What stands out
Owners have filed 59 electrical 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 electrical complaint has been filed on this vehicle in over 16 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2006 Fusion has serious, widespread electrical and engine control issues—ignition coils burning out without warning and causing highway stalls, smart junction boxes failing to control turn signals, and throttle bodies refusing to respond. Plan for $600–$2,200+ in repairs and expect to be out of pocket since Ford issued no recalls despite knowing about these defects.
Owners describe a litany of electrical gremlins and engine-control failures. The most dangerous: ignition coils short internally or burn out the power control module, killing the engine without warning at highway speeds, leaving drivers coasting to the shoulder and risking rear-end collision. One owner nearly died when stalled in traffic; another spent $1,462 in repairs. A technical service bulletin (TSB 11-8-2) addresses this, but Ford has not issued a recall.
Turn signal circuits fail regularly due to a faulty smart junction box. Owners replace bulbs only to find parking lights stay on after ignition off, draining the battery. The dashboard warns "check turn signal," but bulbs and fuses are fine—the junction box has failed internally. Replacement costs $600–$850 and Ford no longer manufactures the part, forcing junkyard sourcing.
Interior door handles warp, crack, or short-circuit and explode. Doors can only be opened from outside. Stuck ignition keys require jiggling the shifter button to achieve Park; dealers blame the driver, not the broken plastic shifter mechanism.
Throttle bodies malfunction unexpectedly, cutting power during highway merges or causing limp-mode activation. AC temperature sensors fail, blowing only warm air and fogging windshields. Owners report replacing throttle bodies twice, alternators, and belts—all to no avail.
Ford's consistent response: no recall, no warranty coverage after the initial period, and owner pays full repair costs.

Failure modes owners describe
Ignition coil/PCM failure causing engine stall
Factory ignition coils short internally or fail, burning out the power control module (PCM). Owners report the PCM or coils burn, overheat, or 'explode,' leading to catastrophic engine shutdown without warning while driving at highway speeds. Computer malfunction is cited as root cause. Diagnostic codes reference TSB 11-8-2.
When: Typically between 65,000 and 124,000 miles; can occur early with no warning
Symptoms owners cite: Engine shuts off without warning while driving; Check engine light flashing or illuminating; Traction control warning light; Throttle control warning light; Engine will not respond to throttle after stall; Misfiring and rough idle; Loss of power steering upon stall
Codes mentioned: TSB 11-8-2, P0300 range (misfire), Check Engine Light
Repairs/costs cited: Replacement of PCM, ignition coils (6), spark plugs (6), valve cover gasket, tube seals, air filter element, and PCM programming at Ford dealer. Owners report costs ranging from $1,200 to $2,200+. Repair may require tow to dealer.
Recalls/TSBs owners mention: TSB 11-8-2 issued for PCM replacement. No recall despite acknowledged defect in PCMs for 2006-2008 Ford Fusions, 2008 Taurus, 2007-2008 Edge, 2006 Lincoln Zephyr, 2007-2008 Lincoln MKZ/MKX, and 2006-2008 Mercury Milan/Sable. Owners over 8-year/80,000-mile warranty denied coverage.
Smart Junction Box (SJB) electrical failure
The smart junction box malfunctions or fails internally, causing widespread electrical gremlins. Some units show signs of moisture intrusion or internal melting. Turn signals, parking lights, and battery drain issues commonly result. Box is no longer manufactured by Ford, forcing owners to search junkyards for replacements.
When: Reported as early as 34,000 miles; most commonly 80,000-120,000 miles range
Symptoms owners cite: Front turn signals stop working; Parking lights stay on after ignition off; Brake lights and rear blinkers inoperative; Dashboard warning messages for turn signal bulbs; Battery drains due to lights staying on; Turn signal bulbs burnt/blackened prematurely; High-speed blinking of rear signals; Hazard lights inoperative; Possible moisture intrusion after heavy rain
Codes mentioned: SJB failure (no OBD code, diagnosed by dealer/mechanic)
Repairs/costs cited: Complete SJB replacement required. Owners report costs $600–$850+ including parts and labor. Part is no longer in production; some report needing junkyard sourcing. Replacement must be programmed by Ford dealer.
Recalls/TSBs owners mention: No recall issued. Dealers have stated SJB failure is not a safety issue despite malfunctioning turn signals and battery drain hazards. No warranty coverage once vehicle exceeds initial warranty period.
Stuck ignition key
The ignition key will not release from the ignition switch after turning off the vehicle. Owners report having to jiggle or manipulate the shift lever button to achieve the correct position to release the key. Underlying cause is a broken or worn shifter button mechanism that prevents the car from registering Park position, which locks the key.
