NHTSA Complaint #11532490 — 2012 FORD FIESTA

The dual-clutch transmission on this 2012 Ford Fiesta has ceased to shift gears correctly once it heats up after driving briefly, and becomes unable to shift in reverse. The engine also seems to occasionally be overspeeding between gears. The transmission control module, though recalled, is functioning properly and has been determined to not be the source of the issue. A similar problem occurred approximately the week before this issue began when the transmission control module (TCM) began throwing faults. The TCM was reprogrammed and the car functioned normally for a week before the issue seemed to recur. When brought to the nearest dealership, they determined that the TCM was not the cause of the issue. The vehicle has well under 100k miles. The nearest dealership thought that shift fork B was frozen, which caused damage to the clutch. A second opinion from another mechanic said that this was a common problem with the 2012 Ford Fiesta. I contacted Ford Customer Care and was advised that the VIN of this vehicle was not included in the 2012 service update for these same issues. However, since it is displaying the issues addressed by that service update and is under 100k miles, it may need to be.
