The failure pattern owners describe
The 2005 Taurus shows a persistent unintended-acceleration problem across multiple complaints. Owners report the vehicle holding or increasing speed without any throttle input—sometimes maintaining 30–70 mph on the highway with foot completely off the pedal, or revving to 4,500 rpm at a standstill. Braking slows it temporarily, but acceleration resumes. Pumping the gas pedal, shifting to neutral, or shutting off the engine can interrupt the issue, though it's intermittent enough that one owner had no recurrence over two years. One owner found a disconnected throttle-control cable; Ford dealers have found nothing to repair on multiple visits. No recall exists for this problem.
Flex-fuel models and standard Taurus models both suffer from fuel-gauge failures. The gauge needle sticks at 7/8 or 3/4 tank regardless of actual level, or doesn't move at all, preventing accurate fuel monitoring. One flex-fuel owner with check-engine light issues resolved the problem with a $50 flex-fuel module replacement under the dash (part #YF1U-14A069AA)—confirming the tank sending unit wasn't at fault. Other owners received repair estimates over $1,000, with multiple independent shops unfamiliar with the fix. One flex-fuel owner missed an undelivered recall (06N07 7807, PCM recalibration) and found dealerships refused to service it after the deadline passed.
Failure modes owners describe
Unintended acceleration
Vehicle accelerates without driver input, typically occurring during highway driving or in warmer months. Symptoms include engine maintaining or increasing speed while foot is completely off accelerator, reaching speeds of 30–70 mph without pedal contact. Braking temporarily slows the car, but it resumes acceleration. Turning off the engine and restarting, or pumping the accelerator pedal, may temporarily resolve the issue. One owner reported finding a disconnected throttle-control cable.
When: Highway driving, warmer months; intermittent, with some incidents separated by 2+ years
Symptoms owners cite: Vehicle maintains 30–70 mph without driver touching accelerator; Engine revs up to 4500 rpm without pedal input; Brakes slow car temporarily, but acceleration resumes; Pumping accelerator pedal may temporarily stop the behavior; Putting vehicle in neutral stops acceleration; Turning engine off and restarting may temporarily resolve issue; Engine racing even after shutdown and restart; Throttle-control cable found disconnected (one instance)
Repairs/costs cited: One owner self-repaired by reconnecting a loose throttle-control cable
Recalls/TSBs owners mention: Ford dealer stated no recall exists for this issue at time of complaint
Erratic fuel gauge
Fuel gauge does not accurately reflect actual fuel level in tank. Needle reads higher than actual fuel remaining (typically 7/8 or 3/4 tank when nearly full), or remains unreadable entirely. One flex-fuel model owner noted engine check light illuminated after gauge showed empty. One documented repair involved replacement of a flex-fuel module under the dash (part #YF1U-14A069AA, $50 at dealer); owner confirmed the fuel sending unit in tank was not the problem.
When: Ongoing; reported across multiple model years and trim levels
Symptoms owners cite: Fuel gauge needle stuck at 7/8 or 3/4 tank regardless of actual level; Gauge does not register when tank is full; Gauge unreadable (no needle movement); Engine check light illuminated (flex-fuel models); Inspection failure due to check engine light (New York State)
Repairs/costs cited: One flex-fuel model: replaced flex-fuel module under dash (part #YF1U-14A069AA) for $50 at dealer; one unrepaired estimate quoted over $1,000; multiple shops unfamiliar with diagnosis
Missed flex-fuel PCM recall
2005 Taurus flex-fuel models subject to recall 06N07 7807 (PCM recalibration for flex-fuel) that owner did not receive notice for despite stable address since 1984. Two separate Ford dealerships performed service without addressing recall. One dealership refused service, citing missed deadline. Owner reports intermittent starting problems with E85 fuel.
When: Recall issued; complaint filed August 2015
Symptoms owners cite: Intermittent starting problems with E85 fuel; No recall notice received at registered address; Dealerships failed to perform recall during routine service
Recalls/TSBs owners mention: Recall 06N07 7807 for PCM recalibration (flex-fuel); dealership claimed deadline for repair had passed and refused service
Rough deceleration
Vehicle decelerates roughly when slowing to a stop, particularly at red lights and stop signs. One owner reports this occurs concurrently with unintended acceleration issues.
When: During deceleration to full stop
Symptoms owners cite: Rough, jerky deceleration approaching zero speed at traffic lights and stop signs

Common questions
How serious is the fuel system problem on the 2005 Ford Taurus?
It's a documented issue but not catastrophic. 11 complaints have been filed. Repairs average $1,200 and most owners catch it before it causes a breakdown.
At what mileage does the fuel system typically fail?
Across the 8 complaints that reported odometer mileage, most fuel system failures cluster between 73,443 and 155,000 miles, with the median around 100,000. A quarter of owners report trouble before 73,443; a quarter make it past 155,000. 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 $1,200 for fuel system 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 fuel system?
No active recalls currently cover fuel system 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.
