Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented
repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall
(it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

Some 2009-2020 Ford and Lincoln vehicles equipped with turbochargers may exhibit an oil leak from the turbocharger oil supply or return tubes, O-rings or 6.7L pedestal gasket. Although oil may collect on the turbocharger, it is very rare for a turbocharger to leak oil. To isolate the source of the leak, refer to Workshop Manual (WSM), Section 303-00 General Information > Diagnosis and Testing > Engine > Engine Oil Leaks - Fluorescent Oil Additive Method procedure. When an oil leak is present at a turbocharger oil supply or drain tube, remove the affected oil tube and inspect for damage, and replace the O-ring seals, pedestal gasket or oil tube as required. Refer to WSM, Section 303-04. For c
2014-2017 Fiesta, 2015-2018 Focus, 2018-2019 Ecosport vehicles equipped with a 1.0L EcoBoost engine may exhibit coolant consumption,white smoke and/or a runs rough condition. Refer to the extended coolant pressure test in Workshop Manual (WSM), Section 303-03. If no external coolant loss is confirmed, further investigation of the integrated exhaust manifold (IEM) interface is required. Carefully inspect the manifold port area for cracks. If a crack is found, follow the cost cap tool for component replacement. Follow WSM, Section 303-01 for the repair procedures
Some 2011-2014 Fiesta and 2012-2014 Focus vehicles equipped with a DPS6 transmission may experience a fluid leak between the engine and transmission. Be aware that the engine oil and DPS6 transmission fluid are similar in color and texture. A transmission fluid leak at the input shaft seal can cause a buildup of fluid in the bell housing; creating the appearance of a rear main seal leak. The rear main seal should only be replaced after a rear main seal failure is confirmed through appropriate diagnostics outlined in the updated online Workshop Manual (WSM) Section 303-00 / Diagnosis and Testing with the use of Fluorescent dye (164-TP33200601).
This article supersedes TSB 18-2024 to update the model years. Some 2011-2018 Fiesta vehicles may exhibit a lack of heat resulting from a frozen blower motor. This may be caused by snow entering through the cowl panel grille and screen assemblies. Snow may melt in the heating, ventilation and air conditioning (HVAC) case allowing water to enter the blower motor and freeze during a below freezing overnight soak. Blower motor fuse F4 in the battery junction box (BJB) may also be open and the cabin air filter may be saturated. Follow the Service Procedure steps to correct the condition.
Some 2011-2017 Fiesta vehicles may exhibit a lack of heat resulting from a frozen blower motor. This may be caused by snow entering through the cowl panel grille and prior screen assemblies. Snow may melt in the heating, ventilation and air conditioning (HVAC) case allowing water to enter the blower motor and freeze during a below freezing overnight soak. The blower motor fuse at location F4 in the power distribution box may also be open and the cabin air filter may be water saturated. Follow the Service Procedure steps to correct the condition.

The failure pattern owners describe
The 2014 Fiesta's 1.0L EcoBoost engine exhibits two dominant failure patterns: cooling-system collapse and transmission drivability issues. Cooling failures are the most severe. Owners describe rapid coolant loss without visible leaks, combustion gases backing into the cooling system, and head gaskets cracking or warping. The engine overheating warning light typically illuminates only *after* power loss or stalling, leaving drivers no time to pull over safely. Multiple owners report the car losing all power mid-highway before any gauge indication. Repair shops cite replacement engines as the only fix, quoted between $5,000–$8,000. Ford issued NHTSA Campaign 17V209000 for this exact issue, but parts remain backordered at dealerships for extended periods, and Ford denies coverage to non-original owners despite Ford UK acknowledging the problem on their own website.
Transmission problems are persistent. Owners report jerking or shuddering during acceleration from stops or merges, with hesitation even at full throttle. Dealer fixes (module resets, clutch replacement) provide only temporary relief. One owner had the transmission serviced four times with no resolution.
Engine stalling and rough idle are common, often unaccompanied by check-engine lights. Idle surge and stalling after refueling, plus cold-start misfiring, round out the engine control issues.

