Owners consistently describe a fuel system that works against them. The fuel tank warps or deforms, making it impossible to fill beyond a quarter tank without the vehicle stalling—contradicting Ford's own recall guidance to keep the tank half full. When owners do refuel, the vehicle shakes violently, makes loud noises, and often stalls immediately after, requiring extended restart times. The fuel gauge gives false readings, leaving drivers uncertain of their fuel level and stranded.
The canister purge valve fails regularly, preventing the EVAP system from venting fuel vapors correctly. This triggers stalling, rough idle, and hesitation during acceleration. One owner replaced this valve only to have the check engine light remain illuminated and the stalling continue. Owners also report the vehicle cannot idle for more than five minutes without dying—a serious problem in stop-and-go traffic.
Transmission troubles compound the misery. The dual-clutch shudders during acceleration from a stop, downshifts without warning, and fails repeatedly. One owner's clutch replacement lasted only six months before the shudder returned. Some repairs like mass airflow sensor replacement have failed within two days.
The biggest frustration is that recall parts—fuel tanks, valves, and other components—remain unavailable for months or longer. Dealers cannot complete recall work, leaving vehicles unrepaired despite known issues. Several owners completed recalls in 2019 only to experience the same failures months later, with Ford refusing further assistance because the recall had expired.
Failure modes owners describe
Fuel tank deformation and fuel gauge failure
Fuel tank warps or deforms, causing inaccurate fuel gauge readings, inability to fill beyond 1/4 tank without stalling, and vehicle shake/noise during refueling. Owners report pump cutoff issues and tank sloshing sounds.
When: 30,000–145,000 miles
Symptoms owners cite: Inaccurate fuel gauge readings; Vehicle shakes and makes loud sound while refueling; Cannot pump fuel beyond 1/4 tank without stalling; Vehicle stalls if overfilled; Fuel pump cutoff malfunction; Gasoline odor from oil pan
Codes mentioned: P1450 (canister purge valve-related)
Repairs/costs cited: Fuel tank replacement; one owner replaced fuel tank and pump module for approximately $30,000 combined with other repairs. Some dealers quote 6+ months for parts availability.
Recalls/TSBs owners mention: NHTSA Campaigns 18V735000, 19V515000, 14V525000, 15V005000 (Fuel System); recall 18S32 (fuel tank deformation); TSB Ford Campaign 24N07 (canister purge valve). Some owners completed recall work in 2019 but continued experiencing issues post-recall.
Stalling during and after refueling
Vehicle stalls immediately after refueling or during driving shortly after refueling. Stalls can occur at any speed with loss of motive power. Vehicle requires extended restart time (15–60 minutes or more) or multiple restart attempts.
When: 16,000–160,000 miles
Symptoms owners cite: Loss of motive power while driving; Vehicle stalls during or immediately after refueling; Extended restart time required (15–60+ minutes); Multiple restart attempts needed; Check engine light illuminated during stalling events
Codes mentioned: Check engine light (code not always retrieved)
Repairs/costs cited: No repairs completed in most complaints; one owner added 9 gallons of fuel as temporary fix. Canister purge valve replacement ($cost not cited) attempted but did not resolve issue.
Recalls/TSBs owners mention: NHTSA Campaigns 18V735000, 19V515000, 14V525000 address stalling post-refuel. Dealers unable to complete repairs due to expired recalls or unavailable parts.
Canister purge valve (CPV) and EVAP system failure
Canister purge valve sticks or fails, preventing proper fuel vapor venting and causing stalling, hesitation, and rough running. EVAP system malfunction diagnosed by multiple independent mechanics and dealers.
When: 70,000–180,000 miles
Symptoms owners cite: Vehicle stalls with check engine light; Engine hesitation during acceleration; Rough idle and erratic RPM fluctuation; Failure to start immediately after refueling; Check engine light remains illuminated after purge valve replacement
Codes mentioned: P1450 (canister purge valve control circuit)
Repairs/costs cited: Canister purge valve replacement (cost not cited); one owner replaced purge valve but failure recurred. Another owner had purge valve replaced but check engine light persisted.
Recalls/TSBs owners mention: NHTSA Campaigns 19V515000 and 18V735000 address CPV; Ford Campaign 24N07 covers canister purge valve. Many VINs reported not included in recalls despite matching symptoms.
Idle stalling and inability to hold idle
Vehicle stalls while idling or in traffic if engine not kept in motion every 5 minutes. RPM fluctuates erratically while idling. Repeated stalling at stops, especially on inclines.
