Another place this could be leaking is the boot and then the water would run down into your rear footwell.
I asked about this and two different dealerships have told me that they can leak on the rear hinges. I dont know how but they must know its a main issue.
I was also told that this can take hours to find. Why should owners pay for a problem like this. disgusting. How can an owner expect to pay for a flaw in the prodution process.
The rear clips that the tailgate lights screw into are rubbish too. (sponge washers under clips) How this is supposed to hold back water, and its in a low recessed trough, asking water." Come this way in its easy". LOL
if enough complaints go in, then Ford would have to do something. Look how bad it looks for Toyota at the moment.

Anyone else had this issue?
May be a good thing to get a list of owners/members with the same issue.
