What stands out
Owners have filed 90 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.
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.
CERTAIN 2011-2012 MODEL YEAR FUSION VEHICLES EQUIPPED WITH 2.5L OR 3.0L ENGINES - POWERTRAIN CONTROL MODULE REPROGRAMMING AND CANISTER PURGE VALVE INSPECTION
full bulletin at NHTSA ↗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 2011 Ford Fusion engine cluster involves a chronic electronic throttle body (ETB) defect that owners describe as dangerous and recurring. Most commonly, drivers lose all accelerator response without warning—the engine drops to a limp 1,000 RPM, the wrench light illuminates, and the car either coasts to a stop or slows dangerously. This happens at highway speeds (55–70 MPH) in traffic, across multiple lanes, and sometimes on interstates with no shoulder. Restarting the engine clears the fault temporarily, but the problem resumes within minutes to days. Owners report this occurring 5–10+ times in short periods. Dealerships confirm throttle body replacement is needed, but parts are chronically backordered 4–6+ weeks, leaving cars undriveable. When cars do get fixed, the failure recurs at higher mileage (50K, then 100K). Hard starting (3–5 cranking attempts), stalling at idle, and EVAP system faults (check fuel inlet messages, P0455/P0456 codes) also plague these vehicles within months of purchase. One owner's car caught fire after extended freeway operation. Ford issued investigation PE13003 and a software calibration (CSP 13N03), but owners report the update doesn't fix the problem—dealerships still replace the part with an identical unit. Out-of-warranty repairs run $400–$600 for the throttle body alone, and diagnostics can cost $80–$120 upfront. The narratives make clear owners see this as a safety defect Ford knows about but has not recalled.

Failure modes owners describe
Electronic Throttle Body (ETB) Failure – Sudden Power Loss
The electronic throttle body malfunctions, causing abrupt loss of engine power and acceleration failure during normal driving. Engine remains running but will not respond to throttle input. Vehicle enters 'limp mode,' dropping to approximately 1,000 RPM with no ability to accelerate. Wrench and check engine lights illuminate. Power returns after turning engine off and restarting.
When: Typically occurs within first few months to 2 years of ownership; reported from 1,500 miles to 189,000 miles; frequently happens at highway speeds (35–70 MPH) or in intersection/traffic situations
Symptoms owners cite: Sudden complete loss of engine power while driving; Vehicle coasts or slows to 2–10 MPH unresponsively; Car shakes, bucks, jerks, or sputters; Wrench (limp-mode) warning light illuminates; Check engine light comes on; Engine runs rough or idles at elevated RPM (1,000–2,000); No response to throttle pedal input; Power returns after shutdown and restart; Failure recurs within minutes to weeks
Codes mentioned: P2111, P2112, P0455, P0456
Repairs/costs cited: Throttle body replacement; dealerships report chronic backorders (4–6+ weeks); repair costs $400–$600 when out of warranty; some owners charged $50–$122 for dealer diagnostics; parts frequently not available from manufacturer
Recalls/TSBs owners mention: NHTSA Investigation PE13003 (Electronic Throttle Body Malfunction); CSP 13N03 (Campaign/Settlement Program); Ford issued TSB and PCM software calibration updates; however, owners report calibration ineffective and some dealerships claim manual-transmission vehicles or non-Mexico-assembled units not covered; no full recall issued despite widespread complaints
Hard Starting / Cranking Issues
Vehicle requires multiple attempts (3–5 times) to start, especially after warm engine operation or short stops. Engine cranks but resists turning over; may take 20+ seconds. Owners also report backfiring and rough start-up followed by high idle RPM.
When: Within first 3 weeks to several months of ownership; occurs most frequently with warm engine after short intervals away from vehicle
Symptoms owners cite: Engine cranks repeatedly before starting; Prolonged cranking time (20+ seconds); Vehicle stalls immediately after starting; Engine backfires; High idle RPM (1,500–2,000) after restart; Strong gasoline smell during episodes
Repairs/costs cited: Some dealers attributed to fuel system issues (no gas cap, fuel inlet debris); cleaning fuel inlet reported but issue recurred; no permanent repair documented in narratives
Recalls/TSBs owners mention: Dealers blamed incorrect gas-cap fitment or seasonal fuel blend changeover (winter to summer gasoline); no recall or TSB cited by owners
Check Fuel Fill Inlet / Evaporative (EVAP) System Faults
Check engine light and 'Check Fuel Fill Inlet' message display repeatedly. Evaporative purge valve or canister purge solenoid fails, triggering EVAP system leak codes. Issue persists after fuel inlet cleaning and part replacement attempts.
When: As early as 2 weeks after purchase; reported through 200,000 miles
Symptoms owners cite: Check Fuel Fill Inlet message on dashboard; Check engine light illumination; EVAP system leak detection codes (P0455, P0456); Message clears temporarily with reset but returns; Strong fuel smell reported

Recalls/TSBs owners mention: NHTSA Campaign 15V793000 (Fuel System, Gasoline) issued; some owners reported repair did not correct the failure; dealers initially told owners this was common in cars without proper gas caps
Transmission Slip / Transmission Control Issues
Transmission exhibits slipping, jerking, or failing to shift properly. Vehicle acts as if in neutral when accelerating. Transmission reportedly died on one vehicle. RPM floats without power transfer to wheels.
When: Within first few months of ownership; reported at various mileages
Symptoms owners cite: Transmission slips on acceleration; Car jerks forward violently during gear engagement; Vehicle acts as if in neutral when pedal depressed; RPM increases but no power transferred to wheels; Transmission warning light may illuminate
Repairs/costs cited: One owner reports TSB reset (PCM recalibration) performed but ineffective; transmission not repaired; AC system also malfunctioned after reset
Recalls/TSBs owners mention: Dealers performed PCM (powertrain control module) reset per TSB; however, owners report continued problems and side effects (AC failure)
Engine Stalling – Intermittent Loss of Idle Control
Engine stalls while idling at traffic lights, in parking lots, or during normal low-speed driving. Vehicle exhibits unstable or high idle RPM (2,000+). Engine restarts but continues to stall intermittently.
When: Typically within first 1–4 months of ownership; occurring daily or multiple times per week
Symptoms owners cite: Engine dies while idling at red light or in park; Stalls during low-speed maneuvers (parking lots, yield situations); High idle RPM (2,000) after restart; Strong gasoline odor; Wrench or check engine light may illuminate
Repairs/costs cited: Dealers unable to reproduce issue during diagnostics; one owner attributed to seasonal fuel changeover but issue recurred despite explanation
Recalls/TSBs owners mention: Dealership diagnostics inconclusive; no service bulletins or recalls cited by owners
Unintended Acceleration / Loss of Brake Control
Engine accelerates while foot is firmly on brake pedal. Vehicle inches forward or rolls despite brake engagement. Shifting to Neutral or Park does not stop acceleration. Issue resolves only when engine is turned off.
When: Reported at least twice in one owner account; occurred during slow-speed situations (stop light, parking lot)
Symptoms owners cite: Engine accelerates with foot on brake; Vehicle rolls forward despite brake pedal pressure; Shifting to Neutral or Park does not stop acceleration; Acceleration continues until engine manually shut off
Repairs/costs cited: Dealership diagnostic inconclusive; stated vehicle 'functioned as designed'
Recalls/TSBs owners mention: Dealer stated vehicle operated as designed; no repair attempted; no recall or investigation mentioned
Mass Air Flow (MAF) Sensor Failure
MAF sensor voltage reading out of specification (.58V instead of .75V), leading to loss of power and stalling. Check engine and electronic throttle control warnings illuminate.
When: At 85,881 miles
