1. Simple cost cutting measure by GM. They did it on the Silverado's in 2020.
2. You can buy the black tips from GM or have your chrome ones powder coated.
3. Agreed. I had a 2020 Silverado RST, a 2021 GMC AT4, and now the refresh 2022 Silverado LTZ. The GMC AT4 had less cab noise than the 2020 Silverado, but the 2022 LTZ has even less than the AT4. I think my reduction in noise may be due to the AT4 had the 20" mud tires and not the all-terrain tires. The 2022 does seem to have less noise than the 2020 though.
4. The Bose does sound good in the 2022, but I can't for the life of me find the speed adjusted volume setting. I do think the bass in the 2021 AT4 hit a little harder than the 2022.
5. All 3 of mine were the 3.0. The 2020 RST averaged 25 mpg in the city and 29-30 on the highway (it had the 18" wheels and 31" tires). The 2021 AT4 did the worse, obviously, but still got in the 20-25 range consistently. The 2022 LTZ has only been on 1 trip in the 2,8xx miles it has on it. It did very well averaging 27. The 2021 AT4 and the 2022 LTZ have both had the S&B intake and the PPE turbo resonator delete on them.
6. I feel the same way about the 2022 transmission. It does seem to hold gears longer and seems to shift a tad harder than the other 2 trucks.
7. My 2021 AT4 had Sport Mode (built in August 2021), but I saw that the later built AT4's didn't have Sport Mode.
8. The temp gauge on the dash is really just a dummy gauge. They haven't been accurate since the mid-90's.
9. The longer crank is the "fix" for the crank no start issues that plagued the 2021+ models. My 2022 LTZ does the same thing. That was the first thing I noticed when I drove the 2022.
10. Get the Autostop Eliminator (https://www.autostopeliminator.com/collections/gm/products/2019-silverado-sierra-autostop-eliminator). It is worth it. I don't like the Start/Stop on any vehicle.
11. The storage compartment in the center console is smaller than the pre-refresh trucks. The console itself is the same physical size.
12. This was on some of the 2022 models. It seems like it is hit or miss for when GM puts this in the trucks. You can also roll all the windows down by holding down the unlock button on the key fob, if you've turned it on in the settings, even if you don't have the button on the dash.
The only thing that some people have a problem with in the refresh interior is it does require the data plan to have the built in Google Maps operate. That doesn't bother me as I do pay for the data plan.
The only complaint I have with my 2022 LTZ refresh is the wheels. I like the polished LTZ wheels on the 2019-2022 LTD's. The wheels now look almost exactly like the Custom 20" wheels. I'm hoping to find a set of 2019-2021 LTZ wheels that are polished to swap out, as long as they are not that expensive.
