Depends on what model and options you want, and your dealer's allocation. For example - I ordered a Suburban High Country with the Duramax and High Country Deluxe package on 12/9. It is still sitting in 1100 today. Diesels were on a 10% max production constraint through December (may have been extended - cannot find info on that). This week, GM put the Air Suspension and NHT Max Tow packages on constraint. Basically they are not building anything with those options at the moment and your order will sit. On top of that, in the case of my individual dealer - they did not get any Suburbans allocated for the month of January. Even though I have a sold order at the top of their stack, GM would not give them a Suburban last month. Supposedly whatever the first Suburban allocation they get for February will get assigned to my build. Now that they constrained it, who the hell knows.

Not that I am going to engage you on this again, but let's see a 4.3 do what you are stating above. It can't, no engine can. Now, review the video above to see it operating as designed... which if you were to run neck and neck with your beloved 4.3 you would see it get its ass handed to it... 12% more torque and a broader, flatter torque curve where it matters...

Aside from the harness issues early on, the engine itself has been flawless. The trans is awful, and the rest of the truck is a huge disappointment in terms of reliability and quality. My A/C compressor is making a racket at the moment and the steering alternates between honking like a goose and binding up and making loud banging noises under the dash that GM can’t figure out. I have 19k miles on mine since April, about 5k of which were put on while towing my boat. Average mpg for me has slipped a bit to 23.8, but I’ve spent a lot of time in the mountains lately.

You can probably thank me being ground zero and having to sue GM for this. Yay for being an early adopter. Get it in and get it fixed quickly, if that harness rubs through it will leave you for dead - either by not starting or it will leave you in the middle of the road With no warning.

You'll be fine towing. Pulling 5,000lb in the mountains at 70, I have never had mine touch 200. It does a nice job of thermal management.

The tailgate release on the non-powered gate is just a release - it does not power down. Mine almost never drops because the seal on my tonneau puts enough pressure to hold it up. You won't damage anything.

It was a bonus for me. I would almost never use 4LO (the torque of the 2.7T is perfectly fine for the steepest boat ramps I have used), and I use Auto pretty much every time it rains.

Mines been at like 14% front and 16% rear for 2 weeks now. Tonight, this happened. The boat is in storage for the year so I don’t need my shitheap that badly. I’m gonna leave it with the dealer tomorrow and take a loaner and let them figure it out along with a couple of rattles and a transmission that endlessly shudders like a vibrating bed in a cheap roadside motel with a slug stuck in the coin slot. Apologies for the sideways pics.

14,500 miles on mine. The engine has been flawless from a hardware perspective - just the wiring harness issues earlier that were hell to fix. The 8 speed is a rough shifting piece of garbage, IMO/IME, but at least it's reliable. My average fuel economy has dropped over the past 2,000 miles and I am at about 21.4 right now - about half of those have been spent towing the boat so I am not going to gripe.

Here’s mine, filthy and putting in some work on the worst day of the year for me (winterizing ?)

I have used it goofing off a few times, but nothing serious. It does seem like it is trying to control the truck better - but nonetheless it is not groundbreaking. When at the launch I just throw it in 4hi and let it walk up the ramp without issue.

I use 87 unless I am towing in temps over 90*, at which point I will give it 91. Something seems wrong, or you are really being heavy footed with it. I have a 4x4 Double Cab with 22" wheels and get ~22 average without effort (cruise set to 75-80 on freeway) consistently across tanks - and can get 26-27 with pulse gliding at 60-65 MPH. Your MPG is lower than what I get dragging around ~4,100lb of boat.

This is what I sued GM over due to their inability to fix properly. The TSB is a garbage repair by GM. The harnesses need replaced, not repaired.

I pull roughly 5k from elevations from sea level to 3300 ft regularly. It pretty much wont come out of 8th gear without standing on the pedal to force it to.

Because it doesn’t know how to read and is busy trying to dig up some other incorrect bullshit to clog up the forums with...
