2014 Ford Fiesta Powertrain (other) Problems

Brand new OEM ford clutch slave cylinder failed while in traffic. Part number DG9Z-7A564-B fell apart during test drive after it was newly installed. Lost ability to use the clutch pedal and could not pull the car out of gear while in traffic. Component was not inspected by manufacturer yet, there were no warning lights on the dash when it occurred. Was able to get the car back home and noticed brake fluid pouring out from inside the bell housing of the transmission where the slave cylinder is housed.

Transmission was supposedly rebuilt back July 26, 3021. Now transmission has had a new dual clutch replaced but other concerns are still there jerkiness on accelerations. In 2021 the transmission was not fully rebuild as per recall. Only clutch assembly was done and not the back end. Which now could be the problem. Second, colonial Ford sated transmission rebuilt has lifetime warranty which a lie. Colonial Ford doesn’t offer lifetime. The service advisors lie about this all the time. Now the car jerks on acceleration after clutch replacement. Dealer and Ford still take no responsibility over the product! The car has 145,000 miles still under the 150,000 mile warranty isssue by you!

I’m reporting a failure with the Transmission Control Module (TCM) in my 2014 Ford Fiesta. The vehicle has exhibited consistent issues tied to the known PowerShift DPS6 transmission defect: including gear slipping, delayed acceleration, hesitation, and sudden loss of power while driving—particularly dangerous during intersections or merging situations. Ford previously issued Customer Satisfaction Program 14M02 to address this issue, but I was told my VIN is no longer eligible due to build date. I also requested coverage under Ford’s one-time TCM replacement extension announced in 2023, which was meant to support customers outside the 10-year window through June 30, 2025—but I was denied this assistance as well. I’ve opened a formal case with Ford Customer Relationship Center under reference number CXH05170436-N7Z6Z1, after being denied support for a documented transmission control module failure. These symptoms present a clear safety risk, and the refusal to support a documented transmission failure—even under goodwill— I hope this will be reconsidered for safety investigation.

Vehicle presented to A&T Auto Repair with rotation-dependent clunking sound. This clunking started after loud metallic snapping noise occurred while coasting in gear on a flat surface. Mechanic noted that clunking noise came from the transaxle. Once the transmission fluid was drained, metallic grit and large chunks resembling gear teeth were found in fluid. A replacement transaxle was installed, along with a new "clutch kit" containing flywheel, pressure plate, and slave cylinder. Following installation and engine start up, slave cylinder leaked, prompting the order of new parts and replacement labor. According to Mechanic, four different slave cylinders from two separate manufacturers leaked in the same fashion upon engine startup, due to a "locking" malfunction of the slave cylinder. The recurrent nature of the parts failure seems to indicate a deficiency in part design that causes a fluid leak, possibly endangering driver and passengers in the event of a transmission failure.

The vehicle has experienced ongoing failures with the DPS6 PowerShift transmission system. Symptoms included slipping between gears, failure to engage 6th gear, jerky shifting, and bucking during acceleration. A transmission warning light appeared multiple times. These issues occurred daily and worsened over time. Eventually, the vehicle became unsafe to drive—it would over-rev, buck violently, and lose power during traffic conditions. A retired Ford Senior Master Technician confirmed the issue is consistent with a faulty Transmission Control Module (TCM), which is covered under Ford’s Customer Satisfaction Program (CSP) 14M02. Despite this, the dealership refused to replace the TCM. Instead, they replaced a speed sensor and returned it to me. The vehicle broke down again within minutes and had to be returned. The dealership has now suggested dropping the transmission for further inspection at a cost of $2,500, rather than honoring CSP 14M02. They also encouraged me to trade in the vehicle instead of repairing it. The TCM failure has not been resolved, and the vehicle remains unsafe to drive.

This car has a standard transmission and a hydraulic clutch. The synchronizer for low gear lets it pop back out of gear. This is extremely dangerous if you are pulling out into a busy lane of traffic. It throws the shift lever back out of gear with a lot of force. I have had the hydraulics bled but plan to take it to a dealer soon. There are others listed on YouTube as having the same problem.

