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.
