    On the 2010-2020 Ford Fusion, ford Fusion Hybrid spans two generations with different high-voltage batteries — degradation patterns differ. 1st-gen 2010-2012 (NiMH, ~1.4 kWh): typical degradation appears at 100,000-150,000 miles with reduced EV-mode range and increased ICE intervention. Replacement runs $2,500-$4,000 at independent hybrid specialists. 2nd-gen 2013-2020 (Lithium-ion, ~1.4 kWh): better thermal management has led to longer life on average but cell imbalance issues appear at 150,000+ miles. 'Stop Safely Now' warnings often precede full failure. 2013-2020 Energi PHEV variants share the architecture but with larger 7.6 kWh batteries — separate degradation curve. Owners should check cell balance via OBD-II scanner with hybrid module support (Forscan recommended).

    This issue also affects: Ford C-Max, Ford Escape, Ford F-150

    Common Symptoms

    • Reduced electric-only driving range
    • Decreased fuel economy (gradual decline)
    • "Check Hybrid System" warning on dashboard
    • Slower-than-normal acceleration or power loss
    • Battery charge indicator drops faster than normal
    • Unusual noise from battery compartment area
    • Vehicle fails to start (complete battery failure)
    • Hybrid system shuts down and runs on gasoline only

    How to Fix

    Check warranty first - Ford covers 8yr/100k miles (10yr/150k in CA, CT, MA, ME, MD, NJ, NY, OR, PA, RI, VT, WA states). If out of warranty, aftermarket/remanufactured battery packs from GreenTecAuto ($1,550-2,950 installed) are significantly cheaper than dealer replacement ($4,000-7,000). Individual cell replacement at specialized hybrid shops ($800-2,000) is an option if only specific cells have failed. Battery reconditioning is a temporary fix that may restore 60-80% of capacity for $300-800.

    Typical repair cost:$1,500 - $7,000

    On the 2010-2018 Ford Fusion, many Fusion owners report the battery going dead overnight or over a weekend from a parasitic draw. Common culprits are a module that fails to sleep - Body Control Module (BCM), APIM/infotainment, or amplifier - as well as the PATS anti-theft transceiver circuit on earlier cars. A healthy vehicle should draw under ~50mA at rest; failed modules keep the network awake and flatten the battery.

    This issue also affects: Ford Escape, Ford Transit Connect, Ford Edge

    Common Symptoms

    • Battery dead after sitting overnight or a weekend
    • Frequent jump-starts required
    • Clicking / no-crank no-start
    • Electrical gremlins or flickering
    • Short battery life

    How to Fix

    Measure key-off current draw with a multimeter, then pull fuses one at a time until the draw drops to isolate the offending circuit/module. Repair or replace the module that will not sleep (commonly BCM, audio/APIM, or amplifier); reflash where required. Confirm the battery and alternator test good before condemning a module.

    Typical repair cost:$150 - $1,000

    On the 2011-2013 Ford Fusion, nHTSA recall 15V340 covers 2011-2013 Ford Fusion (and Lincoln MKZ) without the 3.5L engine. An intermittent electrical connection in the steering gear can cause sudden loss of electric power steering assist while driving. Owners notice heavier steering effort especially at low speeds, increasing crash risk. Dealers check the Power Steering Control Module (PSCM) for DTCs; if any loss-of-assist codes are stored, the steering gear is replaced free. Note: 2010 Fusions had the same parts but were excluded from the recall — feds closed the probe without expanding scope. 2010-owner symptoms are real but uncovered by recall.

    This issue also affects: Ford C-Max, Ford Escape, Ford Explorer

    Common Symptoms

    • Power steering warning message on dashboard
    • Steering becomes heavy or requires extra force
    • Intermittent loss of power steering assist
    • Steering wheel off-center after loss of assist
    • Clunking or grinding from steering column area
    • Complete loss of power steering (requires significant force to turn)
    • Steering assist comes and goes unpredictably
    • Check engine light or power steering fault code stored

    How to Fix

    Check if your vehicle is covered under Ford recall (2011-2012 Fusion/MKZ power steering failure recall - free repair). For non-recall vehicles, the electric power steering rack must be replaced as a complete unit since the motor and control electronics are integrated. RepairPal estimates $1,958-3,362 installed. Remanufactured racks from PWR Steer or Cardone are available at $800-1,500, significantly cheaper than new OEM ($2,000+). Have the alignment performed after rack replacement.

    Typical repair cost:$1,200 - $3,500

    On the 2010-2016 Ford Fusion, the electronic throttle body suffers internal contamination/wear of the motor contacts, causing intermittent electrical failure rather than simple dirt buildup. The result is a sudden loss of power (limp/failsafe mode) with the amber wrench (powertrain) warning light, rough idle, or stalling, sometimes in traffic. Ford acknowledged the problem with extended-warranty program 13N03 for 2010-2013 models and Customer Satisfaction Program 16B32 for certain 2015-2016 vehicles including Fusion.

