I think I saw a post about this somewhere, but I can't find it now (maybe it was in an unrelated thread)....

The left wing support is lifting off of the trunk lid slightly on the left side such that I can see what looks like foam underneath. Has anyone tried to address this themselves? It's not clear to me without taking it apart what the issue is. Is it an adhesive issue, loose fasteners or just a bad fit to the curvature of the trunk lid? I'd ask the dealer to take care of it if I had something more major to bring it in for. But if it's an easy fix, I wouldn't mind doing it myself, so I'm curious what others have done. Thanks.

I reported this about a month ago. I have not been successful at simply pushing it down as others reported. I tried wedging a credit card or two to hold the trim piece down overnight against the tape, but after a while, it popped back up. It is held on with two sided foam tape. Think only fix is dealer or getting the tape from dealer and DIY. Odd that only left side issue has been reported. Right side is fine.

Hi could you please post some pictures so we can see what it looks like?
Thanks

I can report the same thing. Since everything is black it all blends in and is not noticeable but I'll ask the dealer to look at when I'm there at some point.

Mine are not down that tight either. Probably you could just use some double-sided tape and save the dealer drama. looks like a design flaw. carl

I saw a couple GT4s at COTA with black uprights and the trim piece on the drivers side looked like it was hanging on by a thread. The shape of the piece does not look to be the same shape as the body surface it is supposed to mate with - not to mention it's plastic!!! WTF??

Mine were coming up even before delivery. My dealer contacted Porsche, and were told that those pieces needed to be replaced. So, the dealer has had them on order for the past two weeks, but still no idea when they will come in. Also, installing them will require R&R'ing the wing -- not very happy with that idea. I may just try using some 3M trim tape, and see how it goes.

I agree that it looks like a design flaw. Those pieces are definitely not shaped to match the curve of the decklid; now that mine have come up on both sides, they actually look like they were made with flat bottoms. Maybe Porsche thought they would form-to-fit over time, but it's not working out.

Why would this only affect the driver's side? Assuming that both sides use identical trim pieces and the hatch itself is symmetrical along a longitudinal axis, then why would an improperly shaped trim piece only cause a problem on one side? As for replacing the part, I wonder if there's actually a revised part or if Porsche is just providing a replacement identical part thinking that the existing example must have been defective as opposed to a bad design.

It's held on with tape....unless they have a completely new design - i.e. different shape, then it will probably do the same thing again.

Mine has not come off...yet. However, I would be worried about water collecting underneath if it did. Is there proper drainage to prevent rust, etc?

I decided to take a closer look at those fillet trim pieces, earlier this evening. They are held down by double-sided tape, as previously discussed. However, the pieces actually do match the curve of the trunklid pretty closely. So, the reason they keep coming up is not because of how they are shaped.

It turns out that there is a rubber seal underneath each fillet piece, and it's the seal that is causing the fillets to come up. The seal is a fairly tall ring around the base of the wing support, and looks like its made out of EPDM foam. This seal sits on the base of the wing support and presses up against the inside of the fillet. Depending on how the wing supports are installed, there may not be enough room under the fillet for the seal, and the seal pushes up on the fillet, eventually overcoming the double-sided tape.

BTW, it certainly felt like those fillet pieces are actually cast aluminum, like the wing supports, and not plastic as previously surmised. They feel and sound like painted metal and not plastic. So, maybe not quite as "cheap" as we had thought.
