So apparently there is a TSB out for FCA vehicles using aluminum panels. Included is edge of hood (my case) and doors which is a common case here.

I don't think that procedure would make a permanent repair, since it does NOT address what causes the early-onset corrosion to begin in the first place. I'd like to know if the hood leading edge corrosion is coming from the backside of the panel or if it is beginning in a paint chip, pinhole, or scratch on the outer surface, then working in under the paint. If so, then a better primer is needed to prevent corrosion from getting under the paint when paint is chipped or scratched. Once that happens, the corrosion process has nearly perfect environment to operate in. As for the door hinge issue, it looks to me like there needs to be a non-metallic, air and water-tight "spacer" between the hinge and the door, and that the bolts need to be sealed inside and out to prevent any moisture getting under the bolt heads or creeping in along the threads. A better primer here would also be advantageous. The primer is either ineffective, or it may actually contribute to the problem due to its chemistry. The aircraft industry seems to be able to deal with this issue. Heck, Coors cans can last for decades in the outdoors after being crumpled and tossed aside.... and they are thin as a Bible page....

Add me to this list. Unbelievable. I am really disappointed in Chrysler engineering and quality. Never owned Mopar before was hoping it would be better than this. Between failing limited slip rear differential and crappy paint what’s next??? So sad as I love the Jeep thing.

Any known changes to 2020 models to prevent this?

What has me really concerned about this is the areas where corrosion might exist that we can't see. Like on the inside or backside of body panels or where the body tub is matted to the steel frame. Based on my experience with this so far, going to the dealer for a corrosion repair could be something that we will need to do every 6-12 months. Well...at least until our corrosion warranty ends and it's no longer covered.

It doesn't look like it. The Corrosion bulletin that Wranglerguyman posted above applies to Wranglers from 2018 to the Current model year.

All 4 of my doors and a spot starting on my hood. I love my jeep but I have had too many issues like this with it. I take extremely good care of my vehicles. Its disappointing. I just spent a week fixing all the frame and axle rust myself. I am working with my servicing dealer. Body shop wants NEW panels to repair it correctly.

AGREE!!! EXTREMELY disappointing. I am also meticulous with my vehicles. Wash/wax routinely and never let road salt sit on them for any length of time. After only 2 winters this shows up. Don't know what to do, as I am sure it will look terrible if they try to blend/touch up and I am POSITIVE it will come back anyhow. Good luck to you and let us know how it works out. Mine is at dealer now looking at this and we'll see what they say.

So I only read pages 1-3 and 6-7 but the rear quarters are ferrous, aren't they? How/where exactly did Jeep mate the two in the body and how are they attached together? Seems there might be a major area for galvanic corrosion going unseen?

I’m not sure if it’s galvanic corrosion. In my case, the front edge of my hood is bubbling up, the edge of my rear passenger door is bubbling up as well as 2 of the 4 door hinges. Apparently it’s a known issue amongst all FCA vehicles using aluminum panels. The Grand Cherokee forums have a decent amount of cases of this, which is where I found the tsb I posted a few posts back.

I wonder if adding a ground strap from the doors to the body and the hood to the body might help. I wish I could get the hinge bolts out without damaging the paint. Mine has no corrosion showing, but I expect that in will have in a few years, if not sooner.

I've seen old small aluminum boats and old airplanes with the paint weathered to metal with no significant corrosion. I think a yellow-greenish zinc chromate primer was used.
