I think water is leaking in not from the hoses (even if they may have some wear points or holes) but the gaskets they attach to in the trunk channel that the water runs around (not the attachment to the trunk lid). Remember that water always flows downhill. Without spending much $ at all I'd do what I have done on other cars where this has happened with such seals. Clean up all the areas surrounding those gaskets where they meet the metal with a tooth brush and get all that dried up gunk and crap out of there... I can see it in your photos. Then you have 3 options to seal around that space where the gaskets meet the metal. You can go with a silicone based caulk that won't last very long, a butylene caulk that will last a long long time but is an absolute mess to deal with and get rid of if it doesn't solve the problem, or some cheap Green synthetic Bearing Grease that is waterproof. I'd personally go with the Green Grease that I've used to fix these problems... Stick your finger in it and smear a bead of it all around that gasket and I bet it never leaks again. If you have to go to further other measures it can be cleaned out pretty easily to try something else. I don't think it is coming from the flexible hose. In fact, if you look at those hoses and where they flex at their lowest point you could pole a hole in them to let any water drain out of them and it wouldn't make it into the car, it would run down the left and right trunk channels.

Here's where I think it is leaking and could start leaking on the other side in yellow... clean and grease all around these gaskets... I bet the problem is fixed for a LONG time. But, as always, I could be wrong.

Quite frankly, after seeing your post I'm going to check mine, clean them all up and put a bead of Green Grease around mine as a preventative measure!

Deapsea21, you mentioned in your OP that the strips on the roof were removed for repainting and then mentioned later in that the one looked like it was 'up' some. Is it possible there is a hole in the roof metal in the valley (maybe from rust)? How hard would it be to remove and inspect that location where the strip is at for rust/hole/damage? Oh, check this if sealing with the grease doesn't stop the leak (or if you remember any bare metal when you painted them maybe check it now before you seal?).

Body shop did it. I don't know how to remove those strips on the roof but I might do that first before sealing it. How do they come out? I don't want to break them. Thanks for your help!

 

All great tips. I feel like that night be the culprit if not the strips on my roof I posted before (the one that is slightly raised).
I'm gonna send you a PM tonight after work cause have a couple of questions you might be able to answer fairly easily. Thanks!

 

Regarding those roof trim strips that were removed. I can't be sure but I guess there could be a hole that rusted underneath it in the channel. However, if a hole had rusted in that channel I would think the car would display some significant areas of visible rust elsewhere. I've never pulled the channels on my car so I can't say what it could look like under them. A quick search on-line seems to indicate those channels are kind of a basic item that is held in place with pieces of 3M adhesive pads or something similar. I wouldn't go pulling those channels out to see what may be going on under them until you clean up and seal those gaskets with a bead of Green Grease and see if that fixes the problem. Here's the first thing that popped up when I searched that roof channel...

Deepsea21, those are just 'stick-on' strips that 'stick' on your existing trim. They do not replace the ones on the car. At the very least, that is what I read into that advertisement and its install instructions (https://truelineautomotive.com/pages...e-roof-molding). Just an FYI

DTMenace did a post on how to remove these strips in August 2013.
Lift the hatch and carefully pry up the strip from the rear, there is a rubber strip attached to the trim strip which is snapped into the groove. It slides under the windshield trim at the front.

 

Ahhh... I was under the impression they were kind of like aftermarket door protector strips with adhesive backing that could replace the stock strips in the channel if they were pulled. So, there goes that idea. I fear if he pries and pulls those strips up he's going to crack the new paint job on them. Think I'd keep that as a last resort if nothing else works.

I'm like 95% sure his leak is coming from around this gasket and where it meets the metal (BUT I COULD BE WRONG). I think this is what needs cleaned up and sealed all around... I think the OP said he lives in FL and if this is a FL car and has been exposed to a lot of sun those gaskets get REALLY hot under there and can expand and contract over and over and over again while drying out at the same time and cause a little gap to form. I'm going to check the ones on my car and do some preventative maintenance with some cleaning and application of Green Grease around them.

