I’m pretty sure you can adjust it yourself... that’s what I had to do on my Colorado.

Hi my $56,000 2019 rst 5.3 8 speed 8-19 build date is just like you say my drivers side is higher, the issue here is the cab needs to be lifted there is only a left right forward back adjustment on the bed, my buddy's 2020 Sierra is also the same way,  I also thought my truck was dropped off the train or someone launched it but it's just very poor quality control at gm, i don't want to make you sad about your truck but I am so disappointed in my truck, my transmission is Awful, my rear window leaks water, and apparently this is all normal and can't be fixed, gm really does not care they would do anything to save 27cents,  one positive note is I've managed to go 5400 miles without having it towed....

This sounds like my issue. I wonder if there could be a washer or bushing missing on that left rear cab mount causing it to sit lower..? Or why the heck.? For a $54,300 truck, I just expect too much I guess

You could try this, gm only pays 24 minutes to fix so a $20.00 an hour tech gets like $9 subtract taxes = like $6 to fix so you should probably do it yourself if you want it right.

Correct me if I’m wrong, but this will not raise or lower the bed.. unless one of those plastic pins could be possibly pinched causing the bed to not sit down flat on the frame.?

On your transmission issue.. mine did shutter and almost felt as if slipping at times up until about 6,000 miles. Now currently it has been working perfectly.. not sure what happened but the shutter is gone. (I have been driving her hard to either make it finish itself off or fix itself.. idk if it helped or not!) LOL

Hi so it doesn't appear to lift or lower the bed,  in my case I need to Lift the body on left rear, I was going to get a cab mount bolt washer and  shim between mount and body, my bed is off to the right not sure if sliding it to the left will lower it doesn't appear to, I was going to adjust the bed after I lifted the body just haven't done that yet, I agree the price point of these vehicles. Bring it in line with high quality German luxury cars with high level of engineering  and manufacturing.

Have a simillar issue measured the bumper to ground on each side and its the same. Put a level on the bumper and its level. Problem appears to be the bed. So that means it could be adjusted as platform is level. You can see it when looking at bumper in relation to tail gate at the bottom. Its 3/4in off. Will have dealer take a look no accidents reported. 2021 2yr old

Update it appears the gas tank is on the left side of the truck. It is now full so 21g x 8.4lb=176lb maybe this is part of the issue.

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Missing thrust bearing? And oil selection

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
