I purchased a 2020 AT4 6.2L. Check engine light came on at 40 miles - went away after shutting it off and starting it. Fast forward 6 days - I have 350 miles on it and am NOT at home. Go to get into the truck after leaving 'fob' in the truck over night. The dash tells me "FOB Identified" or whatever the heck it says, and when I go to start my rig after it sitting for a day, I lose ALL power to the truck. Windows won't roll down, lights won't turn on - completely DEAD. I took the keyfob and stepped out of the rig trying to unlock/lock and even remote start and NOTHING. I asked a family member to give me a jump (thankful I was around other people - had I been in the woods I'd be screwed) after 3-4 minutes with cables on, the truck fires up and check engine light is on. After 15 minutes I shut the truck off and fired it right back up. Battery levels were fine - everything checked out except for the check engine light not going off. Drove it 140 miles home and it drove fine - until I took cruise control off and was heading home off the freeway, and it seemed to be "skipping/lunging" at low speeds, almost felt like a misfire/bad fuel or something. I called the dealership and took it in - they've had it for 1 week now and they claim the light came on due to a transmission code. I haven't heard BOO from them, but super frustrating that I spent as much as a did to have a truck that I don't have to drive now.....
