Should I buy a 2007 Ford Mustang with documented fuel system problems?

Depends on the price and the specific vehicle. Documented fuel system issues should be priced into the purchase — if the seller is asking full retail, negotiate down by the expected repair cost. A pre-purchase inspection from an independent shop tells you whether THIS specific vehicle has already shown the symptoms or not.

What stands out

Among the 9 model years of Ford Mustang in our records for fuel system problems, this one ranks #3 by owner-complaint volume.

No new NHTSA fuel system complaint has been filed on this vehicle in over 16 years — the issue may be aging out of the active population.

The failure pattern owners describe

Fuel tank filling is the dominant complaint in these narratives. Owners across the country report that the pump nozzle cutoff sensor triggers prematurely—usually at 1/3 to 1/2 tank—forcing them to pump in short bursts to get closer to full capacity. The pump clicks as if the tank is full when it clearly is not. Attempts to pump more fuel cause repeated cutoffs every few seconds. Removing the nozzle causes gasoline to splash back onto the owner and vehicle.

Owners note the problem is inconsistent: sometimes it occurs every fillup, other times intermittently. The behavior varies by gas station and even pump direction or nozzle angle—one owner discovered the car filled normally when parked facing into the wind but not when facing away. Dealers have been unable to diagnose or repair the issue; some stated they found nothing wrong and suggested owners try different stations or pumps without vapor recovery sensors. Ford issued a TSB related to a 2005 model but no formal recall. One dealer mentioned the fuel tank has two sections that may not transfer fuel between them.

Separate from refueling, several owners report sudden unintended acceleration—the engine revs to full throttle while the vehicle is stopped or moving slowly, overriding the brake pedal. These incidents occur without warning and are not reproducible on demand. One resulted in a crash. Engine stalls, fuel throttle failures, and persistent check engine lights from evaporative leaks round out the fuel-system-related complaints, with dealers unable to provide lasting fixes.

Failure modes owners describe

Fuel tank overfill shutoff—premature cutoff

The fuel pump nozzle cutoff sensor triggers early, stopping fuel flow well before the tank is full. Owners report the pump clicking off at 1/3 to 1/2 tank capacity, forcing them to pump in multiple short bursts. Attempts to continue filling cause the pump to click off repeatedly. The tank gauge shows well below full, yet the sensor prevents further fueling.

When: Early in ownership; reported from 2,308 miles through 54,000 miles on various vehicles.

Symptoms owners cite: Pump clicks off prematurely, stopping flow at 1/3 to 1/2 tank; Pump clicks off intermittently on every attempt to continue fueling; Fuel gauge shows tank not full when pump cuts off; Cannot achieve full tank capacity regardless of station or technique; Gasoline backs up and splashes when nozzle is removed; Problem occurs inconsistently—sometimes at same station, sometimes varies by pump direction/angle

Codes mentioned: NHTSA Campaign ID 10014651 (fuel system, other)

Repairs/costs cited: One owner had fuel system rebuilt by local mechanic with no resolution. Another dealer diagnosed a two-part fuel tank that was not transferring gas between sections. Another dealer stated fuel tank replacement was needed. Many dealers found no fault and offered no repair.

Recalls/TSBs owners mention: Ford issued a Technical Service Bulletin (TSB) for 2005 model year related to NHTSA Campaign 10014651. Dealers instructed owners to try different gas stations, use pump nozzles without sensors, angle the nozzle to 2 o'clock position, or face the vehicle into the wind. Ford told some owners the vehicle must continue fueling as needed until a remedy is found. No recall issued.

Unintended acceleration—sudden full throttle while stopped

Engine suddenly revs to full throttle while the vehicle is stopped or moving slowly, with the driver's foot on the brake. The vehicle lurches forward forcefully, overriding braking effort. Occurs without warning and is not reproducible on demand. Turning off the ignition resets the condition.

When: While stopped in traffic or parked with engine running; reported at low mileage (5,075 miles on one vehicle). Occurs 2–3 times per day on one owner's car.

Symptoms owners cite: Engine suddenly goes to full throttle while vehicle is stopped; Vehicle lunges forward with rear tires spinning despite brake pedal held down; Occurs without warning and is not reproducible on demand; Turning off ignition stops the condition; Happens with some regularity, approximately 2–3 times per day in one case; In one case, caused vehicle to accelerate suddenly from parked position, crashing into adjacent vehicle and wall

Repairs/costs cited: One owner reported the dealer found the fuel throttle had failed. Other dealers were unable to diagnose the root cause across three visits. Repairs were not completed.

Recalls/TSBs owners mention: Ford dealership offered to investigate the condition at owner expense with no assurance of repair. No recall or service bulletin mentioned.

Evaporative emission system—persistent check engine light

Check engine light illuminates repeatedly, triggered by a very small evaporative leak the emissions system cannot locate. The light comes on at random intervals and has been cleared multiple times without permanent resolution. The dealer reports the system is too sensitive and cannot pinpoint the leak.

When: Began the day after purchase; recurred multiple times over several months.

Symptoms owners cite: Check engine light illuminates at random times; Light comes on after purchase and recurs 3+ times; Dealer unable to locate small evaporative leak despite scanning equipment

Codes mentioned: Evaporative emission leak code (specific code not stated)

Repairs/costs cited: Dealer scanned system multiple times and cleared the light repeatedly without identifying the leak source. No permanent repair offered.

Recalls/TSBs owners mention: Ford Motor Company stated the system is too sensitive and they cannot find a permanent fix. Owners were advised to continue clearing the light as it returns.

Engine stall—vehicle shuts off without warning

Engine shuts off suddenly while driving without any warning or apparent cause. The vehicle was taken to the dealer multiple times but no consistent cause was identified on the first two visits.

When: At 2,308 miles (failure mileage); vehicle back in dealer three times as of June 28, 2007.

Symptoms owners cite: Vehicle shuts off without warning while driving

Repairs/costs cited: First dealer visit found no failures. Second visit: dealer stated fuel throttle had failed. Third visit: dealer unable to determine cause of failure.

Recalls/TSBs owners mention: No recall or service bulletin mentioned in this report.

A quarter of owners report trouble before 5,000; a quarter make it past 62,000. 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?
