Clutch shudder on light acceleration (2011–2016)
Ford's program 14M01 says some 2011–2014 Fiesta and Focus cars built before June 6, 2013 may show excessive clutch shudder during light acceleration, which may be caused by fluid contaminating the clutch from leaking input shaft seals. Ford says cars built from June 6, 2013 have improved seals, but its later program 19N08 says 2014–2015 Fiesta and 2014–2016 Focus cars built from July 9, 2013 were made with clutches that may judder or shudder on light acceleration from a stop or during shifts; the repair uses revised clutch material.[2][3]
Reported symptoms
- Shudder or judder when accelerating gently from a stop
- Shudder during shift events
- Transmission fluid leaking from the clutch housing (on cars with leaking input shaft seals)
