There are references to this in the Wrangler sub-forum, but I didn't see any in the Grand Cherokee sub-forum. Check your fuses! The fuse panel at the front passenger side of the engine compartment, pop the lid off (it has a red + battery post cover on it, you can't miss it) by squeezing the two marked tabs inward and pull the cover off. Then PUSH DOWN all of the fuses in the box. My friend who has a JL 4xE just happened to ask me if I had checked my fuses when I was telling him about some of the weird electrical gremlins I've had with my GC 4xE. We went out in the parking lot and popped the hood, took off the fuse cover, and sure enough more than half of my fuses were not seated properly, and a couple of them were barely seated at all and were able to be pushed in another 2-3mm! Can't say much other than WTF?!? I saw on the Wrangler forum that some have reported their fuses working loose again over time from vibration, so might need to be a regular "check" to perform on the vehicle. I'll definitely check mine again in a few weeks and see if they've stayed seated or if any are working loose again. Jury is still out whether this will make any difference at all in solving mystery electronic issues, but definitely something to pay attention to.

Check Your Fuses in Grand Cherokee 4xE

Any advice on how to open the interior (under the steering column) panel? I didn't find any obvious release tabs, and it seems very firmly attached.
Unlike the fuses in the rear panel, which for my vehicle nearly all could be seated a little further into their slots. The engine compartment fuses were in better condition, only a few needed to be pushed down.
Jeep - if you are listening, is there a valid reason for not having the fuses fully seated?

If it's like the Ram I'm working on today to install a light bar and CB, there are two screws at the base of the dash under the steering wheel, above the pedals. Remove those, then pull gently and the clips will release exposing everything under the panel. I'll take a closer look on our 4XE this evening, when I'm home.
What is mod PMI? I am about to pull Fuse F19a and B I can't stand the Pedestrian noise.
For the under the steering column fuse block, it is behind and to the right of the black plastic panel and can be accessed by getting the gray fabric/cardboard out of the way, by detaching the push fasterner near the center console. You can then reach up into the fuse block. Several could be seated more firmly in my vehicle. Getting the push fastener back in the right spot was a little tricky, though.
Curious as well. The only thing I can find is that it is some kind of sensor.
Good question for @Mllcb42
- Interior Power Distribution Center - many of mine were not seated fully.
What does that mean? You have to unscrew the one in the front?
As MCW66 explained very detailed "For the under the steering column fuse block, it is behind and to the right of the black plastic panel and can be accessed by getting the gray fabric/cardboard out of the way, by detaching the push fasterner near the center console. You can then reach up into the fuse block. Several could be seated more firmly in my vehicle. Getting the push fastener back in the right spot was a little tricky, though."
So i checked the one in the engine compartment, rear left and the ones under the steering column. I would say 90% off all fuses/relays i was able to push further in to seat fully.
At least in regards to the Wrangler:
If you talk to some of the techs at Jeep, they'll tell you that they've done some studies and determined that the loose fuses aren't an issue and don't actually cause any problems, so while it may seem like a problem, it isn't.
I've seen way too many anecdotal situations that were instantly cleared up by reseating fuses to believe that's the case.
I do think there's a possibility that the fuses are fully seated at the factory and they work themselves loose due to vibration. I've definitely had some work themselves loose from driving after I went in and fully seated them, so that's a possibility.
Wonder what the people who make fuses and fuse blocks think about that? I bet they are in favor of having the fuses fully seated. There's no way that my vehicle had multiple less-than-fully seated fuses at less than 1000 miles due to driving.
They probably would say that because there is a spring tension connection that holds the fuse in place, there is an acceptable range of seating depth that would still meet the requirements for electrical contact. It's not like the fuses don't connect with the electrical contacts until they're fully seated.
The important question is if the fuses are either getting far enough out that there is insufficient contact surface area or if the spring tension in insufficient so there is intermittent contact at times.
Good points. I would speculate, however, that Jeep gets the fuse blocks and fuses from a supplier. If Jeep goes to the supplier and says, hey, we are having problems in the field with loose fuses, the supplier would want to understand the condition of the assembled fuse blocks in the factory, and to understand 1) if they were installed properly, or 2) if they were coming loose due to some other cause (vibration during transit to the dealer, or driving, etc., or 3) if bad design of the fuse block that allows vibration to let the fuses move. I am reasonably sure that if the root cause was the assembly process and failure to fully seat the fuses, the supplier would point to Jeep and say you aren't assembling the product to specification, which (I surmise) calls for full depth seating. The supplier may say that there is some tolerance, but that the recommended process that we will stand behind is that the fuses are fully seated.
One variation is that Jeep isn't doing the insertion of the fuses, but the supplier or another outside contractor performs this step. At any rate it is Jeep's problem to identify and solve.
The issue there is that from what I have heard, they seem to believe there isn't a problem and that the loose fuses aren't actually loose, they're doing their job just fine.
If we assume that is true, that the fuses being not fully seated is simply within allowable tolerances.
Anecdotally, I disagree, but I don't know what actual data they have.

This has been an issue for every Jeep I have owned going back to a 2012 Wrangler.

I’m on my first jeep did not know this was common. The difference between craftsman ship from American to foreign is night and day. I have 20s on my jeep you can feel the horrible cutting of the rims. My detailer said GM is the worst but man was I surprised to feel the rim so wonky but looks absolutely fine. Realize a lot for creeks and pops on a Jeep than any of my previous cars. But overall pretty happy as long as it stays running. We do a 30 day trip to the dealer I’ll be leaving Jeep. I don’t have the patience as some on this forum.

Everybody's experience is personal to them. My wife wanted a Mercedes. Got her the large SUV. Had a ton of expensive repairs over the time we had it. But she loved the star! We replaced it with the smaller SUV, the size of the Grand Cherokee. After a few years and many expensive repairs, she said she wanted to return to a Grand Cherokee. The only thing I loved about the big Mercedes was the immensely powerful V8. That thing pulled so hard, it felt like a unlimited well of acceleration. Doing 80, give it a little rein and you were pushing 100. I am not a glutton for punishment, but then I have never been punished by my Jeeps.
I might be singing a different tune when I have the 4xe for a while. It is not my first Jeep, but it is my first hybrid and a fairly new drivetrain for the brand. Time will tell, in any case I have had enough good luck over many years of Jeep ownership that I know what to expect over-all. It may be my last hybrid, but I doubt it will be my last jeep.
