Front Axle - NEVER has engaged - 2 plus years - wow how can this be?

[Bakerboy]

Please feel free to move if this belongs some place else.
What are the chances that the front axle FAD was never hooked up at the factor. Screen shot from dealer attached.
I am the original owner of the 2023 Mojave. I live on the eastern shore of MD and mainly drive on Assateague island or Chincoteague island or Cape Hatteras. So sand. I air down to 15-18psi depending on conditions. I've drive on the beach for over 40 years, Bronco's, Excursions, F250, F150, Ram's, etc. This is my first jeep.
I just figured it drove funny.

BUT... last week while in Cape Hatteras when surf fishing I parked in some really live sand. Needed a "tug" from my son's Ram to get out and just figured it was live sand. Then a day later, we went out by the airport and near the dunes I was fine, but got down near the beach and again, very live sand. This time I needed to be towed back to the dune line. I figure something went wrong and took to dealer this week.

Not sure if I should be upset that according to the technical report the FAD was never hooked up or enabled from the factory or impressed that in almost 3 years of driving on the beach this is the first time I got stuck?

Thoughts from the smarter people?

So was the connector to the FAD never hooked up or they saying the programming for it was never enabled? The latter I could say is possible.

Everything you describe then sounds plausible it was not enabled. As to why, that is anybody's guess?

The FAD delete and lockouts for Mojave did not happen until 2024+.

All of that stuff should be done prior to it being built - the PCM, BCM and so on should already be configured - unless some inside employee can say no, we do that on the line. Makes no sense to have to program in every little thing.

Is it possible that they had things prepped for 24 and changed some target date?
But here I am SPECULATING! Gasp! Speculating on the internet?

Is this a SelecTrac unit?

I agree as a course of normal manufacturing, it should not have happened, but I do not discount it being messed with post build either at the factory or dealership if they ran into some problem and were messing around with things that did not need to be messed around with.

Thanks… I guess Jeeps really do well in sand… impressed. Going to have fun when I actually lock it into 4x4

You just proved that even crippled, these things do extremely well in adverse conditions.

Imagine what it can do with the handicap removed from it.

It’s beer thirty on some assembly line in the world!!!!!!
BUT this should have been caught at the last step of PDI at least.

I think you are right on that one. I believe part of taking it out of shipping mode for the dealership PDI is to hook up a WiTech and double check the complete module topology and make sure each module is reporting the correct "as built" data.

And with most being sent out the door with 41 psi tire pressure when the door sticker says 36, we know that all of the other is also being performed as it should be.

I also wonder about the exact build date, when the 2024 FAD block-off went into effect and so on. Caught in the middle of a change?
Or, did the dealership do what most others do with the PDI - yup, looks good to me............
