FINALLY saw my first corrosion case yesterday.

[wranglerrush]

On the hinges, correct? Not on the door skin itself?
Majority on hinges, but there are small bubbles forming on door skin. The 2018 friends wrangler was all door skin six inches up along entirety of two doors bottom. That was a few years ago before I saw it on any of ours. I thought his was from possible clogged drains or something in the door.

What about inside the hood - where the hood framework or skeleton has the aluminum skin crimped around it? I expect it on ALUMINUM where it contacts steel.

Yes, it is at the seem on the inside edge of hood, both sides almost identical. Small bubble forming both sides

My hood looks terrible. Tailgate has spots too. And of course the hinges. I'll try to post some pics later.

Among the Ford and GM people, they keep talking "contamination" or "chips" - we know that our hinges are very prone to chipping and once there's a chip, all bets are off. Any compromise to the paint's integrity...... be it a chip, improper PREPERATION, or any contamination.

Jeep people need to check in with the Ford people - yikes! Some of them look like they are rotted so bad, they'll fall off. Tailgates, hoods, nasty problems.
Ford replaces the whole panel.

And that makes me think maybe Ford also believes it's a contamination thing - either in the metal itself (the aluminum panels aren't pure and clean) or prep............

Ford Exploder with the issue ->

Sorry, somehow my reply ended up in your quote, not your words. They are mine.

I agree with the impurity of aluminum all manufactures are using at this point. Anything to save on the bottom line. Probably using recycled aluminum for everything. Make sure you rinse out your soda cans before recycling lol

It's easy to have happen - sometimes the forum's "quote" function is really slow and you start typing and it finishes filling in the quote. It's happened to a lot of people here (even me at times)
So I get used to looking inside the quote..

That is how my hood looks.

I'm not sure if the bottom of the tailgate can catch rock chips. It might be possible.

I've had a few F-150s and haven't had paint issues. Current one is a 2020 without issues. Knock on wood.

I really do wonder if that's not some of the issues - especially since it's a common statement in the Ford areas, and Ford TSBs say replace, don't repair. Hmmmmm. Shipping a whole hood, painting to match, not cheap.

We used to laugh about looking under the fender of a Datsun and seeing "Budweiser" logo on the underside.
So, where is the aluminum being sources? Interesting question.

What about the hundreds of thousands who do not?

A few guys on the forum without corrosion hardly represents hundreds of thousands. Factory defects on the assembly line affects a high number of jeeps. Your fixation with trying to say its not an issue is amusing.

It's an issue - but not to the extent some would have us believe based on internet.
A few without? Really?
Here's the thing - when someone has an issue, they complain, often LOUDLY.
When they don't have an issue, they say nothing.
No one goes to a forum and starts a thread "I don't have any issues!" and shouts it out over and over.
But have an issue - yeah, it gets posted, reposted, over and over, and told to anyone who will listen.
Psychology- something else we've talked about for years here - problems get magnified, lack of problems just never get mentioned.
Even if you put up a poll - the most likely to see it and respond are those with the problem. Those without won't even see it in most cases because they aren't looking for it.
So polls on forums are not even close to accurately reflecting reality.

It's the internet. it's psychology, it's humans. When there's a problem, people seek out others with the same problem, validation, support, or help in getting their anger across.

Sorry, but again, you are talking about stuff that's old old news around here, been discussed over and over. Forums are magnets for people WITH an issue, and magnifying glasses that make it look bigger or worse.
No one is saying there's not a problem! There is - Ford, GM/Chevy, Jeep, ANY company using such panels have or are seeing it. It's an industry-wide thing.
But it's not a huge majority like you believe.
Forum members are a drop in the bucket compared to the numbers of people who own Jeeps with aluminum panels. A fraction of a fraction.
It's a problem - yes, but not to the degree some swear because of forum post numbers.

It's not a "you WILL", it's a you "MAY" see it. Look for it, but don't expect it.

I have seen it in the MIDDLE of the tail gate.
FORD and CHEVY have had problems with it on their hoods for years.
But it's ONLY a Jeep problem - just ask a Jeep person on a forum.

