well. 8 1/2 months after my CSC failed the first time on my 09... I felt my first loss of pressure in the pedal. It went about 1/3 of the way down with no pressure before engaging. So I can tell the replacement CSC/MC are beginning to have the same issue again.
At about 33,000 miles now on my 09. It's a little over 4.5 years into service.
