I'd say as a consumer you shouldn't be able to do anything that wrong! Did you keep the Jeep and the Tacoma?What am I doing with my Jeep? I brought back to dealership and immediately bought back the 2015 tacoma I had traded in. I am so happy to climb into my old car, now Jeep can keep 4xe and not disrupt my life, I don't want a stinky loaner.
Hybrid and electric are nearly the same thing when you have battery reserve. Hybrid will deplete the batter reserve first, just like electric. So that should be okay. It's normal for all PHEVs, not just the 4xe. Most vehicles don't even give the option like Jeep does. But sometimes it seems like the extra choices they give us come back to bite them given the confusion.
Lithium ion batteries charge easiest under 15% and hardest at 95%+. Jeep has normalized 15% to 100% as 0 to 100% and uses that hidden < 15% for hybrid operation.
