2014 Ford Fiesta electrical system problems

“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 NHTSA investigation into hood latch defect & electrical/AC power loss issue. Urge recall consideration. I will gladly allow my vehicle to be studied in a NHTSA lab to aid investigation. Concern heightened by Ford's discontinuation of model.”

“The back passenger back door had problems wouldn’t close rt now can’t open. In May it felt like it wasn’t getting power, engine light said turn off car for 10 minutes, while stuck in traffic, so i had it towed to Upland Ford Dealers, they charged me $209.99 Just to look at it! Then after inspecting it they wanted almost $4,000. Which i can’t afford. They said it was the Clutch Assembly part. The car also has some electrical problems like the car stopped showing the millage last was a round 101. The phone not connecting & the charger plug not working either”

“My car just died on me. No warning or anything. Took the dealership 2 and half weeks to fix my car. They came to the conclusion that it was my Trans harness cable. Cost $820.00 to fix.”

“My 2014 Ford Fiesta started to "Smoke". There was a smoldering Electrical short emitting smoke from fusebox. The car would not Start after this incident. I have a letter from Ford indicating the Fusebox had a recall on this Issue due to a corrosion defect. I took it to local Ford dealer who Confirmed recall/defect”
