JL Ticking Time Bomb List

[Y2KFirehawk]

The longer I own the JL, the more I find out the ticking time bombs reactively versus proactively. Don't get me wrong, I understand no vehicle is flawless, but I keep taking paper cuts and want to get ahead, if possible...

1. 3.6 lifters - I think this is pretty well known. Doing regular oil changes and related UOA.
2. Aluminum corrosion - Door hinges, door bottoms, hood edges, etc. Was thankfully able to get repaired under factory corrosion warranty.
3. Fuse bus bar - Purchased and carry a spare
4. Bent door connector pins - Just be mindful reconnecting doors, straighten as-needed. Do have overkill/awesome alternative connectors in my watch list on eBay that someone makes.
5. AUX battery - Did the disconnect work
6. Collapsing brake lines - OEM replacements on national backorder. Replacing the front lines with aftermarket. Not sure if this is applicable to rear lines too?

What am I missing? This goes without noting regular maintenance items like diff fluids, trans fluid, coolant, etc.

1. It's not nor has it ever been the lifters that is the problem.
2. Does not affect the operation of the vehicle in any way.
3. They don't blow for no reason.
4. Don't break them? This isn't a problem for normal people. Broken wiring in the door jamb is more likely to occur from normal use.
5. This is how you get to #3
6. Not a common occurrence or significant problem by any means.

Any problem that could ever possibly occur is not a "ticking time bomb". You sound like you could use some time away from the internet.

In regard to the brake line collapsing, this is usually happen by lettings the jeep sit.
Unless OEM line are braided, you have a upgrade path available.
At the end of the day, adding a touch of when it break I will upgrade mentality can reduce the stress of ownership of a Jeep product

1. Stellantis
2. Jeep
3. Your local stealership

Thats pretty much the list

I know that to be true, not the smoking gun here.

I do like this mantra. Just don’t like surprises

How is it not common when the OEM parts are on national back order? Just a poorly aligned supply chain problem?
It’s not significant when the rotor turns red hot and impacts the stopping ability of a vehicle? I worry what may be perceived as significant at that point

It’s a normal thing. It happens all the time across all different makes and models. We stay busy on this stuff. It’s a very simple repair, and parts are available just fine.

This list seems more like consequences of not doing regular maintenance rather than nuances to the type of vehicle.

Brake fluid is hydroscopic, i.e., it attracts water. If your vehicle sits for extended periods, the water in the brake fluid causes corrosion in the system. Everything after that is bad. I like to change the brake fluid in my Vehicles every 2 years. I use a power bleeder for this because it means I do not have to have a helper.

Looking at your list, #1 is where I worry the most. I have 2 2020 Jeeps. One has ~60K miles and has needed cam and lifter work. The other is ~30K miles and has been trouble free. You can bet I listen closely to the low miles Jeep when I drive it.

FWIW, I strongly endorse disconnecting the aux battery. The best reason for this is that it makes charging, testing, monitoring of the battery simple as possible. I use a Eversmart (Walmart) H7 AGM Platinum battery that has a 4-year warranty and as much cold cranking power as both Mopar batteries combined. I have not seen anyone who has been using just one battery report problems with cab equipment because they switched to a single battery. In my case, I installed a Smart Start/Stop device to turn off the Start/Stop system which makes the second battery a non-issue.

Hyperbole is the word of the day here. Lol.

Honda currently has OEM parts on back order.

Thanks ya'll.

It’s not a bomb, but the oil cooler leaking is a common issue.

Item 1 is an issue, there’s 13,000 cams on back order with Mopar “a national shortage”, mellling wouldn’t take an order. I do oil changes every 5k, minimum off-roading, We’re not at fault here same for item 2.

Good points! The oil cooler was replaced with a Dorman unit prior to purchase. But as other noted, it's slightly leaking now due to the Dorman seals vs. OEM seals, which others provided great info on.

I solved corrosion by taking off hinges and painting bare metal then reinstalling with RTV to make it water tight. So far so good!
