Even if it does go in to 4A it will never use 4WD?
I'm not quite sure what you're asking. But when the serv 4wd light is displayed, the Jeep will be in 2wd and unable to use 4wd. It might be a software issue or a bad or damaged sensor among other things. Check out this JL thread where a temporary fix was made after somebody put a lift kit on and the ABS sensor was damaged. It'll help explain better than I am.

I’ve literally had it 36 hours. I’d hope it’s under warranty.
We're sorry to hear of this happening so soon in ownership, MisterPace! If you end up visiting your dealer and need an extra layer of support, please reach out to our team.

I dropped the 4XE with 120 miles on it off at the dealer yesterday. I've owned the JEEP 36 hours at the time of dropping it off.

They told me this on the phone today. "They got it in right away and it needed a part for the four-wheel-drive. There are only five of these parts available in the country, my Service Manager overnighted two of them here to make sure we can fix your car by tomorrow. "

I wonder what the part is as they haven't told me yet. Should these vehicles require new parts this quick?

I replaced mine. It was bad from new. Bought fad module and 10 min install. All good now. I plan on fixing bad position sensor on old fad and modifying it so I can run 2wd low range at boat ramp. I did this with Ram 2500 cummins, and jeep crd too.

I drove my 4XE home, charged it, and when I started the next day. I get the message SERV 4WD under the battery percent. Anyone know what this is?

Take it back! We had several erroneous messages when the entire system failed and had to be dragged out of our garage! They had to replace the entire Power Inverter Module! They need to issue a recall

We got this about a week ago, around 1700 miles or so (at our 200 miles a month use :D), it came and went a few times. Switching from 4H Auto to 2H Auto and it disappeared, I guess since you're not requesting 4WD. Had a couple of engagement attempts, where I could feel the front kind of trying to lock, I understand this subsystem is the FAD, (Front Axle Disconnect), and this could be the electro-mechanical part or the supporting electronics.

Over a few days it got to where it pretty much comes on in 4H, so been using it just a little in 2H, the traction control disable light came on one time when I was backing up and it was trying to engage, but that's probably a phantom related issue, it disappeared with a power cycle and stayed off.

I did do a another round of seating the fuses/relays, I had done this preventatively about a month after we owned it. Also checked a specific harness someone on another forum said was disconnected and caused this issue, but it's firmly connected.

So I made an appointment :) We're going to drop it off in a couple of days, drives just fine so no sweat getting it up there (dealer is only ~8 miles away), hopefully this will be a quick fix per some other folks who have dealt with the same issue (and it's not 4xe specific).

Thanks.

I don't mind the service requirement, shit happens :) So I'm hoping it's simply a matter of quickly identifying the issue (it's apparently pretty well known, I even have some service docs to show them), making the fix, and getting the vehicle back.

Took it in yesterday at 2p, they called about 3:30p, said it was the "transfer case motor" which sounds like this service sheet someone posted:

Font Paper product Monochrome Paper Document



(I even showed this to the SA when I dropped it off)

However, the part is backordered without any projected availability (sad trombone), so we picked it up today, works just fine in 2WD mode and no sense in it just sitting in their service parking lot. I'll update when the part comes in - according to the document above, it's a super quick R&R, so maybe I can just wait when it does come in vs. another drop off.
