SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DISC:CALIPER
Ford Motor Company (Ford) is recalling certain 2019 Fiesta vehicles. The brake calipers may have been manufactured with the incorrect assembly fluid, which can cause the caliper's rubber seals to swell.
BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
Ford Motor Company (Ford) is recalling certain 2019 Flex, Fiesta, and Lincoln MKT vehicles. The rearview camera may intermittently display a blank or distorted image.
BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

The 2015 Ford Fiesta has 28 known issues documented across 1,830+ owner reports. 9 issues are rated critical: DPS6 PowerShift Dual-Clutch Transmission Shudder, Slipping, and Failure and Door Latch Failure — Doors May Open While Driving and Electronic Throttle Body Failure — Sudden Limp Mode & Wrench Light and 1.0L EcoBoost Degas Hose Coolant Loss & "EcoBoom" Overheating Engine Failure and DPS6 Transmission Control Module (TCM) Failure — Loss of Engagement, No-Start, U0101 (Extended Warranty 14M02) and Electric Power Steering (EPS) Assist Fault — Sudden Loss of Assist and Wet Belt (Belt-in-Oil) Timing Belt Degradation Clogging Oil Pump Pickup and Fiesta ST 1.6L EcoBoost Cylinder Head Overheat, Crack & Oil Leak Fire Risk — Coolant Level Sensor Recall (17V209) and In-Tank Fuel Pump Failure — Stall Without Warning (Recall 15V005000). Prospective buyers should inspect for these issues and factor potential repair costs into their purchase decision. Regular maintenance following the manufacturer's schedule helps prevent many common problems.
Repair costs for known Ford Fiesta issues range from $0 to $8,000, depending on the specific problem and whether you choose DIY or professional repair. The most critical issue, DPS6 PowerShift Dual-Clutch Transmission Shudder, Slipping, and Failure, typically costs $0-$3,500 to repair. Au7o provides step-by-step DIY maintenance guides that can help reduce repair costs.
The Ford Fiesta equipped with the DPS6 PowerShift dual-clutch automatic transmission is one of the most complained-about vehicles in recent history. The dry dual-clutch design causes severe shuddering, jerking, hesitation, and complete loss of power during acceleration. The clutc… Repairs typically run $0-$3,500. Severity: high.
Ford recalled over 2 million vehicles including 2011-2015 Fiesta sedans and hatchbacks because of faulty door latches that can break internally. When the latch fails, the door may not close securely or may open unexpectedly while the vehicle is moving. The problem is caused by a… Repairs typically run $0-$300. Severity: high.
The drive-by-wire electronic throttle body (ETB) develops an internal electronic/motor fault (not just dirt) that causes the powertrain control module to command reduced power. The car drops into limp mode with a wrench/powertrain-malfunction light, often storing throttle-positio… Repairs typically run $250-$700. Severity: high.
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.
Separate from the clutch-pack shudder already documented: the DPS6 PowerShift's Transmission Control Module, mounted on the transmission and exposed to heat, fails electrically. The car suddenly loses drive while moving, will not start, drops into limp mode, or the cluster throws… Repairs typically run $0-$1,200. Severity: high.
Fiestas can display 'Power Steering Assist Fault — Service Required' and lose electric power-steering assist, sometimes intermittently while driving. Root causes include torque-sensor faults and intermittent electrical connections in the steering column/gear that stop the control… Repairs typically run $350-$1,500. Severity: high.
The 1.0L EcoBoost uses a 'wet' timing belt that runs submerged in engine oil. When oil is old, over-extended, or not to Ford's WSS-M2C948-B spec, the belt's rubber breaks down and delaminates ('pilling'). Shed fragments migrate through the sump and clog the oil pump pickup screen… Repairs typically run $600-$8,000. Severity: high.
Distinct from the 1.0L EcoBoost degas-hose failure: the 1.6L EcoBoost in the 2014-2015 Fiesta ST has cylinder-head coolant passages that develop localized hot spots. If coolant is lost (the ST has no low-coolant warning from the factory), the head overheats and can crack, leaking… Repairs typically run $0-$6,000. Severity: high.
Improper nickel plating of internal components in the Bosch in-tank fuel pump can cause the pump to fail, letting the engine stall without warning and increasing crash risk. Ford issued NHTSA recall 15V005000 covering certain 2014-2015 Fiesta (and related Fusion/MKZ) vehicles bui… Repairs typically run $0-$900. Severity: high.
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.
Fiestas — especially the 1.6L EcoBoost ST — commonly throw misfire codes and run rough at idle from failing ignition coils and fouled spark plugs. Owners report oil creeping onto the coil boots and, notably, rainwater entering the spark-plug wells via the washer-jet routing, whic… Repairs typically run $150-$550. Severity: medium.
The naturally aspirated 1.6L Ti-VCT (Sigma) engine in 2011-2019 Fiestas uses oil-pressure-driven cam phasers controlled by VCT solenoids. Dirty oil, extended drain intervals, or small debris cause the solenoid to stick, and worn phasers rattle for a few seconds on cold start. The… Repairs typically run $40-$1,200. Severity: medium.
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.
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. This is a very frequently reported Fiesta failure — front springs are most commonly cited but… Repairs typically run $200-$500. Severity: medium.
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.
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.
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.
Fiestas fitted with rear discs (ST, Titanium and higher EU trims) suffer seized rear caliper slide pins and stuck parking-brake actuating levers. Road salt corrodes the pins and the lever pivot, so the pad drags constantly: rapid inner-pad wear, a hot wheel and burning smell afte… Repairs typically run $60-$500. Severity: medium.
Rear wheel bearings on the Mk7-generation twist-beam Fiesta (including the ST) wear prematurely, producing a hum or drone that rises with road speed and changes pitch when the car is loaded in a corner. Ford Owners Club, FiestaSTOC and fiestastforum all carry multiple threads, wi… Repairs typically run $150-$700. Severity: medium.
Separate from DPF regeneration failures: the 1.4 TDCi and 1.6 TDCi diesels sold in Europe (2008-2017) clog their exhaust-gas-recirculation valve with soot and oil residue, especially on short-trip, stop-start use. The valve sticks partially open or closed, the ECU logs an EGR flo… Repairs typically run $80-$500. Severity: medium.
