Hello,

 

I ordered a new 2026 LTZ back in October 2025. The truck arrived at the dealership in December. It was immediately sent to Harbor utility bed company where the factory bed was replaced. From here is when all hell breaks loose...the truck was returned back to the dealership with no working taillights. The dealer told me they will get it fixed. They have sent it to many different shops after their own services department couldn't figure out how to get the problem fixed...they said it needs a reflash then they said they need to change resistors on wiring harness...apparently it is completely different than a 2025. Long story short, they have had the truck for over two months and everyday I receive a message that they are still trying to get a solution and working with GM to fix the problem. Has anyone one else experience this and found a solution to this issue with 2026 LTZ trucks and utility bed conversions? Thank you!

No real solution and sorry to hear about this debacle!

 

I expect that the tail lights that came out of the truck were LED and that is why they are having a problem. If I was changing out the lights to fit a new rear deck, I would go aftermarket and maybe utilize one of the 7 pin connections if I ran into trouble with the tail light connectors and wiring.

 

I have a hitch light plugged into the 7 pin harness and it works for back up, running lights and brake. Even if you taped into the turn wires in the connector, you could power the turn signals as well. 

 

It shouldn't be too hard to make it work.

maybe see if gmupfitter.com has info released for your vehicle?  course, the dealer and utility bed company should both be aware of this site, for this kind of info...

      Tire pressure for 37s

      By PBNB · Posted

      Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter

      My First Project and GMC has me stumped

      By asilverblazer · Posted

      I had an alternator fail that was shorted internally in such a direct fashion in addition to the larger gauge cables that it appeared like a VERY dead battery. Granted I think the car did power up, it definitely wouldn't start.   Rodent damage to wiring?

      Using experience to justify bad advice is lazy and typical of someone incapable of articulating why their advice is prudent.    This immediately sets off the BS alert and the advice that followed certainly qualified.   Asking an idiot for help getting out of dumb situations because he is an expert... at getting himself into dumb situations.   Unless I've been living in an alternate universe - the first thing everyone does when getting into a sticky situation is shift to a higher gear 🤨.   Of course not, the torque multiplication, mechanical advantage and finer control typically afforded by the lower gear is far better suited for this scenario.   There ARE scenarios where a higher gear MIGHT be appropriate determined more by the drivers ability to control EXCESSIVE wheel spin versus applying torque to the ground.

      I'm not sure I agree with "extreme" low speed, high torque sentiment here with regards to the prescribed use of low range. How about...whenever it's needed?   A 2.72:1 transfer case and whatever differential gears these Silverados have (3.42's, maybe?) aren't producing "extremely" low crawl speeds. Or insanely high torque multiplication. Even with the 1st gear in these newer transmissions. But it does provide mechanical advantage and potentially better control at slower speeds. And with extra weight or towing, I think it adds mechanical sympathy for the truck as well.   Plus, traction control and the other assists generally turn off when you shift into low range. Those aren't needed here, they'll work against you if you need wheel spin. In high range you'll need to figure out how to turn off the various modes those assists provide. Depending on the vehicle, those things don't all automatically turn off or turn completely off.   While I agree that a farmer might have some great practical experience, a recommendation to "always" using one gear isn't very informed advice. If the farmer had said WHY and could explain the physics behind his prescriptive "always" I'd definitely listen. The way he's described here makes it sounds like he could either be uninformed or is telling everyone what worked for him, not necessarily that there could be a more advantageous way about things.
