Cold climate = no go

Some may think -22 is extremely cold

One more time with me...

It being -22F outside and the battery cold soaking to -22F after fully depleting the charge are not the same thing.

Why are people in forum rooms for vehicles they have no interest in? Just saying, I have better things to do with my time.

San Diego now, from WI. Will retire in the mountains somewhere.

Will it start , on its own after after battery fully depleted in sub -25 f ? I believe your response was no . Don't know where you live , you may have mentioned it , there are alot of good people that live and work up here in temperatures you have described that don't have access to plug their vehicle in when at their place of employment . I believe there should be a disclaimer from jeep about the conditions that this vehicle will operate as designed and the need to keep it plugged in when temperature is below -22 f .

I had an interest in this platform . That is why I was asking for input . Sadly some people have very little common sense , either you have it or you don't . There are some that didn't or haven't checked the operating conditions this vehicle will operate in and will be 60,000 deep into a vehicle that will not operate , on its own in what some call extreme winter conditions .

Depends on how long it's been sitting in sub -25F. Time is the major variable here. If you need to leave the vehicle sitting out in sub -25F for a long enough period of time to fully drain the battery and then cold soak, yes, it wouldn't start. We would need some more information to determine how far away your leave it out overnight use case is from the use case where that's an issue though.

Living in that climate doesn't mean that you're going to have to leave your vehicle sitting out that long.

If you live in that climate AND have a unique use case that would require you to leave the vehicle parked in that situation long enough to fully drain the battery and then cold soak, then yes, this isn't the car for you.


You are taking a certain environment, layering on a very limited use case, and then applying that situation to a much larger demographic group. That is the disingenuous part.

Weren't the summers down there hard to get used to ?

Kind of. I found the W Texas summers a lot easier to tolerate than the northern winters, though. In this part of TX, humidity isn't an issue. Even on a 100 degree July afternoon, if you can get into some shade, it's not all that bad.

Seems people from the north have a hard time adjusting to the heat , kind of the same when people relocate here from the south adjusting to the cold . With modern fabrics and water proof options I can put more on to stay warm , but in the heat you can only take so much off .

Don't get me wrong. By August, I'm looking forward to October each year. But in February, I'm not tired of winter.

Now, if you want to be critical of the job Jeep has done communicating the proper behavior of the vehicle and its limitations to those trying to learn before buying, I certainly can't fault you there.

if i understand this correctly, you've already ordered a non-4xe and have questions in this 4xe-specific forum to help you to decide whether the 4xe is for you. But you have already ordered your non-4xe? So you have made your choice, enjoy.

This is a 4xe forum and people are going to defend their vehicle purchase. It's like all the Bronco threads, people will defend their Jeep purchases.

I'm thrilled with my 4xe purchase. I plug in at home and at work. When the few -22F days come, I'll experiment and see how it goes. To be clear, I purchased a hybrid, it happened to be a Jeep. Most, if not all, hybrids will have some limitations in some very specific circumstances. That's ok, we will except them and adapt.

If you like, once you purchase your vehicle, we can come to your forum and describe the short comings of your Jeep to try to help you celebrate and enjoy your new purchase.

I hope you get your new Jeep soon so you can focus on that.

How is winter time a limited case ? As I said if you work for a living as alot of people do that don't have access to a plug in , as alot of people do . This vehicle most likely will not start under its own power . Therefore it isn't a vehicle that will be suited to this environment , unless you have a really long extension cord .

Winter time isn't a limited case. Of everything that I have said, how could you even come to the conclusion that anyone is suggesting winter time is the limited use case being discussed? Are you being intentionally obtuse?

Parking somewhere remote where you need to leave it for several days, without driving, unplugged in that environment is.

If you're talking about someone that doesn't have access to charging at their normal parking location, they shouldn't be getting a phev anyway, ignoring any of the cold weather conversation.

Ok then , I never said anything about leaving it outside in - 20 plus f for DAYS . I said leaving it outside for 8 to 12 hours without being plugged in , a normal person's work day . From what most of the posts say it's probably not going to start under it own power .

My understanding, based on other EVs/phevs that I've driven and read about is that for the battery to cold soak to -22F, it would need to fully deplete and then come down in temp.

Let's look at 2 specific use cases:

1. You know it's cold out and there's a temperature threshold that the vehicle won't start at if the battery is cold soaked. You drive in e-save to arrive at your destination with 100% battery state of charge. You park the vehicle and go to work. During your work shift, while the vehicle is cold and not plugged in, some amount of the battery charge is used to condition the battery. There is a time threshold where the entire battery would be consumed doing this and you'd have an issue. Because you were aware of the capabilities of the vehicle, you adjusted your driving behavior to account for the conditions and you were just fine.
2. You ignore all of that. You drive around in electric mode and arrive at your destination with >1% battery state of charge. You park the vehicle and go to work. During your work shift, the vehicle is cold and quickly uses up the trickle of a charge trying to condition the battery. The battery cold soaks. You go to leave and the vehicle won't start.

Understanding the capabilities of the vehicle and using it appropriately will have different outcomes. If you leave it out in the cold unplugged, eventually the battery will be unable to condition, and the battery will cold soak. The question is how long must you leave the vehicle unplugged, not running, in the cold. There is a 3rd use case:

• You know it's cold out and there's a temperature threshold that the vehicle won't start at if the battery is cold soaked. You drive in e-save to arrive at your destination with 100% battery state of charge. You park the vehicle and go to work. Your work shift is several days long. During your work shift, the vehicle is cold and slowly uses up the full charge trying to condition the battery. The battery cold soaks. You go to leave and the vehicle won't start.

In the 2nd and 3rd use cases, you'd have an issue. The 2nd one can be easily mitigated by understanding how the vehicle actually behaves. Learn to use the tool properly.

The 3rd one can't be. In that case, it's the wrong tool for the job.

One would need to do some experimenting/testing to determine what the actual limitations of the internal conditioning is and how much is done with the vehicle not plugged in vs plugged in. There is certainly more that is done while the vehicle is plugged in and the manual discusses limitations to the conditioning being performed unplugged.


Ideally, we could leverage someone on the forum here that lives that kind of environment with the vehicle already to do some tests; particularly leaving the vehicle unplugged overnight to see if it'd start after 8+ hours in sub -22F temperatures and take note of the state of charge before and after to verify how much, if any, battery conditioning is occurring with the vehicle unplugged.

I think it will be interesting when dark winter comes to the north how many issues will be experienced by folks with this vehicle . Apparently some people have never experienced below -20f the high and much colder at night for days and nights in a row . A vehicle turns into a ice cube very quickly in these conditions . Even with a fully charged battery if left out for 8-12hours , without being plugged in the main battery will discharge itself trying to keep it warm before that 8-12 timeframe and then will not start under its own power . Hopefully folks will not have issues , but if they do , hopefully they let us know how long the main battery will hold a charge while trying to keep itself warm at - 25 , without being plugged in .

What is the kwh usage rate of the battery keeping it warm?

That's a great question , I would think the jeep engineers have that all figured out with all the possible variables , maybe you should ask them .
