Jeep reliability - most common issues?

[ShadowsPapa]

Did you, or are you going to check the wheel hubs for grease on the new one? Did you take photos of the hub job on the first one?

Yeah that was my other thing - I suggest the dealer was looking for an out, an excuse, for not finding the issue.
Sealed systems don't need to be full of grease, but dating back to the old days of the tapered roller bearing rear axles in the AMCs, up to the double bearing hubs in Eagle and Jeep - they need lube. They are sealed on both sides and don't need to be flooded, but they do need to be lubed. Usually grease in each bearing similar to how we were taught to pack front wheel bearings on our Camaros and Mustangs and whatever in the 70s. And they'll go a lot of miles.
As far as not needing grease - I refer back to the hub bearing blow-out in my car hauler years ago, fried everything on that end of that axle. Got it home, took it apart, took pictures, took apart another hub that was shipped with no grease and took pictures. I sent the pictures to the factory in Texas - they asked for my address and send me a whole new axle assembly - brakes, hubs, the works, by truck. All they needed to see was the lack of grease sticking out from any of the bearings.
I grease my trailer bearings annually, but you'd expect a trailer to make a short voyage one time and not blow up any hubs.

My doors and roof keep falling off. Jeep wont even try to address these major design flaws.

Also the gov should ger these things off the road. The windshild just falls down.

Do not buy. Save your family.

Its not just you!! Everytime i go offroad on a nice sunny day my doors and top just fall off too... Very strange indeed!

Glad you added the latter part, the "IMO", otherwise, I'd suggest asking the guys who have over 100,000 or even 200,000 miles on their "Italian made" diesels, and then check with the guys who have had cams replaced in their 2020 Gladiator.

Pros and cons to each, I can't say one is more reliable, it depends on too many factors.
In the end, I'd suggest both are very very reliable engines, the diesels in many RAM trucks, and Jeeps, without issues (other than emissions crap or the fuel pump) and same for the 3.6 - over 10,000,000 served, as the signs used to say under those arches.

Fair analysis! My neighbor has a diesel JT and has had nothing but problems with the engine according to him and i do see a rental in their driveway quite often. Lol. However, this could be one-off situation. Maybe he put the wrong fuel in it! Haha!

I did take photos to show the dealership, thats when they said it was normal not to be greased, but i cant find the pictures now. I do plan on checking the JT sometime soon.
