What stands out
Owners have filed 282 engine complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA engine complaint has been filed on this vehicle in over 7 years — the issue may be aging out of the active population.
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.
The Powertrain Control/Emissions Diagnosis (PC/ED) manual has been revised for diagnosing electronic throttle bodies (ETBs). The ETC_ACT and ETC_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes (DTCs) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer to historical DTCs and the PC/ED, Section 3 No DTCs Present Index chart for further information.

The failure pattern owners describe
The 2010 Fusion's electronic throttle body fails repeatedly across the 282-complaint cluster, with the majority reporting sudden loss of engine power and acceleration response. Owners describe driving at highway speeds when the wrench light appears, the engine shakes and sputters, and the car slows to a crawl or stalls—requiring a restart to regain function. This happens without warning at 25 mph, 60 mph, or 75 mph, in traffic lights or on interstates. The condition is intermittent; codes clear after restart, making dealer diagnosis difficult. Many owners found online forums with identical complaints before their dealership acknowledged the issue. Some dealers refused repair because the warning light had already gone out, citing a field service action that requires the light to be illuminated. Repair costs run $261–$800 for throttle body replacement, with parts on back-order due to demand. Ford extended warranty to 10 years/150,000 miles under a customer satisfaction program, but not all vehicles qualified. One owner reported a water pump failure and catastrophic engine damage after throttle cleaning, requiring an $8,000 engine replacement. Another experienced spontaneous acceleration into a garage wall. Multiple owners escalated to Ford corporate and were denied recalls or lemon-law buybacks.

