Hello to forum,
My boot is leaking water as you can see on the pic (GTS ‘11). It’s leaking at the bottom side of the big “pillow” that seats let’s say behind the bumper between the exhaust pipes(I hope pic makes more sense). Any ideas? The “pillow” is glued and I wanted to check before to remove and investigate further.
Thanks in advance

I have added one more pic to make it easier. I have removed only the covers from inside the boot.

I have checked those but I haven’t seen the water to get inside the boot. Looks pretty dry. The water must stuck somewhere and gets inside the boot from the area I have add the kitchen roll.

unfortunately I think its a common gran turismo issue .water flows down the rear window/trunk drip rails and through the inside of the rear bumper (next time you wash your car if its working correctly you'll see two puddles directly in the middle underneath the car. If theres too much water going down at the same time / perfect angle (a rain storm as the perfect example) the water wont go straight down those channels and instead starts to pool in the area directly under that cushion in your picture because the actual interior trunk is plastic bolted on to the rear steel car and isnt sealed with a gasket or atleast the gasket isnt great... as soon as you take off that cushion theres 3 /4 torx bolts that I imagine are rusty since thats where the water is coming in from. (a bunch of us here have the same issue and mine is a 2015 so you woulda thought they fixed this simple defect...)

I have seen those torx bolts and you are correct. Are a bit rusty. Do you think the water comes in from the bolts? In that case I can use a sealing o-ring or something like that? Or I need to unscrew the whole thing and put something like a gasket underneath (if the water comes in between the 2 parts)

Yes it's absolutely coming in from the plastic trunk not sealing with the rear steel of the back of the trunk (can't tell you if its due to flexing of the materials/ no gasket between the two or the Torx bolts loosen over time and cause the no seal ) when you take off that padding you have in your picture that's where the water starts pooling and then if there's too much water or you drive around / at angles then it will eventually make its way to the bottom of the trunk since that's the lowest part there's multiple other members who have commented or documented not taken off that trunkliner ever or not replaced battery in years and then when they finally do they see that antenna/motor sitting in the plastic trunk is all rusted out too.

You are correct. I removed the cushion and the water comes in the trunk from there. The question is why the water gets blocked underneath the torx bolts. Even If somehow we seal the two pieces then, I could assume that the water will still be blocked somewhere else in a different area of the car. How we can make sure the water will go down to the floor.
