Just like to known if this is a fault or how things should be. Had my cx5 for a few weeks now and must say am loving it (much better than Vauxhall mokka I had), anyway I was cleaning car yesterday and front windows were open about 1/4 when i started to clean them (so I could clean top of glass), as I cleaned them the glass move about 1/2 inch like it was moving out of there runners, is this normal?
