I have the same problem. I discovered this after a 2 week period of rain when the well where the spare is stored was flooded with water. I'm pretty sure there is a spot that is slightly indented that is letting water in between the seal and it's dripping down into the trunk.

I noticed the spot after I washed my car, saw a wet spot on the carpet and traced it back. It's also soaked/ruined the fiberboard used to cover the spare.

I'm taking the car in next week to get it looked at along with some other warranty work. The seal between my trunk and wing is also coming apart.

Add me to the list. Shortly after I got the strut mounts replace for the clunk issue I noticed the leak.

Did any one ever find a resolution?

Bring this back from the dead.... Both driver and passenger side in trunk is wet. We had alot of rain last night. I did replace my trunk with a sti trunk and I'm not too sure if I had this leaking problem before that. Possibly the trunk isnt latching tight enough?

Downpour then wet trunk (while parked). I went from winged wrx to wingless and I got water in my trunk. I waited until it was dark and had my wife hold a flashlight in through the pass through with the trunk closed and voila, light shining through near the rear windshield and trunk. I messed with the weather stripping a little and haven't had a problem since. I'm also careful to remove any debris that might get in between, i.e.- leaves, branches, etc...

Well I had this problem also and it turned out to be the black gaskets around the taillights. One was torn some how and the water was getting past it. The spare tire was FULL of water, and I pulled the plug out, wiped it out with a towel. I went to the dealership and they got a new gasket thing for me and no problems since. I would also check the weather stripping around the trunk and make sure it doesn't have a tear in it. On previous cars, i took silicone and smeared it on thick and smoothed it out on the tear and it didn't leak.

Bumping.......

I've been experiencing this for a while now, but it's finally come to a head because my car was smelling like butt cheeks. My driver side front and rear carpets were wet AND since Ive had the car the driver side trunk area always finds a way to accumulate a puddle.

Now I've figured out whats causing the carpet to get wet = the gutter just below the windshield needs replacing and Ill have the windshield resealed just to be safe.

Now the trunk is I soaked the hell out of the car with a hose. NO water inside whatsoever, so I'm assuming those flapper exhaust vents in the corners of the rear bumper are letting water in when I drive in wet weather There's also a tiny whole in the driver rear bumper corner I have to seal up but I sprayed water in through the wheel well and nothing came in.

Would it be problematic if I sealed that exhaust flapper on the right side, because I dont want my body starting to rot with a puddle of water in there?

In my 2006 WRX, I had a leak in my trunk because there was a missing rubber plug on the back of the trunk wall. The plug looked like the cone shaped rubber one in your 2nd picture in post 10.

There's no other holes like that cone plug that I see, so I still think it's coming in through that exhaust box flapper

no one knows if it's ok to close up that black exhaust box above to avoid water possibly coming in?

i to have had the unfortunate experience of water in my trunk. after testing and searching i have found that water is leaking in right next to the hinge on the drivers side of my trunk. i am including pictures below with the area in question circled. could this due to the fact that my rear windshield isnt sealed properly? the weather stripping around my trunk is fine. any help is appreciated...

Here are some general possibilities:

*Windshield sealant was never properly applied (this happened on my front windshield after a new one was installed)

*Body sealant was never properly applied

*Sunroof drain tubes are clogged

*Missing rubber plugs such as the "cone" type described above or flat plugs

*Tail lamp gaskets are made from neoprene and will over time disintegrate; you can order new gaskets (as described above) or use neoprene foam tape (this is what I did)

*Trunk opening gasket has dirt and debris stuck up underneath and/or the sealant that is in the inside of the gasket itself where it sits on the metal lip of the car has dried/inadequate and allows water in

*Trunk lid does not sit properly against gasket

*Weatherstripping is worn

*Debris has been caught under the outside roof to rear-glass weather-strip (as described above) and is allowing water to accumulate and spill through a seam or seal (e.g. windshield); possible solution: use compressed air to force debris out; use a non metal snake to push debris out

*Rear strut-top to body does not sit properly and/or the undercoating sealant in this area of the underside of the strut-tower is inadequate. Possible solution: remove rear strut(s); clean area with a soft bristle brush to remove dirt and other debris; cover opening with painter's tape from the inside; apply new undercoating and let dry; use butyl-caulking on flat-outer side of tophat where the studs are to create a positive seal between the tophat and the body of the car (this is what I did)

That black "vent" in the rear below the jack - DO NOT BLOCK OR SEAL THIS - it is there to allow fresh air to flow through the car from the dash-cowl, in and through the car and exit out the rear. They are also in place (both sides) as a means to depressurize the car when you close the doors or when the car has been sitting in the sun for a period of time.

*And check that your spoiler is screwed down tight. If not, might wanna add some silicone sealant before torquing back down.

from the guy above, my problem with a trunk leak was this

*Trunk opening gasket has dirt and debris stuck up underneath and/or the sealant that is in the inside of the gasket itself where it sits on the metal lip of the car has dried/inadequate and allows water in



And my remedy was going to subarugenuineparts.com (chapman subaru, bellevue wa) and ordering a new trunk gasket. it came in, i removed the old gasket which was worn after 10 years, and cleaned the channel all around. applied new gasket and bing!

how was your car parked (up- or down-hill, level ground) when the truck leak occurred?

I have this same problem and it seems to occur after I wash my car, always on the drivers side of my trunk. It's probably debris, but I'm glad that I'm not the only one having this problem!

There is a good sticky for this I think. I have it bookmarked on my work computer...will post link Monday.

3 problem areas:
1. main gasket around trunk which can leak in the corners
2. taillights
3. spoiler mounting points

for me it was taillights. Paint guy decided to remove the worthless looking piece of foam on the back of the left tail. guess what, its not so worthless.

I will try to get in truck with torch, or ask someone to torch trunk to body stick if I'll see light inside.

Big-E - great list. I spent the weekend tracking down my trunk leak. Turned out to be what was described above. Water was working its way under the gasket (which had completely expired adhesive and a bunch of gunk underneath) and into the trunk.

Instead of ordering a new gasket, I just re-used the old one. I cleaned both the gasket and the metal surface thoroughly and applied silicone sealant to the leading edge, because that's really the part of the gasket that needs to be sealed against water intrusion. I was concerned that if I used gasket adhesive, (1) the gasket would be harder to remove in the future, and (2) water would still get underneath the leading edge and sit there. Sealing the leading edge seems to have worked pretty well as per the hose test, but we'll see how it fares in the next heavy rainstorm.

One other thing I did was to adjust the latch (on the body side) down a bit, to pull the trunk tighter onto the gasket.
