I'll be getting my Aviator back tomorrow that was in for water leaks also. 2nd row carpet was a bit wet and there was almost 2 inches of water in the spare tire well. There was a TSB for the rear leak which was addressed, and it took them a while to find the front leak which they told me at first was weather stripping. They say now it is fixed and it seems to be the drain lines. I'll know more tomorrow when they deliver the vehicle to me. Mine was a July 20 build. How is it they are still having these issues?
When I wanted the Aviator back when they said they were waiting on weather stripping I told them I needed to pick it up as I was headed on a trip and was not supposed to put that many miles on the loaner (supplied by Enterprise). Told me my trip would be OK, and besides my vehicle interior was all apart. I assume that included the headliner. Not to worried about them returning it to normal. My other car is a Mercedes and last year had to have the headliner replaced under warranty because it was sagging. Looks perfect.
