Bubbles in Paint at Door Hinges

[SH556JL]

Good luck all with your repairs! It never seems ends with mine! This will be the 3rd paint corrosion issue requiring yet another trip to the dealer and a few weeks in a loaner. This time it's starting on my tailgate. When will the hood go? What will it do when I'm out of the corrosion warranty? I'm almost just done with it.. getting pretty old..

Has the area been repainted before or is that factory? You can see where it wasn’t completely covered when it was painted, painted with the hinges on and can see primer around the edges of the hinge. Not very good coverage with base coat or clear... What I am afraid of with my new Jeep, is eventual corrosion because of the poor quality (and/or steel bolts going through aluminum). On just about every hinge, I can see a bit of primer and look real close, raw aluminum. Didn’t notice it first, but sure do after I waxed it and now can’t unsee it.

I had the dealer look at my Jeep and waiting to hear back. At the very least it’s documented...

The tailgate is factory paint. Before my hinges and doors where re done they looked the same as yours. I noticed the poor coverage like you state on my first wax with it. My hood looks the same as well..

My tailgate hinges are worse than any of the doors. Like you I worry about when warranty is up & it makes me want to unload it too. Did bubbles ever reappear in areas they fixed or just new locations?

I do not recall if this has been asked…. But here goes…

Does the bubbles/corrosion seem to impact certain colors more than other colors? Just curious.

I have a question that may or may have been answered in this thread. The doors are aluminum, how are they rusting?

it’s corrosion from dissimilar metals being in contact with each other. Aluminum doors with steel screws and hinges. You need to isolate the two metals in order to avoid this galvanic corrosion and apparently Jeep doesn’t understand how to do this yet.

I just finished filling out a quality survey from Jeep. I went pretty hard on them about the paint issues. I don't have bubbling/corrosion yet but every time I wash my Jeep, I seem to find yet another place where the paint quality is subpar. This last time I noticed the area under the hinges on the rear gate are really thin; I can see the bare aluminum through the clearcoat. I have an very small area on the passenger rear quarter panel with bubbles. The bottom of my door hinges look like they might be on their way to bubbling at less than 15,000 miles. I could overlook one or two of these things but they're starting to pile up fast. The survey asked if I'd like someone from Jeep to contact me. I will point them to this thread if someone actually does.

welp I spotted this today in my 2021 JLR.
First paint bubble or a small factory imperfection? Or is it too early to tell?
If it’s a factory imperfection I don’t give a shit honestly I’m just scared it’s corrosion

I appreciate any feedback,
Thanks!

Top right looks like its bubbling above the hinge!

Is there a TSB on this problem? It seems to be pretty common and a known defect.

Nice close-up. Looks like an imperfection in the hinge, that got painted over. At the upper right edge of the hinge the door does seem to be starting, though.

Hopefully you’re right and it’s just an imperfection. That’s really what I’m hoping for. I’ll post an update if it gets any worse.

i double checked that upper right side and it was all clear might just have been dirt as the Jeep needs a wash or I had a dirty camera lense. Thanks!

What you circular is def just a paint imperfection, I wouldn’t have it touched unless you notice paint bubbling in time.


I removed all my hinges one by one. I had all hinges powder coated black, and sprayed fluid film on the bare metal on the doors as well as the steel bolts.

Does anyone have the latest copy of this TSB? The latest I could find was 2019 stamped.

I decided to go to the Chrysler dealer today to see what they had to say. On closer inspection, I found that 7 of my 8 door hinges had some level of blistering under the paint, either on the hinge itself or on the raised flange of the door panel. The tech at the dealer took photos of each area, and said that I was the third 2018 Jeep today with corrosion. He showed me the dozens of photos on his phone. His next step is to file a claim with Chrysler.

What shame! I’ve babied this Wrangler since new. I’ve coated the underside with Fluid Film precisely to protect it our notorious road salt. I don’t off-road, keep it garaged, and hand wash frequently.

I’ve got a feeling this is a huge problem across all JLs and JKs. I’m going to look more closely at the next “jeep-up” event.