I had some fun (I'll relate this to this thread after a bit) a couple of days ago when I posted the oil geek's video about zinc, wear and friction in a fakebook page. I chose that page because the people there listen to the wrong people and buy oil with high zinc content, and then add MORE and still have problems......... or swear the additive is what they didn't have problems..
I let the flaming go - and sure enough, I lit a hell of a fire. People were in there contradicting the guy, saying he's wrong and their engines must have that high zinc and there's no other reason and nothing else can fix it and so on. It was hilarious. Some of them would have argued with their MIT engineering professors! (all because of what they believed, their opinions based on forum posts, or because of one engine loss)

The relation - it's been my observation that many people come new into a forum and believe that others there are of the same mindset, the same experiences, levels of education and that there are no experts in a forum on anything. There are no professors, chemists, metallurgists, brain surgeons, aerospace engineers, wind tunnel operators, design engineers and so on. Everyone is the same so it's not possible for someone to know more on a subject they are very certain about because of forums posts elsewhere.
This is one example. They swear they know what it is, and it's JEEP and so on. They'd argue with their college chemistry teacher. Heaven forbid someone may know chemistry, metallurgy, plating, solutions, processes and whatnot.

FORD has the issue, GM/Chevy have the issue. They may have resolved by now, but it's not quite as common as some would believe due to the fact that the internet and forums FOCUS such problems into a small space.
If 100 people in a forum have the issue, it's a huge, major issue. Doesn't matter that there are hundreds of thousands of the vehicles out there that do not have the problem. It's focused in a forum so looks a lot worse.

Now - if someone wants to try something, there's an easy way to prevent galvanic reactions real or imagined!
Look at the screws for the hood and door hinges - plastic sleeves preventing the STEEL bolts from direct contact with the NON-steel hinge. Allowing that bolt to contact that hinge, which is likely an aluminum alloy, perhaps a zinc or magnesium alloy, would be a problem.

So try this:

Door closed (to hold everything in place) Shim between the bottom of the door and the door sill or rocker panel if you wish with something padded to further prevent sag of the door while hinges are unbolted.
Remove the bolts holding the lower hinge to the door.
cut a piece of mylar in the shape of the back of the hinge, put holes where the bolts would go through, and put that mylar between the hinge and the door skin.
Also make sure the steel bolts cannot contact the aluminum alloy door skin - they ARE steel.
Do the same for the top hinge once the bottom is done.

Once you prevent electrical contact, it's impossible for any galvanic reaction.
Galvanic reactions also REQUIRE an electrolyte - water, etc. - so if it's dry, there can be no reaction.

The insulator can be extremely thin - it only needs to prevent contact.
Seeing the bolt sleeves should show that Jeep is aware of how metals react with each other. They ain't stupid.

Oh yeah. The old adage of "trust, but verify" applies to forums. And I'm not so sure about the "trust" sometimes!

I also owned a 1993 Chevy Silverado that had the paint flaking on the hood. It was a maroon color, which I don't know if that made a difference, but I see trucks of that year range of different colors that have no paint issues.
Point is, pain't issues have been going on for a long time among various manufacturers.

 

[wranglerrush]

Shameless plug….If you have paint corrosion and want to stop worrying about it, buy my soft top I have for sale in the classifieds and enjoy the open air

Yeah I'm not digging into all that. I will say, I don't base my info off of the amount of people that have the issue in a forum. You may think people are dumb, but most know you mostly hear the bad on forum so you got that wrong from what I said. Real world experiences and many other sources say, you can expect to see corrosion on these vehicles. Also, I could give a rats about "how many times a topic comes up" in any forum. Don't like the question/statement being talked about again? don't participate lol, simple. Someone should be able to ask what everyone's tire choice or what's the best oil as many times as they want. You don't need to reply.

 

[ShadowsPapa]

So far -
No paint issues
No engine issues (no tick, etc.)
No transmission issues, no clunk, no weird shifting

Will I ever see such issues? Maybe. It's possible.
I don't expect them, and I don't believe it's inevitable, but I believe it's possible - I keep watch. I ain't stupid. I don't believe that I'll always get perfect Jeeps. I'm never that lucky. They are designed, engineered and built by humans.