Failure modes owners describe
Electronic Throttle Body Failure
The electronic throttle body sticks, hangs, or becomes unresponsive, causing loss of engine power and acceleration. Engine does not respond to gas pedal input. Often triggered by highway speeds or acceleration from stops. Most owners report the wrench light (limp mode) appearing simultaneously. Restarting the engine temporarily fixes the symptom until it recurs.
When: Typically 1.5–6 years into ownership; reported from 35,000 to 109,000 miles
Symptoms owners cite: Loss of acceleration; gas pedal produces no response; Engine shakes, sputters, jerks, or coughs before losing power; Car slows to crawl or stalls entirely; Wrench light (limp mode) illuminates; sometimes check engine light also comes on; Rough idle and surging RPM between 500–1500; Issue clears after restart; warning light disappears; Intermittent—occurs unpredictably on highway, local roads, at traffic lights, or from complete stop
Codes mentioned: P2111 (throttle actuator stuck open), P052B (VCT solenoid phaser issue, timing-related), P211, Misfire codes (P0300 range, though owners often report these as secondary)
Repairs/costs cited: Throttle body replacement, $261–$800 depending on dealer and if labor included. Some owners cite multiple replacements (two reported). Throttle sensor replacement also recommended by some dealers. ECU flash/computer reset tried by some without permanent fix. Parts reported on back-order due to high demand.
Recalls/TSBs owners mention: Field Service Action (FSA) 13N03 and 15V793000 issued for throttle body and fuel system. Extended warranty to 10 years/150,000 miles for throttle body under customer satisfaction program. Recall issued (15V793000) but dealer interpretation varies—some refuse repair if wrench light is not currently illuminated, citing intermittent nature. No full national recall publicly announced in many narratives. Ford initially denied awareness; later acknowledged via service reps.
Stalling at Speed with Loss of Power Steering
Engine shuts down completely during highway driving, causing total loss of power assist and unresponsive throttle. Car slows and must be coasted to shoulder. Engine remains running at low idle (700–1000 RPM) but will not respond to accelerator. Restart required.
When: Throughout ownership; reported from 2 months to 5+ years after purchase
Symptoms owners cite: Sudden engine shutdown without warning during highway travel (55–75 MPH); Complete loss of power steering assist; Engine runs at low idle but does not accelerate; Wrench light comes on; sometimes check engine light as well; Engine jerks or lurches before stalling; Hazardous situation—vehicle becomes a rear-end collision risk in heavy traffic
Codes mentioned: Wrench light (limp mode indicator)
Repairs/costs cited: No code stored in most cases. Dealers clear codes upon restart. Throttle body replacement recommended and performed when diagnosis confirmed.
Recalls/TSBs owners mention: Some owners cite recall notification received after repair was made at their expense. One owner reports recall (engine throttle body) confirmed after on-road test by Ford dealer mechanic.
Rough Idle and Hesitation
Engine idles roughly, hesitates during acceleration (especially at 25, 35, 45 MPH), and sputters. May resolve temporarily after cleaning throttle body or component reset. Returns as intermittent issue.
When: Several months to years into ownership
Symptoms owners cite: Hesitation and sputtering when accelerating from stop or at low speeds; Rough idle; engine shakes when stationary; Check engine light may come on and off
Codes mentioned: Misfire codes (reported by some diagnosticians; others find only throttle-related codes)
Repairs/costs cited: Throttle body cleaning attempted; temporary improvement followed by recurrence. Spark plug and coil replacements performed in some cases without permanent fix. Some narratives describe 2-week shop stays with no diagnosis reached.
Recalls/TSBs owners mention: No specific recalls mentioned for this symptom in isolation.
EVAP Canister Purge Valve Failure
Fuel inlet check and dashboard messages related to gas inlet. Check engine light triggered. Loss of acceleration and sputtering after fueling. One owner reports EVAP canister purge valve and gas inlet assembly replacement recommended.
When: Early in ownership (~1 year reported)
Symptoms owners cite: Dashboard message to check gas inlet after fueling; Check engine light comes on; Loss of acceleration, sputtering, and engine shutdown while driving; Wrench light may come on
Repairs/costs cited: EVAP canister purge valve replacement recommended (~cost not fully stated, owner opted out). Gas inlet assembly replacement suggested ($700) but not performed by owner.
Recalls/TSBs owners mention: No recall mentioned; warranty expired.
Spontaneous Acceleration
Accelerator slowly pulls toward floor while idling into driveway, causing car to accelerate uncontrollably into garage wall. Child in vehicle during incident.
When: Not specified; occurred after normal idling maneuver
Symptoms owners cite: Accelerator slowly depresses toward floor without driver input; Car accelerates into fixed object despite braking attempt
Repairs/costs cited: Damage to vehicle and structure. Dealership did not respond to customer's call.
Recalls/TSBs owners mention: None reported.
Head Gasket Failure with Coolant Mixing into Engine Oil
Engine smoke/steam from under hood while driving. Head gasket fails; coolant leaks into engine pan and mixes with oil, causing engine overheating and potential catastrophic damage. Reported in at least one case after throttle body cleaning attempt.
When: 6 years old, 109,000 miles (one case); another at unknown mileage post-throttle repair
Symptoms owners cite: Smoke/steam pouring from under hood while driving; Rough idle and stalling at red lights (reported before steam symptom in one case); No heat; temperature gauge on hot; Battery light, check engine light, wrench light all on; Loss of power
Repairs/costs cited: Engine replacement required at $8,000. Master mechanic noted water pump crack that resealed itself, coolant mixing with oil killed engine; issue described as catastrophic with no warning signs.
Recalls/TSBs owners mention: None reported. Owner notes similar complaints in online forums but no Ford recall.
Fuel System Issue with Recall Non-Compliance
After recall repair for fuel system (NHTSA 15V793000), service engine light continues to illuminate. Dealer did not perform leak test on canister purge valve. Recall was not fully remedied.
When: Post-recall attempt at ~107,168 miles
Symptoms owners cite: Service engine light illuminates after recall repair; Light randomly flashing before recall attempt
Repairs/costs cited: Recall repair performed; code cleared. Second dealer involved; manufacturer refused further coverage.
Recalls/TSBs owners mention: Recall 15V793000 (fuel system, gasoline) issued and attempted. Manufacturer refused additional coverage after failed recall repair.
Transmission Replacement Attempted for Throttle Body Issue
One dealership initially diagnosed throttle-related stalling as a transmission problem and proposed free transmission replacement, then reneged on the commitment and denied the diagnosis was correct.
When: After multiple shop visits for stalling
Symptoms owners cite: Car shuts off while driving; Shakes and jerks
Repairs/costs cited: Transmission replacement proposed as free repair, then commitment withdrawn. Dealership later claimed transmission was not the issue.
Recalls/TSBs owners mention: Ford replacement car program suggested by service manager; owner filed claim December 1, 2011. Corporate required owner to pay ~$6,000 upfront for used vehicle mileage before replacement could proceed. Owner disputed calculation and no resolution reported.

What owners are reporting 1 most recent
2010 fusion hybrid lost power then shut down. A warning on the instrument panel said to pull over safely and stop. I have done research and found other drivers of the same make and model are having the same problem. If this were to happen in heavy traffic it could cause an accident. Apparently Ford motor is aware of the problem but has done nothing to remedy the situation. My understanding…
