It just finished raining in my area. I went outside to look at my car after the rain and found some moisture inside the back window!!! At first I just thought I forgot to close one of the windows tight so I went in the car to check. Indeed all the windows were tightly closed. It seems the back window seal is open? Well going to bring my car in for warranty work tomorrow. I don't even have tint on my window so this shouldnt have happened. This really sucks!!

Was curious if any other IS has had this problem. It just blows my mind that it happened to a 40k car.

I attached an image.

 

Are you sure it was the rain water but not the hot interio temp causing condensation?

If not, bring it to the dealer and ask them to set up a test with pressurized water. Watch out.. if they don't find the leak, they will charge you!