I was driving on the highway on October 3 and suddenly my vehicle stalled on me. When I pressed the gas pedal, the vehicle no longer moved. I had the vehicle towed to my house and had a mechanic do a diagnostics. The mechanics thinks the issue could be the computer or the transmission not communicating with the computer. The vehicle can no longer shift gear and it can not crank as well. It is very dangerous for a vehicle to stall in the middle of highway like this. The 18 wheeler behind me barely missed me and it could have been a fatality if I was hit in the rear. Thanks god I managed to pull to the center median and had a friend come help towe the vehicle to my house.

MY 2014 FORD FIESTA HAS A MANUEL CLUTCH THAT HAS MALFUNCTIONED SINCE I PURCHASED THE CAR NEW IN SEPTEMBER, 2013. THE PROBLEM BEGAN WHEN THERE WAS APPROXIMATELY 20,000 MILES ON THE VEHICLE. THE CAR WOULD SOMETIMES STALL OUT AND OTHER TIMES IT WOULD NOT PROPERLY GO INTO GEAR. I WOULD HAVE TO SHUT DOWN THE ENGINE TO GET IT INTO GEAR. I CALLED THE FORD DEALERSHIP AND THEY INFORMED ME TO BRING THE VEHICLE INTO THE DEALERSHIP. THEY SAID THEY FOUND NOTHING WRONG. THE CLUTCH HAS CONTINUED TO MALFUNCTION OCCASIONALLY UP UNTIL THE LAST 6 MONTHS. NOW IT HAS BECOME DANGEROUS. THE CAR WILL NOT GO INTO GEAR PROPERLY MOST OF THE TIME. WHILE RUNNING, THE CLUTCH WILL KEEP PULLING EVEN THOUGH IT IS PUSHED ALL THE WAY DOWN TO THE FLOOR OF THE CAR. I WAS IN A LINE OF TRAFFIC AND ALMOST HIT THE VEHICLE IN FRONT OF ME BECAUSE IT KEPT PULLING. I HAD TO SHUT THE CAR OFF AND RESTART IT TO STOP THE PULLING. THERE ARE NO WARNINGS OF ANY KIND PRIOR TO THE FAILURE OR DURING THE FAILURE. THIS IS PUTTING MY LIFE AND OTHERS AT RISK. I ONLY HAVE 94,000 MILES ON IT AND IT IS TOO DANGEROUS TO CONTINUE TO DRIVE. THERE SHOULD HAVE BEEN A RECALL ON THIS PROBLEM BY FORD. IT IS AVAILABLE FOR INSPECTION. I HAVE NOT HAD IT REPAIRED AS OF NOW.

At the time of this complaint, the Ford Fiesta that's the subject of this complaint has received 1 whole new transmission and 1 TCM replacement within 2.5 years. The first two times there were warning lights, but now no warnings are showing. To put this issue into perspective, I have only owned this car for 2.5 years, and it was purchased from a dealership used (however the dealership never mentioned the rampant transmission issues or informed me of the recent lawsuits about the Ford Fiesta). The replacement of the TCM was completed on September 16, 2021. This repair took a month to complete. Now, after being repaired for a mere 2 months, the car is exhibiting the exact same behaviors as both previous occurrences. Both previous repairs were completed by professionals, and should have fixed the issue. However, the transmission issues continue to reoccur. At this point, the car has become a major safety concern. The transmission issues are becoming extremely frequent after the "repairs" and "replacements", and are sudden in occurrence while driving. There is no warning the gear will slip into what seems to be "neutral", or that it will fail to accelerate. Additionally, the car will randomly fail to respond to gas pedal presses, especially at intersections or on hills. I fear that this car is dangerous to drive, as the issues are so sudden in nature. I have tried to settle the issue with Ford directly, but they have ignored me every step of the way. At one point, they said they would try to start a buy-back process, but then refused to return my follow-up calls.

The DSP6 transmission is slipping out of gear and into neutral. This causes the car's momentum to fall below safe advised speeds on highways, and also can cause the car to jerk suddenly at intersections. Ford knows about this issue but is refusing to repair it.
