Service Bulletin Issued for 2011 Ford Mustangs with Manual Transmissions

If there's one time you'd really like your clutch to work right, it's when you're hammering the car and making redline shifts. If you own an early-build 2011 Ford Mustang, though, this could be a problem.

The Problem: This is not a recall, mind you, just a drivability issue Ford would like to take care of. If your Mustang was built on or before April 25, 2010 and has less than 10,000 miles on it, you may be affected by what Ford is calling a "clutch pedal stayout condition." The problem occurs when shifting at high rpm -- also known as driving the car the way you're supposed to. When doing so, the clutch pedal may stay on the floor when you take your foot off of it. As the rpm comes down, the clutch will re-engage by itself, often abruptly. Ford doesn't consider it a safety issue as it only occurs when shifting at or beyond redline and it corrects itself, if in a rather uncivilized manner. The problem affects both V-6 and V-8 Mustangs with manual transmissions.

The Fix: Ford says the problem is in the clutch assembly itself. High RPMs create centrifugal forces on the clutch assembly that are apparently strong enough to overpower the diaphragm fingers on the clutch that push back against the release bearing (also called the throw-out bearing). As engine RPMs come down, the centrifugal forces decrease and the fingers push back on the release bearing like they're supposed to. Ford's solution? Swap out the brake pedal and bracket assembly inside the car. There's no explanation in the TSB as to how this would help, but it apparently fixes the problem. We'd guess that the new assembly contains a stronger return spring on the clutch pedal that will pull the pedal back and the release bearing along with it. It doesn't appear to address the actual problem, but the TSB also stipulates 0.8 hours of labor, which is a lot less than it would take to drop the transmission and replace the clutch. The fix should be covered by your warranty. Ask about TSB 10-19-4 the next time you're at your local Ford dealer.

Number of Vehicles Potentially Affected: Unknown, but likely several thousand.
