Do I have a lemon?

[beginnerjeeper]

Hello, I'm new to owning a jeep, and I have a 2021 4xe just a year old.

Since the first day, it's had several problems (check engine light came on day two, completely bricked within two weeks, etc.)

I get very different outputs on any given day. I drive the same exact route, the same speed every day to work, but some days I will get home with 60% battery remaining, some days I will have used the electric charge entirely. Even with all other factors as similar as I can make them (no AC/heat for example). I expect a little fluctuation for things I can't control (traffic, temperature outdoors, weather), but a 30-60% swing seems excessive. I'm wondering if everyone else experiences this too and this is "normal"?

I also get extremely poor ratios. On a good day, I have about 25% of mileage coming from the electric battery in hybrid mode. Once the battery is used, I get almost no mileage from it anymore - essentially the only time the jeep acts like a hybrid is in those first 28 miles. After that it is only just using gas even in hybrid mode. I have tested both e save and hybrid and they perform the same after the battery is <1%. On an appx 400 mile trip, I had 19 miles of that as electric, everything else as gas. Is this the norm for other users?

Thank you in advance!

Welcome to the Forum, from Cave Creek AZ.
I really don't know much about them. But my Neighbor has one, and he tells me than he gets about 26 miles and then has to re-charge. That doesn't seem like much of a advantage to me. Then one has the electric cost to re-charge it. Hopefully, that doesn't add up to much.

E save hold and hybrid after <1% are essentially the same. Theyre also both hybrid modes where power is coming from both the electric motors and the ice and power is recaptured during regenerative braking. Also, the jeep is only rated at 21 miles of electric range, so you getting 19 sounds about right.

It's a huge advantage if you're like most people that drive less than 25 miles per day.

No help here either. From what I have read, I am not seeing the appeal to own one of these.

My decision was made a lot easier as I ruled out 4dr due to the weight as I will tow mine behind an Class C RV.

Good luck getting it sorted!

Ah, I guess that makes sense. But just dead weight for trips and off-roading.

Nah, that's not what happens at all.


After the 20ish miles, it just converts to being a mild hybrid. You still get the 375 hp/470 ft lbs, etc, you just can't run on pure electric.

This is the part that I'm wondering about. I don't seem to get any sort of hybrid experience after the electric is depleted - which to me hardly seems like a hybrid. Moreso a "hybrid up to 30 miles, then pure gas after". I'm just wondering if that's how it's supposed to be. I've seen screenshots on this forum from others who are getting more like a quarter of their trip miles are electric and I'm getting nowhere near that. (19/400 is about 4.75% only)

Let's be clear about how you're defining a "hybrid" experience.

The 4xe doesn't have a mode that runs on pure gas ever. Even in e-save, in hybrid with <1%, etc, when you demand power to accelerate, it will provide power from both the ice and the electric motor. When you brake, the regenerative braking system will recoup power via the electric motor. This is a mild hybrid operation.

When you have charge in the battery, it will operate at times on electric only. How much depends on what mode you're in. Essentially, you get electric only use until the battery has <1% soc, then you get a mild hybrid.

People that are showing much higher amounts of electric miles are charging repeatedly during the mileage range they're showing.

If you're going on a 400 mile trip and you're starting out with a full tank of gas and a full battery, with it set to hybrid, you would expect the first 20ish miles to be done on all electric and then the engine would kick on from there. You may find that on the highway or if you accelerate too aggressively, the ice may come on sooner, and you may see a period of use where the ice is on and you're getting more power offset from the electric motors, meaning you're using less gas, but showing less miles of electric only.

If you want to confirm that it's behaving as expected (although what you're describing sounds like it's working properly), on the hybrid pages in uconnect, you can see the power flow between the engine, motors, and battery to confirm that power is coming and going from the electric motors/battery as you drive around in the <1% state.

As for the break down of miles, it all comes down to how often you're able to charge. Mine shows something like 60% electric miles/40% gas, but that's because my daily commute is about 40 miles and I do about 25 of them on electric... and then I recharge.

Dunno about others, my cost of driving went from $400+ a month to almost $0, due to the fact I can charge most of the time for free.

The added weight makes for a much better ride IMO, plus the added instant power is a bonus.

Like buying anything else be an educated consumer, don't buy a DVD player to play mp3s, then complain it's crap at playing mp3s.

Well seems to me you have a lemon-yet you're not the only one had a trip last weekend-four of these new 4xe vehicles and two of them developed electrical problems one was literally towed out before we even started, and my good neighbor returned his about two months ago-something to do with the thing not maintaining a charge. Hopefully you find a fix if not the JLUR with 4cyl 2.0t is doing great. Keep the Jeep wave going.

electrical problems, you don't say, electrical problems seems to predate the 4xe.

Thank you for the reply! I have entire drives that start at <1% (have done this intentionally to test) and at the end, in hybrid mode, will show 0.0m from electric motor and the entirety from gas. These are longer drives 40+miles, so it's not that the drive is too short, or lacking braking to get nothing from even a mild hybrid operation. That's why I said it was showing only gas usage (I should have specified.) At that point there is nothing "hybrid" about it- it is pure gas usage.

The widely varying usage under near identical conditions is also making me question if something is not functioning correctly with mine.

Can you show us a picture of your driving history and trip reading for us to get a better idea of what is going on.

This is incorrect.

100% of those miles are hybrid. They just aren't electric only.


The 4xe never runs gas only. What you're referring to as "gas" miles are not gas only. They're hybrid where power is coming from the gas engine AND the electric motor as needed.


When the jeep shows <1% battery remaining, there is actually around 15% state of charge. It's constantly charging and discharging at this lower state of charge as it behaves as a mild hybrid.
