I have over 15k miles on my 4xe, and the driving experience is great. The extra weight of the battery actually makes it feel more sturdy that a regular Jeep, with a lower center of gravity, and the extra power is great when you punch it.
I bought in 2021, so I got that sweet $7.5k back on my taxes for last year. It was super easy - just a couple of extra fields to fill in on TurboTax. It was before they raised the 4xe prices, so with the tax rebate mine was actually several thousand cheaper than the same options on a regular Jeep. If you lease, the $7.5k is immediately applied to your lease by the dealer, so your payments will be a lot lower than a normal Jeep. I believe you need to buy this month, as the tax rebate laws change in 2023, and you may get less or nothing for the 4xe after that.
Many people's use case makes a 4xe not make sense. You really need to have a short daily commute, and a garage or driveway spot where you can plug in every night. I didn't bother with installing an outlet for a Level 2 charger, which would charge it in about 2 hours. I plug into a regular outlet with the Level 1 charger that came with the Jeep, and it takes about 12 hours to charge. That works for me since it can charge all night.
My commute is 5 miles round trip, which uses about 20% of the battery on full electric. That leaves me with another 15 miles or so for running errands each day before I start having to use gas. I can go weeks without using gas if I don't go outside the city.
When I do take a trip, as soon as I get on the highway I switch it to e-save mode, where it runs on gas, and the battery doesn't lose any charge. The battery still helps out with extra HP when needed, but it maintains the charge level via regenerative braking. When on a trip, I never think about charging and just treat it like a gas Jeep. It does get about 1MPG worse than a gas Jeep on the highway, but I think that is worth it for the extra HP and torque. I more than make up for that with my daily driving that uses no gas.
Below is my trip meter after a nearly 2k mile road trip, followed by a month of driving locally on all battery. The other is more indicative of my usual mix when staying local. The .5 miles of gas was because I punched it hard enough once that the gas engine came on to give the acceleration I requested, even though I was in battery mode.
Charging doesn't seem to have much of an impact on my electricity bill either.
I am very happy with the 4xe and would recommend it to anyone that fits the very specific requirements for it to be useful.
