Had a similar issue have the dealer update the software if they tell you it’s already updated then they need to dump and reload it again. That’s what the dealer did to mine and it’s working fine. Good luck and let us know what happens.
I got my truck back, there not sure why the battery dumped but did find that the truck needed a complete software download. They think that may be why the battery drained. Charging and battery drain is normal now so we’ll see.
My truck is just a few weeks old only 500 miles on it. Went this evening to start it and everything is dead, jumped it and now every warning light is on. Looks like I’m going to the shop tomorrow morning! Will up date as soon as I get any info
