2014 Ford Fiesta Powertrain & Transmission Problems

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 contact owns a 2014 Ford Fiesta. The contact stated that while his wife was driving at an undisclosed speed, the vehicle jerked, and an abnormal sound was coming from the engine. Several unknown warning lights were illuminated, and unknown messages were displayed. The contact's wife continued driving at slower speeds. The vehicle was towed to an independent mechanic who diagnosed that the transmission control module (TCM) and engine control module (ECM) had failed and needed to be replaced. The vehicle was not repaired. The vehicle was towed to the dealer; however, the vehicle was not diagnosed or repaired due to the cost. The manufacturer was not notified of the failure. The failure mileage was approximately 69,000.

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.

The car had poor acceleration and limited power and it was difficult to pass and keep up with other road traffic. Dealer estimate $4400 for clutch repair internal to transmission.

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.
