I had a similar experience this weekend. Was able to jump start but Jeep would die almost immediately after removing the jumper cables. After a couple of hours with AAA battery service, they had me do the following which allowed me to drive it to the nearest dealership. Also, the Engine Check/MIL light and Service Stop/Start System Warning lights were on.
  • Jump-start with jump box and leave it connected
  • Rev engine to 1500 RPM for 2-3 minutes.
  • During this time the Jeep "reset idle" according to the tech
  • Disconnect jump box and the Jeep stayed running
  • Disable Stop/Start system
  • Cross fingers and drive it on the road to nearest dealership
Jeep is in for service now but I'm still waiting on official diagnostic from them. More to come.

*My Jeep was not 2-days old but is a 2020 (not even 12-months old)
UPDATE-Dealer ran diagnostics and ended up replacing both batteries. So far so good but waiting for more time to pass before calling it 'fixed'.
