Its usually the fuse block bolts. Also check the obvious, battery connections, all fuses fully seated, ground lugs etc. but it’s usually these.

Thanks for the advice! Luckily I didn't need to use the electrical tape! Did the battery disconnect, let it sit for 20 and she started right up. It did show a few warning messages about 4x4 and getting service but they went away after a few minutes and did not reappear after restarting.

I am still gonna take it in for service, I wonder if it has anything to do with a recent update?

I have had this starting issue happens to me. ‘22 Black Diamond 2 door 4cyl.- 1300 miles Got to my farm gate, engine auto shut off…opened gate, got back in & the engine won’t start. Key fob is in the vehicle. Foot is on the brake, it is on park but engine won’t start and all the gauges/power accessories are on. This happened a couple times on my ‘21 black Diamond 4cyl 4 door ( yes I have 2) but it was fixable by pushing the off button I think. 11,000 miles on the 4 door now and have not had this issue in at leastn5,000 miles. It has been in for one oil change/service.

This is such bullshit. I’m letting then’22 ( She-Hulk ) sit right now and will go out to see if it has reset itself soon. If not, I’ll disconnect the battery and reset that way.

Update: I went back out to check it and all the power/lights had turned off on their own. It started up like normal. I will be running it with auto stop/start off for a few weeks, starting now

Mine randomly throws all codes & makes noises when I've sat in it (turned off) for a little while somewhere. When I start it, it makes all kinds of noises & goes thru brake system failure, hill assist failure & other things, telling me to schedule service. Every time it has somehow turned the emergency brake on. Today I parked it & was in the house for hours. Went to move it & got all the noises & it said my emergency brake failure or fault. I didn't even have it on. Of course I didn't have my phone with me so I couldn't snap a picture. The message was gone by the time I got my phone & went back.

My baby was sitting while I was gone over the weekend, went to start her up today and this happened. Dealer said try jumping it but with all the lights and accessories coming on I don’t think its a dead battery, tried anyways but the tow guy said I need to take it in. Less than 1200 miles.

**UPDATE - Now 10.25.21 After I did the battery disconnect she started right up, went back two hours later to leave and it didn't start, again throwing all the codes. Called the tow truck, when they showed up an hour later, it started right up. Dealer had it for three days, all they could do is re-seat all the electrical connections and told me it was ready on Friday. I couldn't get it until Sunday, started no problem and got no more than 200 feet down the road and bam, all systems in fault again. It is now Monday afternoon, they have had the car all day and haven't been able to get it to to fault again, what a mess! They are going to keep it for the week, drive it everyday to see if it happens again. Starting to think I might have a lemon on my hands.

Just have the same issue. After using it a little on a dirt road, it lost power and I got to a sidewalk and it stalled it flashed the check engine and went off. I tried starting it again it would just crank but no start.
