I have had my Focus for a month or so & love it but (there is allways a but) I am fed up with the creaking doors so it is due to go in to Ford on Tuesday (29 July). I know this is an issue reported elsewhere so I am not asking about that. However, the rear window wiper is less than useless & just smears the window. Is this a design fault or should I mention it on Tuesday as the car is still under warranty? Can it be adjusted or do I just have to accept it?
