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.

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

Strange, haven't heard of this.  Is it only the GMCs?  Or are silverados also impacted?

1badc5... not sure what the chances are, but I just posted this same topic on another thread yesterday... see link to my post below. I have the exact same problem. My truck only has 6k miles and the drivers side DRL turned purplish blue at top only. I took it to GM already, they acknowledged it. However, I didn’t have time to leave it. I’ll be taking it back in the next few weeks to have them look again. Good to know your dealer replaced them with no issue. This is frustrating for sure.

Seems like this slope is about to get slippery.  

 

I kinda hope someone gets to keep the old and is willing to tear it down or send to someone that will.  Would be interested to see what the cause is

I’ll ask, but I’m sure GM will say they have to send the defective unit back to GM corporate. They need to figure out what’s going on and quit building units that are failing. It’s gonna suck once we get out of warranty and we are stuck with purple DRLs... or spend $1200 per lamp to replace them. I think I’ve seen maybe one Silverado on the road with a purple DRL. I’ve seen a few Sierra’s with the issue. I guess it’s not super prevalent.

Seems like a UV issue since it's only on the top edge.  Curious, are these trucks parked outside?


 

Yes, mine is parked outside all day. Too damn big to fit in my garage 😆. Not sure about UV. Only my drivers side has turned purple. Seems like something with the actual LEDs are failing. I read some article a while back about how all LEDs emit a blue color... and they apply a phosphor to change the light to white. If that’s the case, seems that the phosphor is failing.

We are having the same problem with streetlights in Wichita, KS. They are turning purple/blue.  It sounds like the same cause, a problem with the internals in the LED light.

Noticed the Blue LED on the top of my 2021 drivers side headlamp today, Built 4/21, 1100 miles.

Sorry to hear, seems this is a very common issue. As an update: I just took mine in finally last week. The dealership looked at it and said they would order a new headlight unit. Something like $1500 for just drivers side. Hopefully it arrives this week and I can get it installed.

Same issue on our 2020 Denali drivers side headlamp only on the top area; super odd but yes it’s led failure.

My concern is that it’s likely that GM hasn’t remedied the issue in manufacturing and that we are going to keep having this problem even after the units are replaced and then once the truck is out of warranty, we are stuck. Or out of pocket a lot of money. Based on the newest trucks (built in 2021) still having this issue, I’m not very confident.

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 have a 21 Trailboss, and I have noticed this as well. I saw it in a reflection as I was parking, otherwise I probably wouldn't have seen it. 

 

However, it does appear the one blueish color light has returned to its original bright white as I type this.  Not sure how/why, but I'm going to keep an eye on it.

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
