i too have the leaky spoiler.. i can handle it in the spring/summer/fall.. as the water eventually drains back out.. but in the winter up here, the spoiler is just a tank of frozen water(ice).. so it's like having an extra 30lbs sitting on my trunk lid

Water is in back spoiler. You can hear it moving everytime you open the trunk. Not worth getting fixed because its not really causing problems, it's just annoying.

I have water build up in the spoiler. This is the 5th or 6th water leak in this vehicle. I was just wondering if there are others out there with the same problem. It should also be noted that the trunk has been re-painted by the dealer twice because the spoiler was chipping the paint.
