Just picked my AT4 last Monday the 22nd of July. Truck was ordered in early June. Mine is doing the same thing. Lights flicker every five minutes or so.

Got the new headlights installed, picked up the truck today. Went for a drive at nightfall, and bam, same thing. Total waste of time. Call dealer again tomorrow. Any there options as a buyer to maybe get out of this truck. If theres no fix yet from GM and we cant drive at night what are the owners of these vehicles suppose to do, this just boggles me.

Should have got online before we purchase our 2024 Canyon AT4!! Day one or should say night one, the headlight flicker syndrome is just what we were hoping to get with a new GM product!!!🙄 Bought  it with 5 miles on it and with the fact that there is a Service Bulletin (24NA005) out on this issue and they are still allowing people to buy these truck and leave the lot with them is baffling to me!!?? People keep tapping their brakes at me because they think I am flashing them or on coming traffic thinks I am flashing them so they bright light me. This is a major safety concern with all the possible complication that comes from this flawed work done by GM!!!

WRONG BULLETIN #.  That applies to 2024 HD trucks ONLY.

 

There is a PI for the Canyon headlight concern.  Its a parts supply/manufacturing issue.  All existing stock is not good either.

Bad stock on lights too.

Glad I saw this post, among others on the net. My wife and I were about ready to trade her 2021 zr2 Colorado on a 24 Canyon AT4.

Think we are going to hold off until 2025's. one thing i hate doing with a new vehicle is becoming friends on a first name basis with a service person.

 

We will be going to get our deposit back!

GM has a fix for it for 2024s.  They are replacing the LED Driver modules.

I went with another Colorado ZR2. Decided to stay Chevy, just not a GMC guy! Not as many options but I just love the look and the stance!

 

Pick it up next week!

 

Thanks for your input.

Same issue, recall is showing it was performed, but it still does it.   Dealer says they can't "replicate" the problem and refuses to fix it

Sorry, can't answer your question, but have you checked with Harry Dunne so see what he thinks😁

    • Late reply, but yes—it works on the SLT trim. Compatibility comes down to the plastic shroud shape behind your mirror, not the trim badge itself. On the SLT with auto-dimming, it uses a plug-and-play Y-harness off the mirror/rain sensor power, so no need to run wires down to the OBD port. If anyone's ever unsure about fitment, just drop a photo of your mirror housing and we can double-check it.   Appreciate the detailed feedback on the install! On the windshield glare—we actually took feedback like yours and developed a dedicated CPL (polarizer) filter to cut down dash reflections on sunny days. If you're still running the cam, shoot me a DM. I'd be happy to send a CPL filter over for you to test out—no charge. 
    • There are no stickers in your glovebox?
    • Look at the numbers on the stickers in the door jam...
    • Yes, every time the developer updates his code, you must recompile. I will private message you with the latest because it changes pretty much with every version.
    • After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.
