2024 JLUR X 4xe
Had both my electrical coolant heaters replaced.
(Part 68400740AD and 68443445AC)

https://www.jlwranglerforums.com/fo...em-cabin-cooling-or-heating-choc-p0e15.78068/

Also had two previous winters where I spent multiple months stuck in FORM.

Regret trading in my super reliable JK every time I step into this thing.
FORM doesn't bother me, since I'm not buying a 4xe expecting it to be a BEV (and I already own another PHEV and am used to the tradeoffs). I'm only after the torque and better in-city efficiency. Being cold in the cabin with a toddler and wife would be a major issue, on the other hand.

Yep. Hence my recommendation to avoid it in cold climates. It won’t behave like any other PHEV. I work closely with our Fleet department. We have plug in hybrids (Fords, Mitsubishis), none of those behave so radically different in winter than my 4xe. Parts failures, bizarre driving restrictions. Just not a consistent experience.

And it absolutely pisses me off to hear folks dismiss the cold weather issue as a myth.

I drove a 4xe up in NH during winter and it wasn't problematic, but there's definitely the "It's a Jeep Thing" component to parts failures, sounds like you've been hitting them all. When you're not having a coolant system issue, how's the cabin in winter? My experience was fine, but just want to make sure I'm not missing something.

In MD you don't get anywhere near the cold places like MI/NH/ME/etc get, and aside from FORM complaints (and the random Jeep issues) I haven't seen much negative regarding cabin comfort, which is why I was curious about your experience. I appreciate the info!

I love my 4xe. I’ve tracked every fillup since owning in May 2021 and I am averaging 60% of my miles on electric and 40% gas. With local utility rates, each mile on electric costs me 1/4 what that mile would on gas.

Throw in that it’s a Rubicon that does 0-60 in 6s = it’s stupid fun on and off road.

While you may have had real issues, it’s certainly not the norm.

Two Michigan winters here, lots of winter camping, never had a single issue with excessive FORM or going into electric mode above -12F.

I don’t try and pretend this is a BEV, and it does everything I want and more.

This is one datum point, as is your experience.

2019 Jeep Wrangler Rubicon Unlimited
My wife and I wanted to like the 4xe. The back seats not folding flat was a bit of an issue for the 2 dogs. My head hits the roll bar when seat is back. The transition from battery to combustion when accelerating ain’t the best. These issues don’t exist on normal JL. The prices of jeeps are insane. We ended up taking our time and found a 2019 JL Rubicon with 50k miles for half the cost of a new Rubi. In the northeast, we need combustion to keep us warm in our jeeps. Good luck with your decisions.

Yeah. After reading everyone's comments, I am not ready for the "4Xe experience." Especially given that I live in a cold climate, and a lease would have me stuck with it for three years.

My dealer is terrible to boot. I cannot imagine putting myself in a situation where my 4Xe needs ongoing warranty work and I need to rely on those sons of bitches.

I will hold off and look out for a used 2-door with the right miles at the right price, or place a factory order on a new one.

In the meantime, I will continue enjoying the Mini.

There is cold, and then there is cold.

I think the major problem with the 4xe and cold, and FORM, is people not selecting the drive mode they want to drive in, and keeping it in Hybrid causing too many unnecessary engine starts to occur. The way I drive the 4xe is I drive within the limits of the electric motor, which can power you to upwards of 60mph, some people said they go 70mph on electric, I never had any interest to test that, if I know I'll go beyond the range I'll choose to run the gas probably for the entire trip.

There really is absolutely no reason to leave the Wrangler 4xe in Hybrid, if the vast majority of your trips are being done in electric, and your driving isn't erratic.

I live in Toronto("cold"), and never had the FORM issue that a few people are describing, probably because I leave it in electric vs Hybrid, Hybrid seems to be recommended choice by forum experts, they claim because the computer is smart enough, and it knows best, and it's the most efficient etc.

The vast majority of my driving in "cold" Toronto is ⚡

For 2023 I did, 7,439 miles, 6,355 is electric, the non electric is mainly because of trips exceeding the electric range. 2022 was double the miles, with a similar ratio, I just never thought to log it.

A few times in the winter when it's -12c or colder you are locked out of electric, but at those temps you are better off driving with the gas motor to heat up the cabin in any case, for me the battery drain too quickly when used to heat the cabin. If I had a charger I would probably use the battery for heat.

When dealing with extreme cold that may be a different story, but extreme cold and EVs don't mix for the most part, some EVs do extreme cold better than others.

The driving experience is consistent if you choose how you want to drive, having the computer think how your experience should be, will give results you may not like.

PHEVs like Ford and Mitsubishi have more of an efficiency and range bias, vs the 4xe which is more about performance resulting in the 470 torque, and lower range.

This only happens when slamming on the gas pedal on a cold engine which isn't normal driving.

Luckily the 4xe have driving modes to facilitate erratic driving, if your driving style is more grand theft auto, then it's better to use the manual shifter, and stay away from pure electric driving, and always keep the gas motor fires up.

This.

I rarely use Hybrid mode. I choose electric for around town and then go to ESAVE when I jump onto the highway. The on/off cycling during Hybrid drives me crazy, especially since I changed to a louder AFE exhaust. Staying out of Hybrid also helps me avoid any short engine cycles with the direct injection system.

Selecting one of the two modes is just part of the rhythm now, really no big deal.

How do your fords and mitsubishis behave? We have a Tuscon PHEV. I prefer how the 4xe handles heat. The Tuscon uses the ICE in the background for the heater in any temps under 50. It pretty much runs the whole time even when I'm in "ev mode". Worse since its used only for heating not propulsion it never gets up to running temps. I hope Hyundai built in some sort of FORM feature or oil dilution will be an issue with these. Luckily I get ours up to running temps at least once a week so it shouldnt be too much of an issue. In my 4xe, I can drive in electric, turn off auto climate and set the blower to the lowest setting and still not have the ICE turn on. Sure my range is less but still I can drive without using any gas and have heat.

I had a sneaking suspicion you'd do this after reading all of the horrible things that happen to 4xe's. It really does feel like a toss up on if you'll get a good one based on the forums and group pages littered with different gripes and bad experiences. Again, I've had 2 of them (both '21s, both Geckos); my first was perfect, my current one not so much. So on that basis I'm pretty 50/50 with it. On the one hand they are fantastic for what they are. Anyone that expected these to get similar kinds of hybrid experiences to something like a Toyota were delusional to begin with; it was never gonna happen considering how they made compromises to make sure at the end of the day it was still a Jeep first, hybrid second. On the other hand, it can be a real pain in the ass if something in the hybrid system goes wrong since it's not exactly DIY friendly to work on those components.

I still stick by my original recommendation for you considering your local dealer isn't super trustworthy. You might consider jumping on a deal here at the end of the year seeing as it'll probably be the last opportunity to really get a kick ass deal before the market really goes tits up next year. I'm still working with a Broker locally on finding a regular Rubi to replace mine hopefully before new years. I'm fed up with dealers out here trying to give me auction value vs their full retail price for a swap; anyone that thinks that's normal is crazy considering how much they're struggling to move any inventory at all right now. If it doesn't happen, I'll just keep holding on and putting up with mine until the right opportunity to bail makes financial sense.
