Looking at a ‘21 Denali

Like the title says, I’m looking hard at trading in my truck for a brand new Denali. I want one with pretty much every option, as this will be kept for a long long time. There’s a couple 6.2, and a couple 3.0.

I’ve read a lot of the posts, but I’m not sure what some common problems are with the ‘21s, as opposed to random problems here and there. I’m in Wisconsin, and I’m kinda looking towards the diesel. I don’t tow much, just a 16’ fishing boat or a 12’ utility trailer with a SxS on it.

 

Merry Christmas!!

Hey Mercracing - I have a '21 SLT premium plus. Overall love the truck. I have only had it for 11 days so far and already have the leaking rear sliding window. It appears they have not fixed this issue at the factory yet - so be aware and review the thread on that issue.  

 

 

Other than the above I love the truck and like it so much better than the 2018 F150 Platinum I traded. FYI I had numerous issues with the F150, included door latch recall (4 trips to dealer to fix it), ecoboost cam shaft phaser issue (required major engine work to solve), seat wire harness issues and the damn moon roof rattled from day 1 and they could never fix it. Truck had 30k miles on it and was ready to go out of warranty when I traded it. 

 

Good luck to you.

I have a '20 Denali......Carbon Black, 6.2 and loaded.  After five months and 5400 miles I'm very pleased with it.  No issues.  Tows a 6500 lb. travel trailer with ease.  I wish it had a larger fuel tank and had I been able to locate a 3.0 similarly equipped I would have gone with the diesel.  Have owned 2 German diesel SUV's in the past and loved their performance and fuel efficiency.

Happy hunting.

Go for the diesel; custom order it if you have too.  I have the 3.0L Duramax in my 2020 LTZ and it is really impressive with the 10 speed.  

 

Certainly, the 0-60 time is less than that of the 6.2L,  however I chose the diesel for longevity, durability, and MPG.

 

If you're just wanting to go fast and/or MPG is not a concern, then go for the 6.2L.

Sounds like the diesel should be the winner for me.
Does the 6.2 require premium fuel?

Recommended Premium Fuel for the 6.2

Don't think the longevity and durability is proven yet for the diesel

Plus the 6.2 so far in this form since 2014 has been solid. I'm on my 3rd , 2014 , 2016 and currently 2019 

A mix of 87 and 91 , never pinged and I drive em' like I stole em' 

I also have nothing bad to say against the Baby Dirty max, love that engine too

You're right, I should have stated "expected longevity and durability". Let's hope our expectations hold true.

3.0 has a 100,000 mile powertrain warranty, vs 60,000 powertrain for the gassers. 

 

(and since the change in the fall, it's also cheaper than the 6.2L)

100,000 miles, how many years?

Same as the gassers, 5 years. So if you aren’t gonna do more than 12k miles a year it makes no difference.

I'm looking at a new Denali also.  Is anyone getting much off besides the employee pricing and purchase allowance offers?

True, but the 100,000 miles speaks to the question of GM's degree of confidence in the reliability. 

 

Same warranty as the 6.6L Dmax

 

(fwiw, the 2.8L baby max does not get the 100,000 mile warranty)

 

Bumper to bumper is 3 year / 36,000 on all of them

      I'm looking at carpal tunnel surgery on my left hand and lumbar fusion.

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

      By Atlas · Posted

      While waiting for parts I have been working on installing the AC compressor, new accumulator, and orifice tube. Also changed out the high side ball valve (original). The orifice tube that was in there wasn't too bad. Slightly dirty, a little bit of junk, but not blocked. Glad I changed it out.   The accumulator, which should have been a 5 minute job, may have just burned $50. Put some PAG in it, wrote the date and mileage on the side, fresh o-rings and gooey'd up the threads and rings with Nylog. Got everything connected and snugged and was going to vacuum down the system, and....   My manifold gauge won't fit on the port. It's not an R12 service port. It LOOKS like an R134 service port but the diameter is a hair too large. There's a sticker on the accumulator that says it's designed to be used with R12 and R134a systems only. So it's not R1234yf. Even if I reduced the diameter slightly with a file, the shoulder on the port is too large so the quick-connect valve won't lock on. I'm stumped. It's going back, and 50/50 on if they'll give me a refund.   Also, I did a fuel pressure test.... Key on, the gauge spikes to about 60psi and quickly bleeds off, like 2psi per second. The fuel isn't going into the plenum, no smell, starts fine, so I'm guessing there's a bad check valve in the pump and the fuel is just draining back into the tank. oh, hell. But, it shouldn't be a problem, pump primes just fine and the truck starts right up. It just means I can't really ever use fuel pressure to verify a leak at the injector or intake.

      SERCICE ESC message?

      Got this yesterday out of nowhere. Truck is a 25',6.6 gasser with 8k miles.  Only semi anomaly is that the truck had been sitting, uncranked for 6 days. Elec Stability Control showed immediately upon cranking, not while driving. No drivability issues, just the message. Battery didn't seem to be weak when cranking over.  I drove it, killed it, let it sit a few hrs with no avail.  Truck is 100% stock. No damage.

      This can be done.  It is not cheap and requires an instrument cluster swap with custom programming, new steering wheel with the controls on it, and a special jumper harness.   The cluster upgrade - 12.3” Digital Cluster Upgrade – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The wheel upgrade - Steering Wheel Upgrade Kit – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The column harness upgrade - 2019 - 2026 Silverado / Sierra: Steering Wheel LIN Bus Harness - Harness Dr. - DIY Done Right     The problem with doing all of this?  You pretty much can't have any programming done to your truck that involves the cluster ever again.  The dealer won't be able to program the cluster as GM's system will only pull data for the cluster the truck came with.  So it would be advised also to turn off over the air updates.   TLDR;  Should have bought an LT double cab?  You'd have a power seat, the wheel controls, the cluster, all things that you've been seeking in your various posts so far about your new WT regular cab.
