My daughter has a C4 Picasso 2014 model, the opening window seals are coming loose making the inside mist up over night. These are the seals that the window slides inside and also some of the upper door seals are coming unstuck. Has anyone else had this problem and if they did, what was done about it from Citroen? She has only had the car for a couple of months and was told by the Citroen garage that this would probably be covered and they would carry out the repair but since then Cintroen have said NO! Thanks.
