Sportage 2023 PHEV inactivity battery shutdown

I am so glad to find this forum. 2023 Sportage PHEV. Drove it last night ~3 miles after I charged up the battery to about 30 miles, with about 30 miles of gas still in the tank. No problems last night. Got up this morning to take my son to school and it was completely dead. The door didn't respond to my fob, the charger didn't respond to plugging in (no "charging started" voice), nothing. Had to break in manually. Called kia assistance and getting a tow to the local dealership. Will provide an update. Hope I don't get the runaround today.
 
I have a 2023 Sportage PHEV and all electrical systems are currently down, buttons don't do anything, and there is no sign of life. It was only off for a few minutes before this happened. When I turned it on, it said key fob not detected. I cycled the power button and heard several systems make noise before everything went dead.

A portable battery jumper in the fuse box under the hood (positive on terminal, negative on chasis) did not work neither did attaching to the terminals on the 12v battery in the trunk.

Is this a similar issue to what others on this thread have experienced? Should I try jumping it from another car for more power?

UPDATE: I jumped from another car using the under-the-hood positive terminal and negative on structural metal. The car came back to life. So I'm confused how my car could have ended up with a dead battery in just a few minutes of the car being off. But glad it's back running.

I have a 2023 PHEV Sportage in last two months Four times and today I took it to Dealer in NY where I live and It happend in the parking lot which was good so they know there is an issue... It completley shutsdown no power but I have found a way to wake up the vehicle by opening the hood and shut close hard and it wakes up... so they are still investigating the issue... hopefully not serious... but this seems to happening too often and it should be considered recall for their PHEV vehicles. It is scary to go some where and not be able to get into the vehicle or even open the door.... so keep on reporting this to Kia please. and good luck to everyone.
 
Update to my last post where my battery was dead, KIA replaced the battery and here I am 6 months later with the exact same problem, battery only reads 4 volts. Boosted, revved the engine, restarted, then didn't start again. I need an aftermarket battery, KIA batteries no good
 
Update to my post, I monitored the battery voltage and it dropped sporadically, at times even going back up (on the second day) . The kia dealer noted that I had the kia hitch, and wiring harness installed and said the module could be the problem. Long story short, they disconnected the harness and I'm monitoring the battery for a few days, or a week to see what happens. My battery has died 5 times now, replaced twice.