    This issue also affects: Ford Edge, Ford Escape, Ford Explorer

    Common Symptoms

    • Wrench/powertrain warning light
    • Sudden loss of power / limp mode
    • Rough or surging idle
    • Stalling
    • Reduced throttle response

    How to Fix

    For the limp-mode failure the throttle body must be replaced (cleaning does not fix internal electronic wear), followed by a mandatory throttle-body relearn to prevent high idle and driveability faults. Check whether the vehicle qualified for 13N03 or 16B32 coverage history.

    Typical repair cost:$250 - $550

    On the 2010-2019 Ford Fusion, on AWD Fusions the Power Transfer Unit holds only about a quart of gear oil with no dipstick, service interval, or cooling, sitting next to hot exhaust and transaxle. The fluid cooks and breaks down, becoming thick, gummy, and black, and the seals leak. Owners report a burning smell in the cabin, whining/growling, and eventually PTU seizure that can damage the transmission. Failures often occur relatively early in the car's life.

    This issue also affects: Ford Edge, Ford Escape, Ford F-150

    Common Symptoms

    • Burning oil smell in cabin
    • Whining, growling, or grinding from center of vehicle
    • Brown/black fluid leak near transaxle/axle area
    • Vibration or shudder under acceleration
    • Loss of AWD function

    How to Fix

    Preventive fluid changes roughly every 30,000 miles greatly extend PTU life even though Ford lists it as filled-for-life. A leaking unit may be resealed for $400-$600 if caught early; a failed PTU requires replacement, which dealers quote from ~$1,600 up to ~$3,100 including labor.

    Typical repair cost:$400 - $3,100

    On the 2010-2019 Ford Fusion, the 6F35 six-speed automatic is prone to harsh, banging, or delayed shifts (most often 2-3 and 3-4) plus a shudder/vibration when the torque converter clutch locks up at a steady 40-60 mph cruise. Root causes are worn valve-body separator-plate O-rings and bores that can no longer hold clean line pressure, clogged/worn shift solenoids, and torque-converter clutch degradation. Many units develop symptoms well before 100,000 miles. A 2019 class-action lawsuit accused Ford of concealing the 6F35 defect on Fusion and Escape.

    This issue also affects: Ford Aerostar, Ford Bronco, Ford Contour

    Common Symptoms

    • Hard/banging upshifts especially 2nd-to-3rd
    • Shudder or vibration cruising at 40-60 mph
    • Delayed engagement into drive or reverse
    • Slipping or flaring between gears
    • Transmission overheating warning

    How to Fix

    Start with a full fluid-and-filter service using the correct Mercon LV. For confirmed harsh shifts, reman or updated valve body with new solenoids is the durable fix; TCC shudder that survives a flush usually requires torque-converter replacement. Verify the transmission calibration is up to date (Ford released updated shift-strategy PCM/TCM reflashes). Severe internal wear = rebuild or reman transmission.

    Typical repair cost:$250 - $3,500

    On the 2006-2020 Ford Fusion, the plastic gears inside the HVAC blend-door actuator strip out, so the door can no longer move to route air correctly. The classic symptom is a repeated clicking or knocking noise from behind the dash (often at startup or when changing temperature), along with air stuck on one temperature, wrong vent output, or one side blowing hot while the other blows cold. It is one of the most common Fusion comfort complaints across all generations.

    This issue also affects: Ford Edge, Ford Escape, Ford F-150

    Common Symptoms

    • Repeated clicking/knocking noise behind dashboard
    • No heat or no cold air from vents
    • Temperature stuck on hot or cold
    • Different temperature from left vs right vents
    • Air blows from wrong vents

    How to Fix

    Replace the failed blend-door actuator (driver side of the HVAC housing, accessed by dropping the glove box). After replacement, perform the actuator calibration: reconnect the battery, turn ignition to On without starting, and let the system self-learn its range for at least a minute. Parts are inexpensive; labor rises sharply if a deeper actuator requires dash removal.

    Typical repair cost:$156 - $400

    On the 2010-2012 Ford Fusion, the under-hood evaporative-emissions purge valve on 2010-2011 Fusion/Milan (2.5L DOHC and 3.0L) built on or before 3/4/2011 can stick open or leak, unmetered vapor entering the intake. This lights the MIL and sets a cluster of EVAP and lean/fuel-trim codes, and can cause rough idle or hard starts. It is a documented Ford pattern failure with a related TSB covering the affected build range.

    This issue also affects: Ford Escape, Ford Mustang, Ford Ranger

    Common Symptoms

    • Check engine light on
    • Rough idle or stalling
    • Hard start after refueling
    • Fuel smell
    • Failed emissions test

    How to Fix

    Confirm the purge valve holds vacuum and clicks when energized; replace the stuck/leaking purge valve (inexpensive part). Verify no cracked EVAP hoses, a properly sealing gas cap, and an intact charcoal canister before clearing codes. Smoke-test the EVAP system if large-leak codes persist.

    Typical repair cost:$100 - $300
