Just can't figure it out!  My new 2021 Sierra SLT has 1500 miles on it now, and despite everything I read around here, I can't find a thing wrong with it!  Every function and feature works as it should.  Must be some sort of strange anomaly!

God for you and I hope your good luck continues. 

 

I've had my 21 SLT since December 4th. So far windshield has been replaced, rear window leak, lifters replaced and the battery has been replaced. All under warranty, but doesn't bode well for durability and dependability. I do love the truck but hate having so many issues. Good luck to you with yours and I truly hope you don't have any issues. .

I'm assuming it has the 10 speed transmission?  If so, wait until 1900 miles, then the third gear shift solenoid in the valve body will grenade.... ask me how I know..... Other than that fiasco, truck has been solid.  24mpg on a trip to New Hampshire unloaded.

Amusing thread. Praising a 40-60K vehicle from a company that’s been around forever. For no problems under 10K miles. I use to get nervous after 100K. After much experience mid 90s to mid 2000s Large GMs I feel comfortable up to 200K. Now it’s back down to the end of the warranty period if I bought one. Only if I have a spare. That includes Ford and Ram.

Nope..it's an 8 speed w/5.3 and no DFM (chip shortage truck)

Just ticked past the 7,500 mark the other day, and the truck is being a very good boy with no issues since day 1.

Its there you just don't have the ability to use it. The lifters can still fail.

True, but I am not going to dwell on it and keep a positive outlook.

My '20 AT4 was perfect for the first 12mos and 14k miles...now dealing with tranny (10spd) related issues as well as brake related issues that keep triggering the engine light along with two other unknown engine light moments (according to dealer issue was not stored in computer).    Multiple software updates, new torque converter and the tranny still isn't right.

    • I had a similar but different response when I talked to the service manager where I bought my truck in that he said GM corporate won't allow them to lower the placard pressure setting as they would get their hand slapped but that of course they have the ability to make that change. His suggestion was simply go to a tire dealer or third party shop that is willing to reset the pressures lower. However I chose to buy a tpms tool and partly based off of this very forum as it had been proven to work on the 2024 model ( Global B system ) and while I could have paid lots for a full two way diag tool, I didn't want to spend that much and bought the recommended Autel TS 508 and it will reprogram the 2025 model and assume it should do the 2026 as well. However the tool is rather proprietary to reprogramming Autel tpms sensors so that is a function I will never use, where as a real two way scanner would have many uses but also have yearly subscriptions etc where this 508 is free updates for as long as they put updates out for the unit. In any event it worked to lower the placard pressures and I often use it to adjust my actual tire pressures although will check with a mechanical gauge as well sometimes just to make sure that tires tpms sensor isn't lying to me.    My suggestion is either buy a tool that you know will work to adjust the system or start out by getting the tire shop you bought your tires from to reset your truck and if after that you still want a unit to do it yourself, get one at that point. 
    • Here is an image of a quick Google search about these tires on my truck and it's exactly same psi recommendation the Toyo tires company gave me!    I'm not looking for anyone else recommended psi or anything, I'm just looking to see if anyone knew a way to get rid of the factory low psi warning light, because I'm not running high psi and ruining my tires when I'm not towing! 
    • 60psi front and 80psi rear But I am not running the factory tire brand or size! it's load range F Toyo tires
    • Open the driver's door jamb.  What do the cold tire PSI ratings on the tire placard show?   I'm not saying to run it to those numbers, but I would like to know what it says.
