What stands out
Owners have filed 35 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.
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 2007 Fusion's engine systems have generated consistent complaints across multiple failure modes. The most common issue is the idler/tensioner pulley bolt: it snaps or tears, causing the serpentine belt to slip or detach. Owners report this happens repeatedly even after dealership replacement, sometimes within months. When the belt comes off, you lose power steering and the alternator stops charging—dangerous situations at highway speeds. One owner spent over $1,600 on repeated fixes; another had the entire engine pulled just to extract a stuck bolt. Dealerships have offered no warranty coverage or recalls.
Throttle response is unpredictable. Owners describe 1-5 second delays between flooring the pedal and engine response, making merging and hill driving risky. Some say the car enters a "hold" mode that won't accelerate until the pedal is pushed very far down, then surges uncontrollably.
Engine stalling happens unexpectedly at various speeds, sometimes triggered by braking. A wrench light comes on, the car limps along at reduced speed, and restarting clears it—but the problem recurs unpredictably over months or years. Ignition coils fail, PCMs burn out from coil damage, and one owner's computer sent too much fuel to the cylinders. Repairs often don't stick.
Oil consumption is excessive on some units, and one engine seized from oil pump failure with no warning light. Catalytic converters fail, and idle RPM hangs high on cold starts, making it difficult to control stopping.

Failure modes owners describe
Idler/Tensioner Pulley Bolt Failure
The idler pulley bolt snaps, fractures, or tears, causing the serpentine belt to slip or fall off. Owners report the bolt snapping cleanly or fraying at the end. Repeated failures occur even after replacement at dealerships. Loss of power steering and alternator charging results from belt detachment.
When: Between 49k and 134k miles; some failures within months of prior replacement; one case reported 4 occurrences since 2008
Symptoms owners cite: Loud squeaking or squealing from engine at startup or under acceleration; Bolt snapped or leaning to the side; Serpentine belt falls off or marks on belt from rubbing; Loss of power steering; Battery warning light illuminated; Alternator stops charging
Repairs/costs cited: Idler pulley and/or tensioner pulley replaced multiple times; one case involved complete engine removal to extract stuck bolt; costs cited as $200 per replacement, over $1,600 total for repeated failures
Recalls/TSBs owners mention: Dealer stated no warranty coverage; no recall remedy provided; manufacturer made aware but offered no assistance; one case mentioned service bulletin exists but only covers in-warranty vehicles
Throttle Response Delay / Hesitation
Excessive delay between accelerator input and engine response, particularly during hill backing, merging, or light speed changes. Throttle becomes unresponsive for 1-5 seconds even with pedal to the floor. Vehicle enters a 'hold' mode that prevents normal acceleration.
When: Occurs intermittently during various driving conditions; no specific mileage noted
Symptoms owners cite: Delayed throttle response of 1-5 seconds after pedal input; Vehicle unresponsive to accelerator pedal until very high pedal travel; Jerking while driving; Vehicle enters 'hold' mode where it does not respond to accelerator; Speed does not change despite floored accelerator pedal
Repairs/costs cited: One owner reports throttle cleaned by dealership without fixing issue; most complaints do not cite repairs performed
Recalls/TSBs owners mention: Dealership unable to recreate problem; owner found evidence of similar issues in 2009-2011 Fusions under recall that excludes 2007 models
Stalling and Loss of Power
Engine stalls unexpectedly while driving at various speeds (30-70 mph), sometimes during braking or at traffic lights. Vehicle enters limp mode with wrench light illuminated. Stall can be resolved by restarting, but recurs unpredictably.
When: Between 24k and 134k miles; recurs over months or years
Symptoms owners cite: Engine stalls without warning while driving; Wrench symbol or check engine light illuminates; Vehicle enters limp mode; Loss of power during acceleration; Stalling during hard braking; Vehicle decelerates to 21 mph or similar speed limitation
Repairs/costs cited: Starter replaced; TCM (transmission control module) replaced; throttle cleaned; coil packs and spark plugs replaced; PCM replaced; catalytic converter replaced; one case involved engine and computer replacement totaling $2,200; repairs often do not resolve issue
Recalls/TSBs owners mention: Dealership unable to recreate problem or offered no customer satisfaction program; no recall for 2007 model; service bulletin exists but limited to warranty coverage; manufacturer offered no assistance in multiple cases
Ignition Coil and PCM Failure
Individual ignition coils fail, causing cylinder misfires and triggering check engine light. Failed coils can burn out the PCM (powertrain control module). Coil failures lead to stalling, jerking, and rough running.
