Owners of 2015 Ford Taurus vehicles report fuel pump and fuel pump module failures as the dominant complaint—the vehicle stalls without warning while driving or refuses to start when parked, sometimes after multiple restart attempts. Failures occur across the mileage spectrum, from around 16,800 to 140,000 miles. Many owners cite NHTSA Campaign 16V621000 (turbo fuel pump module recall) but state their VINs are not included despite experiencing identical symptoms. One owner with a non-turbo 3.5L V6 engine explicitly notes Ford's recall excludes his engine type, yet his vehicle failed identically to turbo models.
A smaller number report fuel line leaks causing odor and frequent refueling, or throttle body actuator failure causing violent shaking and stall at lower mileage. One owner mentions auxiliary battery wiring harness deterioration discovered at 140,000 miles.
Diagnostic results vary: fuel pump failure (DTC P0627 cited once), fuel pump module defect, and fuel pump modulator overheating. Some owners self-repaired; others used dealers or independent shops. Many report the vehicle stalls mid-drive at low speeds (5–44 MPH), forcing roadside stops or towing. Several attempts to restart are common. No warning lights illuminate in many cases. Owners report frustration when manufacturers confirm their VINs fall outside existing recall boundaries despite matching failure signatures.
Failure modes owners describe
Fuel Pump or Fuel Pump Module Failure
The fuel pump or fuel pump module fails, preventing fuel delivery to the engine. This is the most commonly reported failure across the complaint set. Multiple owners report the vehicle suddenly losing fuel delivery while driving or failing to start. Many complaints reference NHTSA Campaign 16V621000, which covers fuel pump modules on turbo models, yet several non-turbo 3.5L V6 owners report the same failure.
When: Occurs between 16,823 and 140,000 miles; many failures occur while driving at various speeds (5 to 44 MPH reported), though some occur when parked.
Symptoms owners cite: Vehicle stalls without warning while driving; Vehicle fails to start despite multiple attempts; No fuel reaching the engine; Occasionally accompanied by jerking or shuddering before stall; No warning light illuminated in many cases
Codes mentioned: P0627 (Fuel Pump Failure)
Repairs/costs cited: Fuel pump or fuel pump module replacement. One owner reported a fuel pump modulator also required replacement due to overheating the fuel pump. Some owners self-replaced the fuel pump module or electric module; others used dealers or independent mechanics. Costs not specified in narratives.
Recalls/TSBs owners mention: NHTSA Campaign 16V621000 (Fuel System, Gasoline) covers turbo-charged 2013–2015 Taurus models. Multiple owners report their VINs were not included in the recall despite experiencing the same failure. Campaign 16S31 also mentioned. Manufacturer informed several owners their vehicles were not under recall.
Fuel Line Leak
A fuel line develops a leak, causing fuel odor and requiring frequent refueling. One complaint details a fuel line that had been temporarily repaired and subsequently failed again.
When: Failure mileage approximately 127,424 miles.
Symptoms owners cite: Fuel line leaking; Fuel odor emanating from vehicle; Frequent refueling required; Fuel indicator warning illuminating while idle; Discrepancy between fuel gauge and remaining distance estimate
Repairs/costs cited: Fuel line replaced. Previous repair noted as temporary fix that did not hold.
Throttle Body Actuator Failure
The throttle body actuator fails, causing the vehicle to shake violently and stall. This occurs at lower mileage and is distinct from fuel pump failures, though it produces similar stalling symptoms.
When: Failure mileage approximately 38,000 miles.
Symptoms owners cite: Service vehicle soon warning light illuminates; Vehicle violently shakes; Vehicle stalls; Engine runs after restart
Repairs/costs cited: Throttle body actuator replaced by dealer.
Auxiliary Battery Wiring Harness Failure
The auxiliary battery wiring harness deteriorates and requires replacement. This was identified by a dealer during routine service but was not addressed as part of any known recall or repair campaign.
When: Failure mileage approximately 140,000 miles.
Symptoms owners cite: No warning light illuminated; Wiring harness failing
Repairs/costs cited: Wiring harness replacement recommended by dealer but not performed per narrative. Vehicle also had prior fuel pump and fuel tank mounting bolt replacements.
