[nono]My 2012 Focus has the same issue with idle speed trans shudder. The same resopnce from the dealer was a "brake in" issue. The car has 5000 miles on it and it still shudders. I called customer service and the woman informed me that I would have to pay for a transmission evaluation out of my pocket, so the extended warenntee did not help. Un believeable... A new car should not shudder like this period. The dealer will not take this car back, I am taking it in to another dealer next week, I might be trading this thing in.