When: Reported across mileage range; early examples at 23,000–24,000 miles and later at 92,000 miles
Symptoms owners cite: Key stuck in ignition after vehicle shut off; Key cannot be removed without repeated attempts; Must jiggle shifter button to find 'happy spot' for key release; Plastic shifter button breaking or wearing out; Vehicle not registering Park position
Repairs/costs cited: Dealers quote $400–$500 for shift assembly replacement or $180 for key cylinder replacement alone. One owner reported needing to remove plastic pieces to extract key. Some dealers blame driver error.
Recalls/TSBs owners mention: No recall. Dealers acknowledge failure as common in 2006 Fusion models but offer no warranty coverage beyond initial period. Owner reported being told by manufacturer that exceeded-warranty vehicles are not their responsibility.
Interior door handle malfunction
Interior door handles warp, bend, break, or fail to operate. In some cases, the handle short circuits and explodes, destroying the mechanism. Locking mechanism also malfunctions, preventing doors from locking or unlocking. Owners may become trapped if windows fail or in crash situations.
When: Reported with worn interior door handles (plastic deformation); one explosion incident noted
Symptoms owners cite: Interior door handle warps or bends; Door handle breaks or cracks; Handle short circuits and explodes; Door cannot be opened from interior; Door locking/unlocking mechanism fails; Door can only be opened from outside; Vehicle cannot be locked via key or remote; Trapped occupants if windows malfunction
Repairs/costs cited: Replacement handles and/or locking mechanism assembly required. Cost not specified in narratives. Plastic deterioration suggests design defect in material or manufacturing.
Throttle body malfunction / limp mode activation
Throttle body sticks open or closed, preventing normal engine response. Vehicle enters limp mode (reduced power) or loses throttle response entirely. Owners report sudden loss of acceleration, particularly during highway merging or at higher speeds. Engine idle becomes rough or rough when issue occurs.
When: Reported from early ownership through higher mileage; one case at 72,000 miles leading to crash
Symptoms owners cite: Loss of throttle response when accelerating; Engine drops to idle and will not accelerate; Wrench light (limp mode indicator) illuminates; Vehicle enters reduced-power limp mode; Misfiring and bucking sensation; Rough idle; Check engine light may appear; Issue resolves temporarily after engine restart
Codes mentioned: Wrench light (powertrain fault indicator), Check Engine Light, Traction Control warning
Repairs/costs cited: Throttle body cleaning, replacement, or ECM/PCM reprogramming. Some owners report replacing throttle body twice without resolution. One owner spent over $1,000 on alternator, belts, and camshaft before identifying throttle body as the issue. Dealers and Ford recommend cleaning and reprogramming first.
Recalls/TSBs owners mention: No recall. Ford service has stated wrench light presence indicates throttle body issue. One dealership cleaned throttle body and reprogrammed PCM; another added fuel injector flush and throttle body cleaning.
Evaporator discharge air temperature (EATC) sensor failure
AC climate control temperature sensor fails to register actual cabin temperature, causing the AC compressor to shut off. System blows only warm or hot air, creating fogging and visibility hazards. Sensor gives false readings (thinks it's ice-cold when outdoor temps exceed 100°F), preventing the compressor from engaging even when AC is needed.
When: Reported on relatively low-mileage vehicles (one at 30,000 miles implied by recent purchase)
Symptoms owners cite: AC compressor fails to turn on; System blows only warm/hot air; Windshield fogs up, creating visibility hazard; Passenger compartment does not cool; Sensor reads incorrectly (displays ice-cold in hot weather); Erratic temperature fluctuations; Cannot defog windshield
Repairs/costs cited: EATC sensor replacement required. Cost not specified in narratives. One owner notes this is a known issue Ford is aware of.
Recalls/TSBs owners mention: Owners report Ford is 'well aware' of faulty EATC sensors but have not issued a recall or service bulletin.
Cruise control button failure
Cruise control buttons malfunction, causing incorrect or reversed function. Resume button stops working. Buttons that should decrease speed instead increase it, creating a safety hazard if driver accidentally activates them while trying to slow the vehicle.
When: Not specified in complaint
Symptoms owners cite: Resume cruise button inoperative; +SET button functions as resume instead of set/increase; -SET button functions as set/increase instead of decrease; ON/OFF buttons only work intermittently; Reversed function (deceleration button speeds car up)
Bearing failure due to oil system inadequacy
Engine bearings fail prematurely, requiring engine replacement. In one case, low oil level due to filter leak was not detected adequately by the warning system. Check engine light never illuminated; oil light only flashed briefly twice. Dealer diagnosed the need for a complete engine replacement.
When: Approximately 30,000 miles
Symptoms owners cite: Oil light flashes briefly then goes out; Check engine light never illuminates; Oil level too low (filter leak source); Engine bearing failure requiring full replacement
Repairs/costs cited: Complete engine replacement. Not covered by warranty due to lack of oil change receipts. Owner states warranty denial occurred despite low-mileage vehicle.
Recalls/TSBs owners mention: Warranty denied due to missing oil change documentation.
