Trying to determine if a 2023 Sierra 1500 Denali Ultimate with super cruise control can be lifted.   would lift it 3.5" to 4"max.  Does anyone know if a lift will interfere with the super cruise control functionality?

Highly likely.  Super Cruise is designed to operate on a stock height truck and stock diameter tires, and then should account for something like trailer sag.  There are no reprogramming or calibrations to the system to tell the truck it has been raised because there is no factory lift kit that fits the Denali. 

 

Plus, Denali have the Adaptive Ride Control.  

 

Not an ideal truck to lift.

Unless you're making it a show truck (ie. 12" lift  and 40s and another 10 grand minimum) you're looking for headaches.

Good Morning,
 
As discussed on the phone, the vehicle cannot be lifted or leveled. The calibrations for the Super cruise system require the vehicle to be at as-built ride-height or the system may not function. If you have any questions or concerns, please reach out to me directly.
 
Sincerely,

That's what I thought. Too many things change when lifted .

Hi, found this forum searching for the same answer. Went ahead and went forward with a 6” on a 24 Denali ultimate 1500 and super cruise works just fine after.

Looks good! So no issues with SC? 
 

What kit did you use? 

No issues so far got 9000 miles on it now. I used the rough country 3.5 kit for the denali.

      How many miles were on the truck when you bought it and was there some form of oil change history generated through a dealer or an independent shop although not much would show up if the owner had changed their own oil. Just curious if it was a maintenance issue or if there was something off from the start, surely one would think the original owner would have realized it was using a lot of oil, its hard to go back in time and find out the true story of mysteries like this. Well hopefully the warranty company will go for it and just install a new engine, that would be the ideal outcome.    I still have so few miles on my truck as per not quite 9000 and will be changing the oil shortly which has around 2700 miles on it or so and its down so little on the dipstick from where it was at the beginning of this oil change that I could make the "claim" that it uses no oil but in reality would be a very small amount, less than a 1/16 of an inch. Just driving empty/not towing and easy driving so hard to say what it would do if it had a load behind it for oil consumption. So far very impressed with the very minimal oil usage.

      Doors lock and mirrors fold in while driving

      By BIGBOYS · Posted

      I have a 2015 Silverado and sometimes I can not get in to the truck. I use the key to unlock the driver door. Something is locking the truck when I unlock it, last night I left the truck open and this morning it was locked with the mirrors folded in. This happens while driving so it is now a safety issue. I reach down for the folding button and they open, then they close again.  Any advice, thank you,   Ed

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      tl; dr I've now reached the 6th floor of hell. I'm chronicling my journey for my morning readers.   Pulling the top of the intake apart was moderately easy but it involved a lot of parts, connections, and minutae. I was preparing for the new fuel lines to arrive ("nut and bolt kit" it's called). The fuel line connections are notched and held in place by the manifold and a metal plate with a T27 screw.   It's on the back of the intake, under the firewall, with little clearance, and two hard metal fuel lines in the way. I was using Franken-tools (weird combinations of 1/4 inch ratchet with/without an extension, with a bit holder for my T27) to get in there. One of my sockets and bits fell off and has yet to emerge on the floor. I lost a second setup and that's when I almost started throwing tools. But that was the point at which I had gotten traction on the Torx head, and it promptly stripped. No more traction.   I started humming "1-877-kars-4-kids" because I was about at that point. You know what? I'm $1500 into this thing and I can make it disappear just as quickly. This isn't fun anymore. I had spent a lot of time already "tidying" around the engine bay: Fixing all the "someone's been here before!" BS. The truck has been exclusively dealer- and shop- serviced and I'm reminded of why I never let other people work on my cars unless absolutely necessary.   Speaking of dealer service. This truck has a 1" stack of records going back to 1995. I put them all in an excel spreadsheet, date/mileage/description.   The CPI spider has been replaced 4 times in 85k miles. The EGR? Another 4. Multiple, multiple O2 sensors. One Cat. 4? Sets of plugs and wires, and I swear half the stack is diagnosis paperwork for "misfire, runs rough, extended crank, dies at stoplights".   GM was producing some proper crap back then. And it was still well within the era of brittle/crappy plastic. (Windows 95 was released the same month this truck was sold new, we HAD the technology!!)   There (was) a plastic shroud around the evaporator core and HVAC fan in the engine bay. I noticed a chunk of it missing so I poked at it some more and it literally shattered. Touched it some more and pieces were crumbling off. Had a good laugh. Clearly whatever plastic garbage they were using had broken down over 30 years and was literally turning to dust. That was a good half hour of using a shop vac to remove the rest of it.   Back to it.   I was going to give up for the evening but then decided I'm already level 10 pissed off at the stripped screw: G* D* it, give me my tools back -- and my JOY. We'll do this the hard way: The whole intake is coming off.   Blazer won Round II. After finally finding and accessing the 12 intake bolts and using a pry bar to unseat it from the heads, it popped loose in an explosion of gunk and grime raining down into open ports. Awesome.   6 times I reminded myself: Be careful of the temperature sender on the front of the intake.   YEAH, I forgot again and snapped it clean off in the removal. Add another $20 to the ever-growing list of new parts this thing is consuming.   The shame is, long before removing the intake, I had changed the oil in prep for Tuesday's momentous fuel line replacement that was going to be the magic fix and I'd have a running Blazer to tool around in this next weekend. The intake removal, including raining gunk, also gushed dirty coolant all over the valley. Of course it did. Welp, there goes another $35.   I now need an intake gasket set, bolt set, coolant temp sensor, another 5 quarts of oil, some RTV. Don't worry, I've already got 3 new jugs of Dexcool and a thermostat waiting. I'll fill it with clean water first to get it running, dump it, and then add the Dex later on in case... well, let's not go there. I'm only tearing this down once, next time the truck is going on Marketplace for FREE.   Oh, and I'm going to need vacuum hose for all the stupid connections placed at the rear of the engine which have since disintegrated. Come on, GM....tell me you don't do that anymore?   Oh, and the ears on the distributor where the cap screws down are both cracked. I mean, why not put a new distributor in it too. You get a distributor, YOU get a distributor, Everyone gets a new distributor!   This truck isn't out of the woods yet...I'm already questioning how much more time I'm willing to sink in.
