Farewell Jeep and CJDR

[ShadowsPapa]

The only thing I see you did wrong was not set it on fire over a year ago.

Dude, you and I totally know the REAL cause of the leak, corrosion/bubbling paint and messed up interior. Need I elaborate?

A bit of misinformation or misunderstood information there.
It takes moisture. If there's a good seal between the parts, like paint, then it won't be an issue.
If the joint is sealed from water, there can be no galvanic reaction.
The galvanic corrosion is a local corrosion and is, therefore, limited to the contact zone.

I have an aluminum car hauler with a steel hitch bolted to the aluminum frame.
The ratio of the surface areas of the metals matters. Check metal fab and finishing sites for details.

Are the back sides of the hinges totally bare, clear steel and not coated in any way?
There's nothing on the door skin at all - it's plain shiny totally bare aluminum just like it came off a roll?

Check metal finishing and similar sites for good information, not Jeep forums

The hinge plate itself has a black coating. The door itself is bare aluminum before having the hing plate bolted on.

The leak is from the plastic window frame cracking. There’s a TSB and updated part number out there. Don’t settle for a homemade fix.

Yes, I’m fully aware of the cause of the leak. I retired after 22 years as a repair/rework specialist for BMW, specialising in body work and paint less dent repair. My “homemade fix” is absolutely better than the dealers fix, which seem to have a lot of issues. It seems like they are tearing up a lot of the hard tops trying to repair them. I learned a long time ago, dealer techs aren’t always as great as you would expect, unfortunately.

I currently own two WW2 produced jeeps. So not getting rid of all my jeeps anytime soon.

I’ve got a ‘46 CJ2-A. Can’t beat the old school stuff

I officially got rid of my JT. Nothing but a dealer queen. 3 right axle shafts, rear window leak and scratch up your hard top replacing because of the crap design, slit seat leather from factory, severe wobble when going over bumps. What really put me over the top to get rid of it was finding out all my hood and all 4 door hinges all had paint bubbling due to their garbage painting process. 1 year backlog on doors and hoods because of the strike. Also nearly got stranded and placed in harms way on the highway when jeep went into limp mode because of a throttle body fault. My hard top also had whistling noises in the winter before seals wear out. But honestly who wants to pay 58k for a jeep and have to repaint all hoods and doors at the lowest bidder body shop Jeep can afford. It will never be as durable or good as factory paint. Most people have the paint bubbling come back after 2 years. So glad I got rid of this POS. Never touching a CJDR ever again. Good luck! Get rid of yours while you can because your hinges will corrode eventually. Took 2.5 years for mine. My buddies had his JL repainted and after 1 years it’s all bubbling again because of dissimilar metal corrosion.

I feel like you might be the guy that doesn't actually like anything but just dislikes some things less than others. What part of the Northeast are you from?

The only problem with my JT is not being able to take it camping nearly enough.

My 21 never been to the shop except service my paint is beautiful!! Actually my factory paint is perfect (maybe couple offroad scars) on all 3 of my Jt's and my Jl and both my Jk and Tj? But if I had issues I'd be pissed to!! I think you might be better suited for a Ridgeline? Buy Felicia

I had an Audi A8 like that. It was in the shop every month with another problem. Traded it in for a Grand Cherokee in 2011 and the rest is history. Love my Jeeps.

What kinda deal did you get on it? They’re offering some pretty tempting stuff at the moment

 

[PsyRN]

definitely got a bad one out of the bunch. must've been made on a Monday after a weekend bender. I've had none of those issues after 4 years of ownership. not even the bubbling paint.

 

[Gren71]

I have no data to back it up but i truly believe 21 / 22 models have the most issues. All the bs cv19 restrictions and “supply chain issues” ect. Ect. Makes me believe corners were cut intentionally and unintentionally and the end product suffered.

11-12k off window sticker.

Well what do you want from us, an ovation? You got a lemon or you don't know how to take care of a vehicle. It happens. Same can happen with any vehicle. Good luck to you.

I try to totally avoid that sort of discussion over there - some of the JT folks will know the obvious reasons.

The hinge plate itself has a black coating. The door itself is bare aluminum before having the hing plate bolted on.

My hinges are not steel.
The hood hinges and door hinges have no magnetic properties.

My 2020 had a gap between hinge and door skin.

Here's a pic of my 2020 door hinge - you could see a space, "somethings back there" -

Looks like my 2022 also has "something back there" -

It can NOT be galvanic action between steel and aluminum - these hinges are not steel. At least mine are not. Same for the door hinge half on my 2020 - it wasn't steel.

definitely got a bad one out of the bunch. must've been made on a Monday after a weekend bender. I've had none of those issues after 4 years of ownership. not even the bubbling paint.

The way modern factory shifts run, I'm not a believer in that Monday/Friday stuff (actually, never was as my father was a UAW member and worked in a factory several decades) but there's always bad batches of anything. Today, it's "lot #345534" or whatever that's involved, due to batch processing and things go wrong when that "Lot" is being produced.

No bubbling paint here, nothing around or on any hinge, the hood is perfect.
I'll never say never, but geesh, I live where they put salt brine in the roads and bridges when there's a chance of the temperature dipping to 33 degrees for fear of frost on things and they get that bring directly from the Dead Sea (it's not any climate stuff that's caused that sea level to drop, it's Polk County Iowa draining it to spread on the roads here)

It takes MOISTURE, any moisture, to cause or allow galvanic reactions. If it's a totally dry bond between the dissimilar metals that is sealed, there's not a problem. That's why in some of the marine chat areas you see people who have steel attached to aluminum without any problem they use a special sealer.
Also - pure water will do it but impure water does it better - add any metal chloride (and over 90 elements on the periodic chart are considered metals) and you get more reaction - it enables it.
So with the brine spray constantly hitting the sides of our Jeeps (the running board or power steps in combination withe "mud flaps" are a HUGE HUGE help that way - got pictures of the difference before and after) I keep watch anyway. Things rust here - anyone in Iowa selling a classic car and saying they have owned it all their lives - meh, likely has no frame left.

Since the hinges are not steel................. at least not the part on the door - then it's got to be something else going on. The only thing I could think of is if the door half of the hinge is a zinc alloy - then all best are off as zinc is so danged picky, when I do a thorough cleaning for restorations of alternators or wiper motors, any cast zinc parts start to "flower" and show spots within MINUTES of my taking them out of my cleaning processes.
So I'm wondering if they are using cast zinc parts, or some alloy, but it ain't steel so the people on the Wrangler side over there can stop claiming steel bolted to aluminum is the cause.
Back when I first started seeing talk of this when I had my 2020, I took my strongest magnets to the hinges on the doors and hoods and not even a slight attraction.

I have noted that it appears, there's an insulator between the hood hinge bolts and the hood hinge, possibly the same for the doors. Steel bolts through another material, use a sleeve/insulator. Note what looks like insulators around those hood hinge bolts.

My JTs have been white or gray with salt over several seasons - is it because I keep knocking on wood, or is there some other explanation, that I have not seen paint issues - YET?
