This happened to me recently as well on my 2021 PacHy - extremely frustrating as I stalled on the highway 4 times on a trip from Milwaukee to Chicago and back again! Grateful that, each time, I was able to maneuver over to the right shoulder (without power!) and restart it after a minute or so.
I filed an NHTSA report (11494849 ). Chrysler needs to do something. Dealers cannot fix this issue. IMHO this needs to be a safety recall.
There is indeed a recall that was issued either today or yesterday. Seems like a software update but the issue is faulty wiring... you be the judge on how a software fix addresses physically faulty wiring.
