Hinge corrosion

And yet, some people have paid upwards of $140K for them (crazy market).

Your whole comment is riddled with logical fallacy, considering I just said I would like to see Jeep use a similar paint process. I could also be argued that changing the paint process over to one like BMW, Porsche, and others use would actually save Jeep money. For one, they'd have less paint related warranty claims (which are expensive), secondly if you watch the videos of BMW's and Porsche's paint processes, you'll see fewer people involved during the paint process (look how many people are walking that paint inspection line in the Jeep videos checking and fixing paint while the Jeep is in motion on the line, versus TWO people involved for BMW and Porsche at the primer step and TWO people involved at the paint inspection step).

Keep in mind, the starting price of some BMWs (228i Gran Coupe - $36,600) are fairly close to the starting price of Wranglers ($30,945), and I assure you that price differential is not mostly attributed to the painting process. Some well-optioned and fully-loaded BMWs built here in the U.S. at the Spartanburg plant are quite a bit less expensive than a loaded Rubicon, let alone the 392 (a well-optioned X3 sDrive30i is in the $55K range).

But, sure, a better paint process would almost double the price of the 392... 🤣🤦‍♂️

(You know it costs $11,875 to have AEV custom paint the entire Jeep - inside and out - by hand in a custom color, right? That includes them removing basically everything on the inside and outside of the Jeep, and removing some parts around the outside of the engine bay, and then reassembling...)
$11,875 well spent.
 
No one with a 2021 have any corrosion yet? Maybe the painting process was better on a 392?

Sorry but there is no way I can for a second believe the painting process for 392 is any different. I have found flaws in mine that I would have never expected. Two runs behind the spare tire carrier the worst.

I’m not naive to actually believe the painting process is any different on a 392 but I would believe that 2021s should be showing corrosion by now. Plenty of others on Facebook groups and JLwranglerforums do.
 
Going to use Boshield before winter along the edges of the hinges and reapply in the spring.
 
When I had ppf installed, they noticed the right rear window panel was repainted (factory work for sure since Granger didn't do it). I guess robots have bad days too.

The 392 crowd might have delayed corrosion because it seems most are parked in doors. I check mine about once a month.

Might be true.

FWIW how could they tell it was repainted? More/less orange peel? Color off?
 
Interesting.

Just like taxes and death, hinge corrosion is inevitable
Do you think hinge covers would minimize the damage? I’ve seen a few posts about them, can’t remember if it was here or JL forum, but it seems that people were getting them mostly for appearance.

No.
 
Figured as much, but this being my first Jeep, thought I’d ask.

It could go either way. My train of thought on the hinge corrosion is that it is poultice corrosion, not galvanic corrosion. If my train of thought is correct, then moisture getting under the paint is the culprit. In that case, hinge covers could either prevent water from getting under the paint (unlikely since they aren't water tight) or they could trap water on the paint seam between the hinge and the door, promoting moisture getting under the paint.

Beyond that, I think they look stupid.
 
It's crazy that this still occurs after having to pay its dealerships TONS of warranty claims to repaint who knows how many Wranglers.

I am guessing the bean counters at Stellantis did a cost benefit analysis and found it less expensive to pay dealership warranty claims for body and paint work than to redesign/engineer out the root cause of the hinge corrosion.

If there is no paint between body and hinge, maybe the best thing is to disassemble, clean, zinc chromate prime, paint and possibly even put some barrier film between?
 
Hi all,
Can I get a sanity check? So for the 2023's are the doors and hinges made from aluminum or are the hinges steel?
Thanks in advance.

For 2023 Jeep supposedly installed a zinc plate between the doors and the hinges to halt corrosion.

Love to see pics of that. Maybe those that have a 23’ could check?
 
it's been said already the hinge and door are aluminum. The bolt is steel. Putting anything between the hinge and door makes no difference if you're using the same untreated bolt.

Genright uses a Stainless Bolt which may help prevent the chemical reaction between the aluminum and steel.

I'm wondering if something like anti-sieze or another coating on the threads of the factory bolts would assist with preventing the reaction.
 
Trying not to be sarcastic but is Jeep the first brand in automotive industry that tries to put aluminum and steel car body parts together? Wow, pioneers since 1941. 🫡