Failure modes owners describe
Cooling system failure leading to head gasket and engine damage
Brittle degas line or coolant hoses fail under heat, allowing coolant to boil out undetected. Combustion gases leak into the cooling system. Head gaskets crack and warp. Coolant seeps into cylinders. Engine overheats without adequate warning from sensors, culminating in catastrophic engine failure requiring full replacement.
When: Variable; as early as 36,000 miles; some failures at 47,000-112,000 miles
Symptoms owners cite: Coolant level drops rapidly with no visible external leaks; Overheating warning light comes on only after power loss or stalling; Engine loses power and stalls without prior gauge warning; Rough idle, misfiring, car will not start; Coolant boiling in expansion tank; Spark plugs wet with coolant; combustion gases in coolant (detected via gas analyzer at 64 PPM); Extreme engine heat from interior and engine compartment; Flames under front of vehicle (one report)
Repairs/costs cited: Engine replacement quoted at $5,000–$8,000; one owner reported $1,500 in diagnostic work at independent shop before determining replacement necessary; radiator and cylinder head replacement also reported
Recalls/TSBs owners mention: NHTSA Campaign 17V209000 (Engine and Engine Cooling) issued; Ford UK acknowledges issue on their FAQ; US recall parts backordered and unavailable for extended periods (some dealers waiting 4–6 weeks); Ford denies coverage for non-original owners under the grounds that recall only applies to certain VINs; some owners report Ford refusing to service recall
Transmission jerking, hesitation, and shuddering during acceleration
Transmission module or clutch plate malfunction causes jerking or shuddering when accelerating from stop or merging into traffic. Failures persist despite multiple dealer repairs (transmission module resets, clutch replacement). Vehicle cannot achieve adequate acceleration in traffic situations.
When: 3 months into ownership (2014 model); continues through 130,000+ miles; recurring after repairs
Symptoms owners cite: Jerking motion during acceleration; Shuddering when accelerating from 10–30 mph; Vehicle fails to accelerate when merging into oncoming traffic; Hesitation with fully depressed accelerator; Transmission does not shift gears fast enough on freeway; Erratic shifting behavior; Rattle in transmission during acceleration
Repairs/costs cited: Transmission module reset performed multiple times; clutch replacement attempted but parts backordered (no ETA); repairs documented as temporary or ineffective; owners cite $724 out-of-pocket costs and extended waits
Recalls/TSBs owners mention: Ford dealer responses include 'within factory limits' and statements that clutch is backordered; manufacturer informed of failures but offered no assistance; vehicle out of warranty
Engine stalling and loss of power without warning
Engine stalls abruptly while driving or at idle without illuminating check engine or warning lights. Vehicle loses all power momentarily, requiring restart after 15–30 second delay. Occurs multiple times per drive cycle or repeatedly across days.
When: Various mileages from 8,500 to 60,000+ miles
Symptoms owners cite: Engine stalls at complete stops or in traffic; Vehicle loses power while driving at highway speed (60–70 mph); Engine surges and misfires before shutdown; No warning lights illuminate prior to stall; Engine restarts after 15–30 second delay; Failure recurs on subsequent days or drives; RPM increase without warning at stops
Repairs/costs cited: Dealers unable to duplicate failures during diagnostic; no repairs completed; one case suggests fuel rail and fuel pump replacement needed
Recalls/TSBs owners mention: Referred to NHTSA hotline; manufacturer notified but no assistance offered; some vehicles not eligible for related recalls (campaigns 15V005000, 14V402000)
Rough idle, misfiring, and cold-start hesitation
Engine idles roughly or misfires upon cold start, then improves after a few minutes of driving. Problem recurs whenever vehicle cools down. Check engine light may not illuminate despite malfunction. Condition worsens in early ownership (within weeks of purchase).
When: Within weeks of new purchase; recurring after cooling periods
Symptoms owners cite: Rough idle at start; Severe misfiring on cold start; No check engine light despite rough running; Hesitation and sputtering during low-speed acceleration; Grinding sensation on acceleration; Engine runs fine once warmed up
Repairs/costs cited: Cracked cylinder head and coolant-filled cylinders found in at least one case; complete engine rebuild or replacement required
Recalls/TSBs owners mention: No recall or warranty coverage mentioned in these reports
Idle RPM surging and stalling after refueling
After filling fuel tank, engine attempts to stall and RPM drops unpredictably during idle. Vehicle may stall completely while rolling to stops. Condition resolves after 10–15 minutes of driving.
When: Immediately after refueling
Symptoms owners cite: Idle RPM highly unpredictable after filling fuel; Engine tries to stall at red light; Stalling while rolling to a stop; Problem subsides after 10–15 minutes of driving
Repairs/costs cited: No repairs documented

Ford is saying that they have the parts to cover this recall, but they are on backorder and hard to get, and the dealers do not receive adequate parts to do the job, nor are they getting the proper instructions or training to do the job. My car has been in for 25 days, on a job that is supposed to take 5 hours, and there is no word on when or if it will ever be completed.
