Seen a big water spot on my driveway under rear of car today so i decided to investigate, after pulling out trim and carpet there was 3 inches of water in the spare tire compartment. Also the back passenger seat was wet. After looking i noticed the strut mounting area had rust around it and the drivers side still looks new but neither side carpet was wet at all . Any 1 else have this problem? Any help would be appreciated.

The best way to diagnose it is going to be to take a hose and run it over the trunk while you or someone is in the trunk with a flashlight looking for where it comes in. Then you can figure out how to fix it.

Sunroof.

If you search this section, several members (myself inclued) have talked to this issue.

Could be the third brake light CHMSL under the rear spoiler.
That's where mine was leaking.

Here is the picture:

See how the red lens isn't properly inserted from the factory.
The top seal is exposed on the upper-left and bent at the bottom
(which you can't see from this angle).
Some moron at the factory stuck it in crooked. You just
remove it and put it back in properly. Hope you find your leak.

Ok I found the leaks! The sunroof sags on the rear driver side corner , ran hose and pulled headliner down enough and seen the water coming in. And the leak in the trunk is coming in from under the seal at the back near trunk latch. I have an idea on how to fix the trunk but how do I adjust the sun roof ? Any help would be appreciated

Fixed!

Cool, mine leaked on the passenger front. Found it to be a hairline fracture of the plastic frame.
