there was an brake light seal issue in centre above rear window way back in my early years of eriba ownership., but not heard of window seals leaking till the recall,
but sadly Julie has suffered with one, as mentioned above.
your eriba is fairly new, so would suggest its an annoying re fit of a new seal, from the recall at fault, (human element possible muscle fatigue) get them to hose the eriba while your in there to check their work
fingers are crossed for you to have no more issues, but more happy holidays.
