What is the 2013-2019 Ford Fiesta Wet Belt (Belt-in-Oil) Timing Belt Degradation Clogging Oil Pump Pickup?

The 1.0L EcoBoost uses a 'wet' timing belt that runs submerged in engine oil.

Shed fragments migrate through the sump and clog the oil pump pickup screen… Repairs typically run $600-$8,000. Severity: high.

What is the 2011-2019 Ford Fiesta Electric Power Steering (EPS) Assist Fault — Sudden Loss of Assist?

Ford issued NHTSA recall 15V005000 covering certain 2014-2015 Fiesta (and related Fusion/MKZ) vehicles bui… Repairs typically run $0-$900. Severity: high.

What is the 2012-2017 Ford Fiesta 1.0L EcoBoost Degas Hose Coolant Loss & "EcoBoom" Overheating Engine Failure?

The 1.0L EcoBoost uses a brittle nylon degas/coolant return hose running from the top of the expansion tank to the engine. Over thousands of heat cycles the nylon becomes brittle and cracks or snaps, often at highway speed. Because the engine has a very small coolant capacity and… Repairs typically run $200-$4,500. Severity: high.

What is the 2011-2019 Ford Fiesta Thermostat Housing Coolant Leak?

The plastic thermostat housing on the 1.6L engine develops cracks and leaks coolant. The plastic becomes brittle from heat cycling over time. This can lead to overheating if coolant loss goes unnoticed. Repairs typically run $150-$400. Severity: medium.

What is the 2008-2019 Ford Fiesta Coil Spring Fracture — Snapped Suspension Spring?

The suspension coil springs fracture, typically near the bottom coil, often triggered by corrosion at the spring seat combined with road-input stress from speed bumps and rough surfaces.

What is the 2011-2019 Ford Fiesta Manual Transmission Clutch Judder & Slave/Release Cylinder Failure?

Manual-transmission Fiestas (5-speed B5/IB5) commonly develop clutch judder, a soft/sinking pedal, and inability to select gears when the concentric slave/release cylinder or clutch master cylinder fails. Owners report the clutch going to the floor when stopped and gears becoming… Repairs typically run $600-$1,400. Severity: medium.

What is the 2011-2019 Ford Fiesta TDCi Diesel DPF Blockage & Failed Regeneration (Short-Trip Use)?

Diesel Fiestas frequently suffer diesel particulate filter (DPF) blockage and incomplete/failed regeneration, especially on cars used mainly for short, low-speed journeys that never reach regeneration temperature. Soot accumulates, the DPF warning light appears, and the car may e… Repairs typically run $400-$2,500. Severity: medium.

What is the 2011-2019 Ford Fiesta Water Leak Into Footwell — Blocked Scuttle Drain / Pollen-Filter Housing?

Fiestas commonly get wet passenger (and sometimes driver) footwell carpets from rainwater entering via the scuttle panel at the base of the windscreen. Leaves and debris block the scuttle drain, or the scuttle-to-windscreen seal fails, letting water pool and overflow into the cab… Repairs typically run $80-$500. Severity: medium.

What is the 2014-2019 Ford Fiesta 1.6L EcoBoost Intake-Valve Carbon Buildup (Direct Injection)?

Like other direct-injection engines, the Fiesta ST's 1.6L EcoBoost has no fuel washing over the back of the intake valves, so oil vapor from the PCV system bakes into carbon deposits on the valves and ports over time. Owner tear-down 'case reports' confirm measurable buildup that… Repairs typically run $400-$800. Severity: medium.

What is the 2011-2019 Ford Fiesta Blend Door Actuator Failure — Stuck on Heat or Cold?

The Ford Fiesta is prone to blend door actuator failure, which controls the mix of hot and cold air in the HVAC system. When the actuator motor or its plastic gears fail, the system gets stuck blowing only hot air or only cold air regardless of temperature settings. A characteris… Repairs typically run $30-$400. Severity: low.

What is the 2011-2019 Ford Fiesta EVAP Canister Purge Valve Failure?

The EVAP canister purge valve sticks open, causing difficulty fueling (pump nozzle keeps clicking off), rough idle, and check engine light. Very common on the 1.6L engine. Repairs typically run $30-$150. Severity: low.

What is the 2008-2019 Ford Fiesta Power Window Regulator / Cable Failure — Glass Drops Into Door?

The plastic-geared window motor cog and the regulator's lift cables/clips wear or break, causing the window to fall inside the door, stick partway, or move only after repeated button presses. A characteristic symptom is a clicking/chattering or grinding noise as the glass jams or… Repairs typically run $150-$450. Severity: low.

What is the 2011-2019 Ford Fiesta SYNC / APIM Infotainment Freezing, Rebooting & Bluetooth/CarPlay Dropouts?

Fiesta SYNC/MyFord Touch and SYNC 3 systems commonly freeze, randomly reboot, drop Bluetooth pairing, and lose Apple CarPlay connectivity. Many failures are software 'handshake' hangs, but a subset are hardware failures of the Accessory Protocol Interface Module (APIM), which can… Repairs typically run $0-$1,200. Severity: low.

What is the 2011-2019 Ford Fiesta Rear Suspension Knock — Worn Rear Shock Top Mounts & Damper Bushings?

Fiestas (2008–2019, including ST) frequently develop knocking, clunking, or scrubbing noises from the rear suspension over bumps. Common causes are worn rear shock-absorber top mounts, deteriorated damper eye/lower-mount bushings, and torn rubber that lets the shock move in its m… Repairs typically run $300-$900. Severity: low.

What is the 2014-2019 Ford Fiesta Fiesta ST Rear Motor Mount (Dogbone) Bushing Failure — Vibration & Wheel Hop?

The Fiesta ST's soft OEM rear motor mount (RMM / 'dogbone') bushing cannot withstand the 1.6L EcoBoost's torque and the high heat at its location, so the rubber degrades and allows excessive engine movement. This produces clunking on throttle on/off, driveline shudder, and wheel… Repairs typically run $120-$500. Severity: low.
