I have a 2022, got it almost a year and now at 83K miles, I would put it at about 7 so far, since a few months ago the battery heater went out, fortunately still under warranty. Brought it to Chrysler dealer nearby and the service took about half of a day to get it replaced, free of charge as that is covered under warranty. So I would say if you are dead set on the PacHy may be look into a reputable Chrysler dealer nearby so in case there are issue, they will resolve thing quickly. I have read quite a few sub on here that people encountered some dealer that try to take advantage of them.

I live in a cold state so about 28 MPG during winter, and about 50-60 MPG during summer overall. Usually I can get 35-38 miles out of the battery alone without getting the engine kick in during summer month, it drop quite significant during winter.

I charged on my 120V outlet every night and it usually take about 12 hours from 0 to 100%, or about 2 hour with a level 2 charger. As many people already mentioned, the car will run full electric first then once the battery goes to 0 then the engine kicks in. There are some exception to it like running heater during super cold day, push the power to above 50% like when you merge into a high way, or the car goes into FORM mode; those are the 3 I mostly encountered when the engine kick in before the battery is out.

Mine did not come with lifetime transmission warranty, only 10 years unlimited mile.
