Please Respond @jeepcares - Major Issue w/ 4xE Brand New

[IanNubbit]

Florida is warm. This is an issue in colder temperatures that doesn’t allow use of full electric mode. Hybrid is different than pure electric mode. Documentation says it goes approximately 21 miles on full electric mode at highway speeds. It seems that this is true only in warm climates. And it’s 20 miles of range before gas is supposed to kick in, not 200. We get zero miles on electric. It won’t allow pure electric mode to be used. In hybrid, it uses 100% internal combustion engine power, and zero from electric. I don’t know where your friend lives, but this appears to be an issue in colder ambient temperatures.

So, we gotta ask the dumb questions for proof of course. You went through the entire manual, read EXACTLY how to put it in full electric, you have the battery charged up, etc etc. there’s a good chuck of settings for the 4XE. Not only in the dash, the physical buttons, and the radio on top of that

Of course. This is our 4th plug-in vehicle. Fully charged, prestarted while plugged in, warm cabin from pre start, and very familiar with manual. It’s been read cover to cover more than once, and I specifically mean the separate. 4xE hybrid manual addendum. Do you have one?

Drove a number of hybrids when I worked for the state - Honda, Toywagon and so on. They don't really "Switch" or kick over to anything. They use both when power is needed, if the batteries are low they'll use gas more and more often. Pull up to a stop light in town, the gas engine shuts down until you press the pedal again. I noticed they used gas power much of the time, it was more electric assist in some conditions.
They don't run the batteries any specific miles and then switch over. A lot depends on hills and braking to regenerate or recharge the batteries.
These aren't an "either/or" where they'll run their limit on one and then switch to the other, they generally use smarts to decide what they need to do. Need to accelerate heavy - you'll have gas and the electric will kick in and give you a kick in the butt - at least those state cars did. In town the gas engine stopped and started quite a bit. I don't really recall them being on full electric a lot or for any length of time but that has been 6 or 7 years ago!



Are you stuck with that specific dealer for any reason? Are you too far away from another dealer? You don't have to use any specific Jeep dealer - you could bring it to Iowa and stop at Dewey and they'd take care of you even if you never bought anything from them. They don't seem to get hung up on that. We take two Jeeps to them and we didn't buy either one from them.

Traditional, non plug-in hybrids do typically work in a similar fashion. Plug in hybrids, including this one, have a pure electric mode that gives approximately 21 miles of range at highway speeds. No hybrid. This is a three mode vehicle. Electric, hybrid, and e-save, where it uses the ICE as a generator to charge the batteries.

I don’t personally own one but am a tech. While we don’t really get any in (we have honestly had 0 repairs in our shop for any 4XE just Oil changes) I’ve done a couple PDIs and training blah blah blah. So what IS happening? I know even doing PDIs I’m able to get one with only like 5% battery to drive in EV mode around the lot.

What have been the ambient temps in those few cases?

OK, thanks, I hadn't studied the details of these, I just recall how the others worked. They worked quite well (in their day).

I know nothing about it i was just quoting what he said and he's in North Carolina not Florida. It doesn't get extremely cold here either but it has been in the 20's a few mornings lately and he's told me she's getting really good gas mileage out of it. It's a 2021 Wrangler 4xe.

Ehh, 40s. A coworker does have one, I’ll see if she can test it. She’s not super savvy and really only has it for the tax implications

Are you saying it won't use electric power in hybrid or just won't use the all electric mode? It's been documented and explained as working as designed that it won't use all electric in cold temps as the oil temperature needs to get up to working temps. People have found buying the cold weather grill cover helps keep the temps higher as it cools too well in the cold.

How high do you have your heater set to? Also take a picture under the hood I want to see if there is a dedicated heating and cooling system for the battery.

There is dedicated heating a cooling for the battery, the issue isn't the battery temp but the ice side of it requires certain oil temps and to be run long enough at those temps to remove gas from the oil.

Jeep will tell you to run hybrid mode in the colder temps and just let it do it's thing. It's designed/programmed to not run all electric at certain temps. This has been talked about ad nauseam on the jl 4xe forum but people really want it to work a certain way so they say there must be something wrong and won't accept that this is the way it was programmed.

In that case Jeep really isn't going to do anything. My sales guy at work that sold me my gladiator also mentioned that to me after he bought his 4XE but I haven't had a chance to look through how it operates.

I was looking at the 4xe forums last week or so and saw that when it gets cold out it doesn't really use battery/electric to drive. As soon as it gets too cold it pretty much uses the ICE to get everything to a certain temp.

I see you're in CO, how cold is it there? I think the cab has to get above 60 at least and that HAS to use the ICE. Do you keep your 4xe in a garage? Heated? I've seen several people with this issue. Each instance I've heard the dealer says the same, 'it's how Jeep designed it'. Maybe it really is running the way it's supposed to, for shitty or not?

1 of the threads I saw in the 4xe forums had temps listed.

Yeah, then no offense, but she might not be a great resource. There are plenty of people who maybe don’t care about pure electric range, but we purchased it for that very feature, which is a feature of this vehicle. I posted this to get @JeepCares involved, as all other avenues have been exhausted at this point. If anyone experienced with this specific drivetrain has suggestions, I’m all ears. But random comments about hybrids in general aren’t applicable. Thanks though.
