What stands out
Owners have filed 42 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.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical 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.
FORD: IF THERE IS AN INTERMITTENT LACK OF POWER, SURGE, OR HESITATION WHILE DRIVING THE BRAKES WILL OVERRIDE ACCELERATION.

The failure pattern owners describe
The 2007 Fusion electrical system is plagued by multiple distinct failures that create real safety risks. The PCM (powertrain control module) is the worst offender: it fails without warning, causing instant engine stall on highways, and often takes out all six ignition coils and spark plugs in the process. Owners paid $800–$2,000 to fix this, and Ford's 3-year/36,000-mile PCM warranty often leaves owners unprotected after 60,000+ miles.
Battery cables corrode aggressively, even on low-mileage vehicles in non-salt areas. The corrosion extends 20+ feet along wiring harnesses, destroying cable sheaths and preventing starting. This happens as early as 12 months into ownership at fewer than 30,000 miles, sometimes just beyond the 36,000-mile warranty cutoff, leaving owners on the hook for $400+ repairs.
Turn signal failures are silent and dangerous: the smart junction box fails internally, but the dash gives no warning that the signal isn't working. Repair cost is $600 per junction box.
Door latches fail across all four doors, sometimes popping out on their own. Doors won't lock, won't open from inside, or become completely stuck. The driver's door lock can jam in the locked position despite pressing the unlock button.
Keys get stuck in the ignition on many examples, a defect Ford has known about since 2003 but never recalled. Steering wheel locks simultaneously in some cases. Removing a stuck key costs $400+.
Other owners reported A/C compressor burnout from overpressurization, brake pedal requiring full-floor travel to stop, and in two cases, complete electrical fires that destroyed the vehicle.

Failure modes owners describe
PCM (Powertrain Control Module) Failure
Engine control module fails, causing loss of engine power, stalling, and damage to ignition coils and spark plugs. Multiple reports indicate the PCM overheats or shorts internally, sometimes burning coil packs on cylinder #4. Owners report near-immediate stalling after failure, with no safe limp-home capability.
When: Between 60,000 and 160,000 miles; one case at 28,000 miles
Symptoms owners cite: Complete loss of engine power while driving; Vehicle stalls or won't restart; Ignition coils burnt, melted, or damaged; Spark plugs melted or damaged; Orange wrench warning icon on dash; Engine fire risk (reported in one case); RPM instability
Codes mentioned: P0491, P2110
Repairs/costs cited: PCM replacement, ignition coil pack replacement (all six), spark plug replacement, computer reprogramming. Costs reported: $800–$2,000 plus labor. Part availability issues; national backorder reported.
Recalls/TSBs owners mention: Ford issued a bulletin acknowledging a known issue with the PCM on 2007 Fusion. PCM warranty: 3 years/36,000 miles (often exceeded before failure occurs). ECU warranty: 8 years/80,000 miles, but Ford distinguishes between the two when assessing coverage.
Battery Cable Corrosion
Battery cables and posts corrode excessively, even on low-mileage vehicles in non-salt environments. Corrosion extends 20+ feet along cable runs, destroying insulation sheaths and preventing engine start. Occurs within first year to early ownership on some vehicles.
When: As early as 12 months; reported at 29,055 miles, 42,000 miles, and 48,000 miles
Symptoms owners cite: Vehicle will not start; Battery corrosion visible on posts and connectors; Severe corrosion along cable runs; Multiple startup failures; Dashboard warning lights (oil light, airbag light) illuminate before stalling
Repairs/costs cited: Battery replacement, battery cable replacement (sometimes up to 20 feet of wiring), connector replacement. One dealer replaced cables and battery for free (under warranty); others charged $428. Dealership initially misdiagnosed as battery issue only, missing underlying cable defect.
Recalls/TSBs owners mention: No TSB issued. No warranty extension offered. Failures occurring just over 36,000-mile warranty cutoff left owners unprotected. Ford declined to cover repair costs despite quality control nature of the defect.
Smart Junction Box Failure (Turn Signal)
Turn signals fail silently with no warning to driver. Bulb and fuse test fine; the smart junction box module internally fails. Driver has no dash indication that signal is inoperative, creating a safety blind spot.
When: No specific mileage reported; detected during routine maintenance
Symptoms owners cite: Turn signal does not illuminate externally; No warning indicator on dashboard (signal bulb fast-flash); Bulb and fuse test good; Dimly flashing or steady illumination instead of normal blink
Repairs/costs cited: Smart junction box replacement. Cost: $600 per unit.
Recalls/TSBs owners mention: No recall issued. Ford dealers confirm diagnosis and quote repair cost. Owners report this is a common problem online with no manufacturer action.
Ignition Key Stuck in Ignition
Key becomes stuck and cannot be removed from ignition cylinder. Shifter knob assembly or internal ignition mechanism binding. Leaves vehicle unattended with keys accessible, creating theft risk.
When: Not mileage-specific; documented as recurring issue since 2003 model year
Symptoms owners cite: Key will not remove from ignition; Occasional freeing after repeated attempts or shifter manipulation; Steering wheel may lock randomly; Shifter may not lock fully into park initially
Repairs/costs cited: Shifter knob assembly replacement or ignition cylinder service. Cost: $438 reported; one owner paid twice in two weeks for same issue.
Recalls/TSBs owners mention: No recall issued despite Ford knowledge of issue since 2003. Ford customer relations reported indifferent to complaints ('like an oh well'). Issue documented across Focus and Fusion forums.
Door Latch Failure (All Doors)
Front and rear door latches fail, allowing doors to pop open or remain stuck. Passenger-side door often won't lock. Doors may open only from outside. Safety concern if fire or emergency occurs.
When: Reported across entire ownership period; some cases in first year
Symptoms owners cite: Door latch pops out of place; Door cannot be opened from inside; Door will not lock; Multiple doors fail sequentially (front, then rear)
Repairs/costs cited: Door latch replacement. Owner in narrative #1 could only afford one driver-side repair, leaving other doors inoperable.
Recalls/TSBs owners mention: No specific manufacturer response or recall noted for latch failures.
