Had pretty much mostly Mopars in the past. My last truck was a 2018 Ram 1500. Hemi, CC, 6.4 bed, Zone 6" lift, fox 2.5 shocks, grill guard, 36x13 R20 tires. Beautiful truck. Paid it off in June of 26, neighbor kid who's been driving for a month totaled it July 26 while it was parked outside of the house. Ugh.
We figured we'd change it up a bit and found a 2020 GMC 1500 Denali with 50,000 miles for a good price. Pick it up today or tomorrow.
I'm looking forward to learning about this truck. I've already started to youtube how to's on diff oil changes, t-case etc. (Not too thrilled that there's no drain plug on the diff's. The front looks like a bit of a PIA, but we'll see) I do most of my own routine maintenance and plan on changing out the fluids when I get it.
Anyway I'll post some pics when I bring it home.

This is NOT impact damage nor neglect. There were previous class action lawsuits because of such paint preparation st GM manufacturing plant. Not just the Cherry Red Color. This paint is applied in three processes to obtain the desired color. The manufacturer will cover for 36 months or 36k miles only. That rust is actually corrosion because of the paint process failure. Corrosion is covered for 100,100 miles or a certain months. However their corrosion doesn't include this type. Go figure.
Clearly manufacturer knew from previous paint issues.
This started 3 weeks ago out of the blue.
consider doing electrical testing? I would guess some power or ground wire/connection has a problem.
alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.
can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?
