I would start one so everyone could share if they are having same problem.

I have 2020 AT4 with 22K miles. Just had dealer replace both headlights because of them turning blue.

    • Follows the motif on the Sierra EV.  Satin finsh to the lower bumper area, painted above:   Elevation       Denali      
    • Not exactly what I was hoping for, but I do like it. I wonder if they'll bring back Smokey Quartz Metallic? 🤔 https://gmauthority.com/blog/2026/06/here-is-the-all-new-2027-gmc-sierra-1500/
    • Whoever greenlighted the work truck matte black front bumpers on every trim but the AT4X should be fired!  I was hoping that was an AI mistake, but just realized they were on every model of the 2027 Silverado too.     Some parts of the interior do look premium, but the Denali Ultimate dashboard looks like an afterthought.  At least they appear to have lost the microfiber the high end Silverado models showed, but the '27 High Country dash looks better than the Denali.  
    • New member here. I am researching a read-first event-recorder concept for late-model GM V8 trucks. This is not a sales post. There is no product link, price, preorder, or mailing list. I am trying to determine whether the underlying problem is real before building anything.   Has your truck ever had a brief problem such as: - rough running or a momentary misfire - an oil-pressure warning or unusual pressure event - reduced power or a brief stall - a U-code or lost-communication problem - a symptom that disappeared before the dealer or independent shop could reproduce it   If so, I would appreciate the following details: - year, model, engine, and mileage - what happened and under what conditions - whether a DTC and useful freeze-frame data were stored - whether the shop was able to reproduce it - what the eventual confirmed repair was, if known - what additional information would have helped the diagnosis   The concept being evaluated is a removable leave-in recorder that continuously retains a rolling window from before and after an event. It would not tune, reflash, clear codes, or change the vehicle calibration.   I am also not claiming that it could predict lifter failure or see every internal ECM variable.   The real question is whether continuous event history would add enough useful evidence beyond freeze frame, GDS2, and existing scan tools — or whether it would simply be another unnecessary gadget.   For owners and technicians, which problem would make something like this genuinely useful: 1. intermittent misfire or AFM/DFM-related behavior 2. oil-pressure events 3. lost communication or electrical faults 4. none of the above Please be blunt. Negative feedback is just as useful as positive feedback.
    • No tears over the SLE and SLT trim levels disappearing but I kind of loathe the "Elevation" name. It's a truck--skip the elegance.   The slab-dashboard design is decidedly different. Almost has a Hummer flavor to it. "Professional Grade" seems to be leaning very white-collar, tech-driven these days moreso than blue-collar, functional design.   The Silverado would be my choice between the two new trucks. Pleased with the engine lineup in both. The GMC is a little "too much" for a truck, IMO, and the Denali borders on ridiculous - but I do know there are buyers for luxury trucks out there. It's just not my speed.