When: 50,000–115,000 miles
Symptoms owners cite: Stalling while idling in traffic; Vehicle requires constant driving motion to prevent stall; RPM fluctuates while stopped; Vehicle rolls backward on inclines after brake release; Cannot remain idle for more than 5 minutes without stalling
Repairs/costs cited: No repairs completed; one owner noted battery drain from repeated stalling and idling events.
Recalls/TSBs owners mention: Advice given to keep tank at least half full (contradicted by owners' inability to fill past 1/4 tank).
Transmission hesitation, shudder, and clutch failure
Transmission downshifts without warning, vehicle shudders during acceleration from 1st to 2nd gear, and dual-clutch transmission fails repeatedly. Clutch seal and disengagement mechanism wear prematurely. Some clutch replacements fail within 6 months.
When: 40,000–113,000 miles
Symptoms owners cite: Vehicle shudders and jerks during acceleration; Transmission downshift without warning (3rd to 1st, especially downhill); Hesitation when upshifting; Inability to shift into reverse; Transmission fault warning light illuminated; Clutch disengagement failure
Codes mentioned: Transmission fault warning light
Repairs/costs cited: Clutch seal replacement, clutch assembly replacement, transmission fluid change, TCM (transmission control module) replacement, and electronic updates performed. Repairs cost not cited; one owner noted clutch replacement lasted only 6 months before shudder recurred.
Recalls/TSBs owners mention: NHTSA Campaign 19V515000 partially addresses transmission issues; some dealers replaced clutch and performed updates but failures recurred. TCM replacement covered under Ford Campaign 24N07 for some.
Poor acceleration response and power loss
Engine fails to respond to accelerator pedal depression; vehicle loses motive power during acceleration or highway driving. Hesitation is intermittent and unpredictable, sometimes severe enough to cause near-accidents.
When: 60,000–190,000 miles
Symptoms owners cite: Delayed engine response to pedal input; Complete loss of power while accelerating; Vehicle loses power on highway at speed; Hesitation and stumble during acceleration from stop; Inability to climb hills with pedal fully depressed
Codes mentioned: Check engine light (often no code retrieved)
Repairs/costs cited: Fuel pump replacement attempted by independent mechanic (cost not cited); mass airflow sensor replacement performed but failure recurred within 2 days.
Recalls/TSBs owners mention: NHTSA Campaigns 18V735000 and 19V515000 linked; some dealers unable to diagnose (no code found) or unable to repair due to recall status.
Fuel pump and fuel system component failure
Fuel pump fails or produces insufficient pressure, and fuel pump module requires replacement. Valve (likely pressure regulator or pump inlet valve) becomes inoperable, and fuel tank becomes warped and uneven.
When: 70,000–120,000 miles
Symptoms owners cite: Vehicle fails to start or start reluctantly; Vehicle stalls after extended idle or at rest; Loss of power while driving
Repairs/costs cited: Fuel tank, fuel valve, and fuel pump replacement required (cost not cited). One independent mechanic cited fuel pump replacement need.
Recalls/TSBs owners mention: Linked to NHTSA Campaign 19V515000 by owner; manufacturer response not documented.
Check engine light and diagnostic trouble code issues
Check engine light illuminates but no diagnostic trouble code is retrievable by dealer scan tools. Intermittent faults prevent code capture. Light remains on after purge valve or other repairs.
When: Various, 30,000–145,000 miles
Symptoms owners cite: Check engine light illuminated with no retrievable code; Light returns intermittently; Light remains on after component replacement
Codes mentioned: No code retrieved (intermittent fault)
Repairs/costs cited: Independent mechanics reset code multiple times; light recurred. Dealer unable to diagnose due to lack of code.
Recalls/TSBs owners mention: Dealers unable to proceed with repairs if no code is present; directed owners to NHTSA.
Recall part unavailability and incomplete recall repairs
Ford unable to supply parts for fuel system recalls (18V735000, 19V515000, 14V525000) for extended periods, ranging from weeks to 6+ months. Two-part recalls left incomplete (one part repaired, second part deferred).
When: At time of recall notification (2018–2022)
Symptoms owners cite: Recall notice received but dealer cannot schedule repair; Parts on back-order indefinitely; Manufacturer cannot confirm parts availability timeline; Recall repair splits: one component fixed, another deferred
Repairs/costs cited: No repairs completed; dealers documented 'parts not available.' Multiple owners reported delays exceeding 6 months.
Recalls/TSBs owners mention: NHTSA Campaigns 18V735000, 19V515000, 14V525000 issued but parts supply chain failed to support timely repairs. Manufacturer unable to confirm availability dates. Some recalls expired before parts became available.