 

I will absolutely do that this weekend. I cleaned around the gaskets today just need to but Green Grease. It's worth a good shot and would be a cheap solution..

Not sure if related, but when driving over 40 mph I hear the wind whistle from the side where the leak is. I wonder if the gasket could cause that or if it in fact points towards those roof liners I had painted a while back. I just don't want to chance breaking those things.
i do in fact live in Florida and I don't have a garage so I park my car under tree twice a day to find shady spots in my parking lot lol. So removing anything can sometimes break easily if it got brittle from the sun.

 

Senior member wassup you a good dude👍🏽💯

 

So bad news here....the leak has not stopped. I used green grease and thought it took care of it but ultimately it doesn't come from the rubber seals.
I sat in tue trunk to locate the area of the leak while my dad sprayed water on that area...speaking of a tight spot when you are 6"3. Good thing I'm not claustrophobic.

It's really hard to locate where the water gets in. I still wasn't able to locate it 100% but it seems to start where I drew the yellow line from front to back and down the headliner. (Please see image).

At this point I don't know what the culprit is. Any tips? Maybe it is the metal trim along the roof? What is actually underneath that metal trim (see picture)? And could it leak in from that area?

When driving over 40 mph I hear a whistling noise. Does that mean maybe the window isn't sealed/aligned right? Could that be the issue?

Thanks for any advise.




Could it be this thing? We had them painted a while ago and maybe they didn't put it in correctly?

 

That would be my bet.

 

Which one? Window issue/not adjusted right or the metal strip along the roof?

 

My guess is the loose strip along the roof allowing water to penetrate the window seal. they may have even damaged the window seal removing it?

 

​​​​​It is a possibility. What's actually underneath that strip? Are there spots where water could get in?

Quick side question...I was going to do the "water in trunk" fix and punch through the rubber drain underneath the vehicle. Which one is it I'm working on? The one closer to the wheel or the one closer to the exhaust?
Thanks again!

 

So I did a little water test and here is a picture of the area of the leak. Water leaks right onto the bulkhead cover.
I posted the area where the headliner gets wet.

I'm still not sure what's causing this. Could it be the roof strips? Is my window misaligned? (I do hear wind noise over 40 mph) but not sure if related.

Might have to take this in to mechanic soon and hope that they know what to do.

 

You may have already looked into this but Is it possible that the DS rear window seal has failed?
there has to be an adhesive seal.

(I’m only guessing, mine is a roadster so as a consequence I don’t have that window.)

The other repair is to sell it and buy a none leaking XF


I hope you’re able to locate the leak soon and that it’s an inexpensive repair

 

In my post #3 you can see a groove that goes around the upper portion of the rubber conduit end, this groove has the trunk steel fit into it and is a pain to get seated. In your post #11 you can see this groove, so it is not obviously sealing the hole in the hatch steel.
This may or not be your problem, but you should not be able to see this groove. This part of the rubber conduit is more or less identical to the other end of the conduit which has a groove as well and should fit like a grommet, partially inside the hatch body just like the other end of the conduit.

 

​​​​​​I sealed around those "harnesses/plugs" with green grease. I climbed into the trunk yesterday and had my dad spray water on it. Since the beige plastic trim panels in the trunk are out I have a direct view on the opening where those electrical cords come out and it definitely did not drip out of there.
So I'm thinking it's not those areas.

So basically I sealed all around those guys here (picture is before I sealed):

I only sealed the part that connects to the body of the car, not the one that connects to the hatch of the vehicle but I doubt water could somehow drip out where it does if the hatch part was not tight.

 

Would hate to sell Love that car and made it mine over time with a few add-ons etc.
Really window seals look fine as far as I can tell. Man I hate leaks...so difficult to hunt down.

Wonder if I could take it to a safeglass auto store or any of those glass repair/replace facilities and they could figure out where it comes from and/or adjust the side window in hight and told cause I'm starting to feel like that might be the issue given that I also have wind noise so something isn't sealing right.
