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.

What stands out
Owners have filed 25 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.
No new NHTSA engine complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
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 failure pattern owners describe
Unintended acceleration is the most persistent complaint. Owners describe accelerator pedals that stick or refuse to return to idle, causing vehicles to rev to 4000–5000 RPM without driver input. One owner's pedal was physically loose with no tension to hold it up. The problem strikes at stop signs, on freeway ramps, and during normal driving—sometimes 4–5 times per 20-mile trip. Brakes override the condition but require maximum force, and shifting into Park produces loud explosive sounds.
Stalling at idle occurs without warning, often at red lights, especially under air-conditioning load. The engine lurches forward as if fighting to stay alive, then may die completely. No check engine codes appear afterward.
Multiple owners report sudden electrical shutdown—all dashboard power and lights cut out while driving at speed. The vehicle stops completely and may or may not restart. Dealers have replaced fuel pumps, modules, processors, and batteries without resolving the problem, then claim they cannot duplicate it.
Two vehicles caught fire under the hood: one at 70 mph with warning lights lit, the other while parked. One 2006 Taurus owner points to a structural flaw—the oil filter sits directly above the starter solenoid, where leaked oil can ignite on hot electrical components. Ford dealers allegedly agreed this is a design problem but no recall followed.
A transmission fluid leak has been documented, with the transaxle vent prematurely fracturing and draining fluid into the motor when shut down. Starting failures occur in cold weather with theft-light warnings.

Failure modes owners describe
Unintended acceleration / stuck accelerator pedal
Engine revs and vehicle accelerates without driver input. Pedal physically sticks or returns slowly to idle after release. Happens intermittently on startup, during driving, or at stops. Brakes can override but require maximum force. Some owners report loose pedal with no tension to hold it up.
When: Intermittent, occurs 4–5 times per 20-mile trip on some vehicles; worse on freeway ramps and at stop signs; ranges from 50,000 to 95,000+ miles
Symptoms owners cite: Vehicle accelerates without pedal input; Accelerator pedal sticks or does not return to idle; Engine revs to 4000–5000 RPM in Park; Loose or depressed gas pedal with no tension; Requires hard brake pressure to slow or stop; Loud explosive sound when shifting into Park
Repairs/costs cited: No repair solutions documented in narratives; owners adapted by punching accelerator to unstick it or using it as makeshift cruise control
Engine stalling at idle and rough idle
Engine dies at red lights or while stopped. Vehicle lurches forward with brakes applied as if revving to stay running. Rough idle, especially under load (air conditioning) or after extended driving. Some restarts immediately; other episodes produce no diagnostic codes.
When: Multiple instances over months; occurs 6+ times in 2-month period on one vehicle; mileage range 78,000–125,000
Symptoms owners cite: Engine stalls at stop lights without warning; Rough idle condition; Forward lurching while brake applied; RPM drop when brakes applied; Vehicle may not restart immediately; No check engine codes present after event
Repairs/costs cited: Dealers unable to reproduce issue; no successful repairs documented
Complete electrical shutdown while driving
All power and lights cut off suddenly during operation. Vehicle may restart after a few minutes or require tow. Instrument panel lights flash before shutdown. Occurs sporadically and unpredictably. Dealers replaced fuel pump and fuel pump module; processor and battery also replaced; problem persists.
When: Between 65,000 and 70,000 miles; happens 4+ times; continues after repairs
Symptoms owners cite: All dashboard lights and power shut off suddenly; Vehicle completely stops; Instrument panel lights flash before shutdown; Speedometer may drop to zero and reappear; Vehicle may restart or may not
Repairs/costs cited: Fuel pump replaced; fuel pump module replaced; processor replaced; battery replaced—problem unresolved
Check engine light illumination and dealer avoidance of diagnostics
Check engine warning light comes on after purchase; dealer resets it without proper diagnosis. When light reoccurs, dealer disengages the check engine fuse rather than perform full diagnostic. Owner concerned about loss of future warning signals for engine failure.
When: Shortly after used-car purchase; approximately 69,000 miles
Symptoms owners cite: Check engine warning light illuminates; Light resets temporarily but returns; Spark plugs contaminated by water (dealer observation)
Repairs/costs cited: Dealer recommended spark plug replacement but owner declined; proper diagnostic refused
Recalls/TSBs owners mention: Dealer disabled check engine fuse instead of addressing underlying issue
Engine fire under hood
Engine ignites into flames while driving or while parked unoccupied. One incident occurred at 70 mph with check engine and oil warning lights illuminated just before fire. Another incident occurred while parked. Both vehicles completely burned.
When: At 158,000 miles (one vehicle); at 180,000 miles (parked vehicle)
Symptoms owners cite: Flames under hood; Check engine and oil warning lights illuminated (one incident); Complete vehicle fire
Repairs/costs cited: One vehicle towed to independent mechanic but not diagnosed or repaired; second vehicle not inspected
Oil filter design and fire risk (structural complaint)
Oil filter location directly above starter and solenoid assembly creates risk of oil leakage onto hot electrical components, potentially causing fire. Owner reports Ford dealers in Denver agreed this is a design flaw but no recall or public notice issued.
When: Design flaw on 3.0L engine; mileage not specified
Symptoms owners cite: Oil filter positioned above starter solenoid; Potential for oil leak onto electrical components
Repairs/costs cited: No repairs offered; reported as design issue
Recalls/TSBs owners mention: No recall or public notification despite dealer acknowledgment of design flaw
Transmission fluid leak into engine
Transmission fluid leaks from front of vehicle and drains into motor when engine shut off. Transaxle vent and 90-degree vent stem prematurely fractured, causing the leak.
When: At 140,000 miles
Symptoms owners cite: Transmission fluid leak under front of vehicle; Fluid enters motor when vehicle turned off
Repairs/costs cited: Requires replacement of transaxle vent and 90-degree vent stem with clamps; vehicle not repaired per narrative
Recalls/TSBs owners mention: Manufacturer notified but no further action documented
Catalytic converter detachment
Catalytic converter fell off vehicle during normal operation.
When: Between 58,531 and 63,000 miles
Symptoms owners cite: Catalytic converter separated from vehicle
Repairs/costs cited: Repaired by local mechanic
Recalls/TSBs owners mention: Manufacturer notified but no further assistance provided
Starting failure in cold temperatures
Vehicle will not start in extremely cold conditions. Theft light illuminates when vehicle stalls.
When: At 125,000 miles during cold weather
Symptoms owners cite: No-start condition in extreme cold; Theft warning light illuminates upon stall
Repairs/costs cited: Vehicle not diagnosed by dealer; no repairs made
Recalls/TSBs owners mention: No recalls identified
Idle and acceleration issues—undiagnosed
General idle and acceleration problems that persist despite multiple repair attempts. Mechanics unable to confirm root cause. Related to seat belt tensioner lockup issue on same vehicle.
When: Mileage not specified
Symptoms owners cite: Idle issues; Acceleration problems
Repairs/costs cited: Multiple repairs attempted; cause not identified