When: Between 49k and 90k miles
Symptoms owners cite: Check engine light illuminated; Jerking while driving; Engine hesitation; Vehicle stalls; Loud noise from engine; Violent jerking while driving
Codes mentioned: Cylinder 5 coil failure, Cylinder 6 coil failure
Repairs/costs cited: Coil packs replaced (one case all six coils); spark plugs replaced; PCM replaced; one case initially misdiagnosed as coil failure but later found to be computer sending too much fuel; engine and computer replacement in one case
Recalls/TSBs owners mention: Manufacturer made aware but offered no assistance; no recall remedy provided
Fuel Management / Over-Fueling
Computer sends excessive fuel to cylinders, causing rich running condition. Owner reported this after initial misdiagnosis of coil failure.
When: At 49,582 miles in one reported case
Symptoms owners cite: Loud noise from engine; Violent jerking; Engine stalls
Repairs/costs cited: Engine and computer replaced
Throttle Body Malfunction
Throttle body fails to function, causing loss of power and inability to accelerate despite driver input.
When: At 131,157 miles
Symptoms owners cite: Speed decreases while driving 70 mph; Failure to accelerate; Check engine light and wrench indicator illuminated
Repairs/costs cited: Throttle body replacement needed
Recalls/TSBs owners mention: Manufacturer notified of failure; no assistance provided
Idle Speed / RPM Hang
Engine idles at elevated RPM (1500-2000) on cold start and holds high RPM for extended periods during gear shifts. Difficult to control vehicle speed; engine fights brakes.
When: Cold start conditions; occurs on automatic transmission models
Symptoms owners cite: RPM stays at 1500-2000 on cold start; Transmission holds high RPM for prolonged periods during shift; Difficult to slow vehicle at stops; Engine fights the brakes
Repairs/costs cited: Owner showed dealership TSB (technical service bulletin) but dealer disregarded it; no repairs cited as successful
Recalls/TSBs owners mention: Dealership not receptive to technical service bulletin regarding RPM issue
Excessive Oil Consumption
Engine consumes oil at an abnormal rate. One new vehicle with only 1,700 miles already showed oil consumption issue.
When: Early in vehicle life; one case at 1,700 miles
Symptoms owners cite: Oil level drops despite regular oil changes
Repairs/costs cited: Dealer monitored oil consumption but did not correct underlying issue
Oil Pump Failure
Oil pump fails internally, causing sudden engine seizure. No warning light precedes failure.
When: Occurs without specific mileage noted; happens during startup in one case
Symptoms owners cite: Engine knocking as if low on oil despite adequate level; No engine light warning; Engine will not restart; Engine has seized
Repairs/costs cited: Engine blown; oil pump failure identified
Catalytic Converter Failure
Catalytic converter fails, triggering check engine light. Part shortages reported from vendor prevent timely replacement.
When: Specific mileage not cited
Symptoms owners cite: Check engine light illuminated; Bad emissions being produced
Repairs/costs cited: Catalytic converter replacement needed; vendor unable to supply part; owner waiting on part with no ETA
Uncontrolled Engine Revving
Engine revs on its own without driver input, requiring sudden braking to control speed.
When: City driving; occurs intermittently
Symptoms owners cite: Engine starts revving uncontrollably at 25 mph; Requires sudden braking to stop

Common questions
How serious is the engine problem on the 2007 Ford Fusion?
It's a documented issue but not catastrophic. 35 complaints have been filed. Repairs average $3,100 and most owners catch it before it causes a breakdown.
At what mileage does the engine typically fail?
Across the 27 complaints that reported odometer mileage, most engine failures cluster between 58,100 and 131,157 miles, with the median around 82,000. A quarter of owners report trouble before 58,100; a quarter make it past 131,157. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $3,100 for engine repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to engine?
No active recalls currently cover engine issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
