The other morning after it rained all night, I opened my trunk to find a puddle. Anyone else have this issue???

 

Do you have an aftermarket spoiler?

Nope. I don't even have a spoiler.

 

Must be a defective or dislodged rubber seal if it leaked while just sitting there. Dealer will replace.
Shouldn't be hard to track down the leak by checking for water droplets.
After you're done, make sure all the water is soaked up from the floor (under the spare).

That was my first and only serious problem with my 03 AT coupe.
It came from the passenger side, getting in about half way between the front and back opening of the trunk along the upper side. There is a seam of interior trim up there.

The dealer had it twice, said they never found a problem, and it never happened after that. I suspect they fixed whatever it was and just didn't want to admit to there being a problem. The dealer, Cerritos Infiniti, was, at the time, staffed by the shadiest crooks this side of a Cal Worthington. Happy to say that since then, they cleaned house and they have provided me top notch service.

 

I had the same problem after a heavy rain. Had a water bottle in the trunk so not sure if it leaked. I'll continue to evaluate the situation and keep posting.

 

Sorry to bring up an old thread, but I just got an 06 MT sedan; and I have a leak in the trunk. It appears to be coming from around the passenger side tail light. I'm going to contact the dealership and see what they say. I'm glad to know this seems to be a somewhat common issue.

 

ROFL... joker...we still waiting on your water bottle investigation. its only been 5 years..
