2014 Ford Fiesta: transmission slipping

Filed Aug 5, 2025 · Transmission · OK

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.

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.

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.

We bought the car february, 2016. As we drove the car more, we began to notice shuttering and chattering. An ase certified mechanic test drove our car. He said it had a bad torque converter shutter that gets worse the more you drive the car. When in sport mode, when you shift from 1st, it skips 2nd, and goes straight to 3rd. There was loud clattering noise while driving. The transmission slipped when gearing down and trying to accelerate, especially uphill. March 1, 2016, the transmission was worked on at ramey ford, princeton, wv. May 31, 2016, the transmission was worked on at ramey ford, princeton, wv. May 9, 2017, the transmission was worked on at mountaineer automotive, beckley, wv. November 28, 2017, the transmission was worked on at mountaineer automotive, beckley, wv. March 3, 2020, I took the car to my mechanic at act auto, beckley, wv because the car had been making a whining sound that continued to get louder. I was told that the front pump of the transmission needed replaced. My wife and I are afraid to drive, for fear that the car will stall out or cause us to have an accident.

I have a 2014 ford fiesta with 88,000 miles on it and it has the faulty dps6 transmission that slips out of gear and shudders so bad under accelerating that it sometimes barely moves, this is a major safety issue and ford knows it! , I have taken my vehicle to ford to asses the transmission and they agreed that the transmission was faulty and needed to be repaired under the new extended warranty that they offer, the problem is my vehicle has a rebuilt title and they refuse to do the warranty work even though this is a serious problem and ford know it since they are in arbitration for it. Just because my vehicle has a rebuilt title doesn't mean that it should not get repaired under the warranty. This issue needs to be made a factory recall so they will have to fix it!

A heater vent is stuck and the timing belt is slipping over it as the car starts up. Sounds like an automatic gun going off. Happens every time I start the car. Occasionally happens when the car is moving and the sun comes out. Have tried turning to AC off and the fans off nothing helps.
