2014 Ford Fiesta vehicle speed control problems

“I own a 2014 Ford Fiesta. On June 23, 2025, I brought my car to McCarthy Ford in Chicago due to a check engine light and other concerns. I told them I didn’t know what was wrong and paid for a diagnosis on my car. They fixed the hood and only mentioned the issue with my catalytic converter, which I could not afford to repair at the time. However, they never mentioned or inspected the Transmission Control Module (TCM) even though my car was eligible for extended coverage under Customer Satisfaction Program 14M02, which expired a week later on June 30th, 2025. Shortly after that visit, I relocated to Phoenix, AZ, and the vehicle began showing clear TCM failure symptoms: loss of acceleration, inability to reverse, and the wrench warning light. Ford corporate told me only the original servicing dealership could escalate the case for goodwill repair, but despite multiple attempts to contact them, I have received no response. While the converter was noted, that is an emissions issue. My current problem is a known, unrelated transmission defect that has now left my car unsafe to drive. The failure occurred just days after the TCM warranty expired, and Ford’s system…”

“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.”

“I am writing to request Autofair Ford of Haverhill immediately repurchase the 2014 Ford Fiesta Titanium I purchased from them in 2019. I am requesting to be refunded the full purchase price plus all additional costs for registration, warranties and expenses associated with the 2014 Ford Fiesta Titanium that was sold to me. This vehicle, has since August 2022, been at Jannell Ford in Hanover Massachusetts, with a transmission defect that is unable to be repaired. As you will see from the enclosed documentation Ford apparently knew the transmission was defective and prone to serious safety concerns when they sold the cars originally and resold them through their dealerships. Additionally, Ford has allegedly (per news articles in the Detroit Free Press) instructed its dealerships to stall and delay resolving issues with the customers who purchased Fiestas and Focuses. My experience with Jannell Ford of Hanover and Autofair Ford of Haverhill can only be categorized as a concerted effort to delay and stall, by the dealerships not returning phone calls, not doing what they said they would, not providing information when asked repeatedly and most especially by not…”

“CAR JERKS AND WHEN I UNLOCK DOOR ONLY 1 DOOR UNLOCKS AND THAT IS DRIVER'S SIDE TRANSMISSION GOING OUT AND EVERY TIME I PUT GAS ACT LIKE DOES WANT TO START UP AGAIN AND THEN ITS TAKES FOREVER JUST TO CATCH UP SPEED”

“TL* THE CONTACT OWNS A 2014 FORD FIESTA. WHILE DRIVING 35-40 MPH, THE CONTACT FELT A LOT OF PLAY IN THE WHEELS AND THE VEHICLE JERKED. THE VEHICLE SELF CORRECTED AND OPERATED AS DESIGNED. IN ADDITION, THE TRACTION CONTROL, ABS, TPMS, AND MAINTENANCE WARNING INDICATORS WERE ILLUMINATED AND THE SPEEDOMETER WAS INOPERABLE. THE VEHICLE WAS TAKEN TO PRECISION FORD (945 N MAIN ST, LILLINGTON, NC 27546, 910-814 2243), BUT WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS CONTACTED AND REFERRED THE CONTACT TO A LOCAL DEALER. THE FAILURE MILEAGE WAS 100,000.”

“I HAD A RECALL I HAD MY CAR TAKEN TO DEALERSHIP IN ELDORADO ARKANSAS THEY CHARGE ME $440 AND REPLACED A COOLING FAN THAT I HAD NO PROBLEMS WITH MY CAR GETTING HOT. A FEW WEEKS LATER I HAD RECALL TCM AND LATER CLUTCH SHUDDER, AFTER THE LAST RECALL MY CAR STILL HAVING SLOW ACCELERATION, IT HESITATES EVEN WORSE”
