Also, unrelated, they initially said they wouldn't re-gear my jeep for me. After some discussion, they said they would if it was a MOPAR kit. Does anyone know if the MOPAR has released the gear kit for the 4.56 gears yet?
Interesting! The dealership I went to changed out my gearing to 4.56 with the Dana kits I purchased from another vendor. Weird.

I’m guessing two things are going on. 1. My dealer lost a lot of staff last year (mechanics, technicians, service staff) and 2. I’m in MA where they probably don’t do many gear swaps. I’m still interested in regearing to 456’s.

If you’re in MA and looking for a gear swap (I may do the same at some point) you might consider a place like Off-road Elements instead of a dealership.

Mine is stuck too but seems to be stuck in the loud position. Got stuck with about 700 miles on it. 1600 miles now. Will have dealer look into it whenever I get the Jeep to the dealer. 2021 392 XR.

Just happened to me today. I have 900 miles on my 21 392. Any update on this? Did you get this fixed ?

Mine stills sticks every now and then. Just don’t have time to chase it down. I leave mine in sport mode 99% percent of the time so I rarely notice it

Just got it fixed yesterday. They replaced the vacuum lines and a faulty solenoid. Covered under warranty.
Would your service repair paperwork tell you what the part number is for that solenoid. The service manager couldn’t find anything at my local Jeep dealer. Just kept talking in circles about it

Unfortunately, it does not provide the part number for the solenoid. It indicates that the solenoid was replaced but only provides the part number for the active exhaust vaccum line (vac line part # 68484097AD). The service department is at Colonial Dodge in Hudson, MA. (978) 568-8000 if you want to try calling them.

Here's my repair paperwork.

Mopar parts search does not seem to include every part on the vehicle; only the common ones.

It could be the solenoid is the same as Quadrifoglio and other Stellantis vehicles.

The best I can do is 670002843 which is from a Maserati, but that part number does not bring up any results from Mopar. Probably it is a very similar part.

Otherwise I'm pretty sure the part number will be on the solenoid, if it visible without pulling everything apart.

I googled the part number on that invoice and found one mopar supplier that says the hose and solenoid come as a complete assembly. So took that part to the dealer and they said there is two newer revision numbers for it. So they ordered them. Guess we shall see
