Have a 2013 convertible that leaking, typically in a heavy rain with car sitting for several hours, we get a couple quarts of water on the rear passenger floor. No signs of water anywhere except the carpet. Ford dealer has had the car more times than I care to admit, they've removed most of the interior(carpet, seats, interior panels) to try and find the leak. Adjusted the windows, resealed all the seams on the floor. Have opened a case with Ford, their engineer has been out, indicated the issue was a seam leaking in the top, Ford replaced the top last week and when it rained yesterday, it leaked. Love the car when it's not a swimming pool. Any thoughts would be appreciated.
