I've driven at least 10 2012 focus most rentals and this is my 2nd 2012. They all had the same behavior. After long drives the clutch noise (grinding noise) will show up. After long periods riding the clutch some shutter appers and will go away after the clutch cools down.
Even the 50000km rental Had exactly the same behaviour .
Its a great car way better than any cruze or dart. All the owners should enjoy all the pros instead of keep making a huge deal of the cons. I'm a very happy focus owner and all you guys should be as well because we have a great car.
