I have owned my car for two weeks now and I have had constant mist in the lower half of my rear windscreen, it is'nt the full screen-just blotches of mist. I have tryed wiping the glass on both sides but it seems as if it is inbetween the glass! Does anyone know if it is two pieces of glass together? Anyone else had the same problem? I think i am going to take it into the dealer and get them to take a look under warranty.
