Ford has issued a dealer Technical Service Bulletin for a clutch issue on 2011 Mustangs built before April 25, 2010.
Affected models with less than 10,00 miles might experience a clutch pedal stayout condition, where the clutch will remain on the floor even after it's released during high RPM shifts, something that sounds like both an annoyance and a potential safety issue. According to the TSB, the repair takes less than an hour.
It is not clear if the clutch issue will eventually precipitate a recall, but there have been no rumblings from the National Highway Traffic Safety Administration to suggest that it will. Have a look at the details after the jump or speak to you're dealer if you're not sure if your pony car is covered.
