So yesterday I went to put something on my back floor and found the carpet to be soaked with water. i opedned the trunk and found water in the spare tire hole. This never happened when I first bought the car in September and Im wondering if this could have happened because of my carbon fiber tailights. I might get some caulking once everything dries and fill in where the tailights meet the body in the trunk, if thats the best course of action. Anyone else have this problem???

 

There is a thread exactly like this less than a week old. Search back a couple pages, there were some useful replies.

 

Most of the time the some aftermarket Tail Lights don't come with a great gasket. When I put my new tails in I took a water hose and sprayed over it lightly to see if I had any leaks. You may want to try that to pin point where it is comming from.

 

Bingo.
