Among the 12 model years of Ford Explorer in our records for fuel system problems, this one ranks #3 by owner-complaint volume.
The failure pattern owners describe
Buyer takeaway: The 2006 Explorer has serious fuel-system design issues: EVAP canisters fail repeatedly, making refueling dangerous (fuel sprays back on driver), and fuel tanks can leak without impact damage. Multiple repairs often don't stick, and dealers may deny warranty coverage.
Fuel-system troubles dominate these 2006 Explorer complaints. The most common issue is EVAP canister failure, documented in a TSB (07-25-3) that Ford acknowledges but has not recalled. Owners cannot fill the tank normally—the pump kicks off every half-gallon to few gallons, and fuel backs up and sprays out the filler neck onto the driver and ground. Fill times stretch to 10–45 minutes. Some owners smell bubbling in the fuel lines and hear it gurgling. This defect has recurred within months or years even after dealer repair.
Fuel tanks also leak from underneath without obvious impact, creating heavy gasoline odor and fire risk. One owner's dealership blamed road debris and denied warranty, though an insurance adjuster noted the vehicle had no protective skid plate.
Fuel-sending units, fill valves, and fuel rails fail as well, either preventing fuel entry or causing overflow. One dealer acknowledged the fill problem "happens all the time," yet no recall exists. Owners cite repair costs of $400+ for canister and hose replacement, sometimes needing multiple trips to different dealers. Several note the issue recurred after repair, and one was charged a deductible the second time around because 12 months had passed since the first fix.

Failure modes owners describe
Fuel-tank underbody leak
Fuel drips or leaks from the tank, typically after contact with road debris or without visible impact damage. Owners report steady dripping that creates strong gasoline odor and poses fire risk.
When: Early in ownership; complaint #1 at ~2 months / new vehicle
Symptoms owners cite: Strong gasoline smell outside vehicle; Gasoline dripping from underneath vehicle; Odor intensifies during/after road trips
Repairs/costs cited: Dealership blamed owner impact; insurance adjuster noted missing protective skid plate (listed as optional by Ford). Repairs covered by owner's insurance, not warranty.
Recalls/TSBs owners mention: Dealership denied warranty coverage, claiming owner-caused damage. Ford stated skid plates optional except on 4WD models.
EVAP canister / fuel-system vent failure
Fuel tank cannot vent properly during refueling. Pressure builds in tank, causing fuel pump to shut off prematurely and fuel to back up out of the filler neck onto the driver and ground. TSB 07-25-3 and DTC P0451 documented by multiple owners. Owners note bubbling sounds in fuel lines and extended fill times (15-45+ minutes for full tank).
When: Typically 48,000–90,000 miles; recurring after repair
Symptoms owners cite: Fuel pump shuts off every 1/2 to 3 gallons; Gasoline sprays or spills back out of filler neck; Bubbling sounds in fuel line; Extremely slow refueling (10–45 minutes for full tank); Check Engine Light with DTC P0451
Codes mentioned: P0451
Repairs/costs cited: TSB 07-25-3 replacement of EVAP canister and vapor hose. Dealer part cost cited as $400+; owners reported sourcing used parts cheaper. Failure recurred in multiple cases within months or years of repair.
Recalls/TSBs owners mention: TSB 07-25-3 issued; Ford acknowledged issue affects explorers built before 11/27/07. No recall issued despite safety complaints. Manufacturer denied liability in at least one case (complaint #5). Dealer service department acknowledged issue happens 'all the time.'
Fuel-sending unit / fuel-fill valve malfunction
Fuel sending unit, sensors, tubes, or associated fill-valve components fail, preventing normal fuel entry or causing overflow during refueling. Pump shuts off at short intervals (10-cent increments) as if tank is full when it is not, or canister becomes 'dirty' and restricts flow.
When: 70,000+ miles; also reported early in ownership at ~48,000–90,000 miles
Symptoms owners cite: Fuel pump shuts off at brief intervals while tank is not full; Gasoline overflows during refueling; Difficulty adding fuel in timely manner; Recurrence after repair
Repairs/costs cited: Dealer replacement of fuel sending unit, sensors, and tubes. Multiple dealer visits required in at least one case; problem recurred. Canister replacement after heavy snow blamed on 'dirty emissions canister,' but owner questioned design adequacy for snow regions.
Fuel-rail leak
Fuel leaks from fuel rail onto engine, creating gasoline smell inside and outside vehicle.
Symptoms owners cite: Gasoline smell inside and outside vehicle; Fuel visible on engine
Repairs/costs cited: Dealer identified fuel-rail leak; specific repair details not provided in narrative.
Engine surge and stalling (unconfirmed fuel-system link)
Vehicle experiences unexpected engine surges, difficulty accelerating, and stalling at intersections. Owner researched and found similar complaints but could not definitively connect to fuel system. Wrench light appears during event. Possible connection to fuel-system pressure or sensor malfunction but not confirmed in narrative.
When: Unspecified mileage
Symptoms owners cite: Unexpected engine acceleration without driver input; Vehicle maintains speed like cruise control is on; Engine does not respond to throttle input; Popping sound from engine; Engine stalls at intersections; Wrench / Check Engine light
Repairs/costs cited: No repair attempted at time of complaint; owner unable to afford diagnosis due to financial constraints.

At what mileage does the fuel system typically fail?
Across the 14 complaints that reported odometer mileage, most fuel system failures cluster between 48,000 and 88,000 miles, with the median around 60,460. A quarter of owners report trouble before 48,000; a quarter make it past 88,000. 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.
