2014 Ford Fiesta: sudden loss of power

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.

2014 Ford Fiesta manual sedan exhibiting recurring, dangerous hood latch malfunction (recently noticed) where hood unlatches while driving/parked & experiencing sudden power loss when AC is used (fuse removed to prevent this dangerous condition). Potential safety hazards: obstructed vision, hood detachment, engine tampering, sudden loss of control. Ford Service Advisor admitted hood latch "should" be a recall, yet dealership attempts to charge $350-$500 ($250 diagnostic) for repair instead of initiating recall. This raises concerns Ford prioritizes profit over safety, esp. since Fiesta is discontinued. Other issues include previous brake pad lock-up requiring costly ABS Hydraulic Control Unit repair & door latch recall 20S15 ("door may unlatch while driving"). Multiple recurring issues suggest vehicle may be a lemon overall. Request immediate the federal safety agency investigation into hood latch defect & electrical/AC power loss issue. Urge recall consideration. I will gladly allow my vehicle to be studied in a the federal safety agency lab to aid investigation. Concern heightened by Ford's discontinuation of model.

Due to the poor design of the dsp6 transmission, I have almost been in quite a few accidents when pulling into traffic on a city street and the transmission shutters and shakes so badly that I lose power and have almost been hit. Ford needs to be honest and upfront with the hardworking people that shelled out good money and repair the problem!

Car currently has 90k mi and the clutch is bad $1700 for dealer to replace. Ford extended warranty to 150k mi on transmission control module which is inside the transmission. The dealer replaced the module at no cost and then the module starting leaking transmission fluid and as a result there was a roaring noise from one of the bearings which is inside the transmission. Ford and the dealership refuses to accept responsibility for this. The worn clutch and transmission malfunctions is a know issue on these vehicles. While driving the car loss acceleration and it jerks when taking off and loss of power and the AC doesn't blow out cold air. Stay away from ford

Cooling system fails on the car without warning. The temperature gauge and over temperature warning light do not indicate / come on until the engine fails and the vehicle looses power. I have had to replace the engine two times. Each time there was no indication of low coolant or overheating condition. My car was at highway speed and lost power and shut off within seconds leaving no time to safely pull off the road. Both times I was on a state highway with little to no berm.

1.0 liter ecoboost engine will overheat without warning and catostophic engine failure will result. The coolant temperature and warning lights do not provide any early warning. The engine looses power / fails and only then do the warning lights come on. I was driving up a hill and the car lost power. I downshifted and noted no warning lights or out of normal ranges. I was attempting to pull off the road and the engine lost all power and left me sit in the middle of the road. Only when the engine stalled did the coolant temperature light come on. The gauges provided no early warning of a cooling issue. This is the second new engine I had to have ford install in this car and both times the exact same thing happened. Cooling issue with no warning prior to catastrophic engine failure. Both incidents left me sit in the road with no way to pull over. I had no warning. This is to report the latest incident.
