My car does have the 12b37 update (got recalled) and the car has roughly 2500 miles on it. Bought in Apr 12. (I know low mileage.) When I pulled into my driveway when I first got the car home, I heard the noise. I said to my father that we should bring it back but then I told myself it was the clutches probably wearing in.
But that's what I was going to do was bring the mechanic on a test drive to show him the noise.
And I didn't really mean every focus, I was just mad at the time. And what I want to know is, if the noise is "normal",THEN what makes the noise AND why? But by the way you're (dan50) describing the oil leak with the clutch, it's not normal.
