2007 Toyota Tundra fuel system problems
moderate 14 complaints filed with NHTSA · avg repair $1,200 · see fuel system across all vehicles →
Among the 6 model years of Toyota Tundra in our records for fuel system problems, this one ranks #3 by owner-complaint volume.
The failure pattern owners describe
Buyer takeaway: The 2007 Tundra fuel system has multiple documented failure modes—air injection pump corrosion causing power loss, fuel tank strap rust, fuel pump intermittent stalling, and accelerator issues including stuck pedals and post-recall drivability problems. Repair costs for air injection failure alone run $2,100–$2,300, with manufacturer coverage often partial or limited by state.
The 2007 Tundra fuel system failures break into several distinct patterns. Air injection pump corrosion is the most common complaint: pumps and switching valves corrode due to water infiltration, causing sudden power loss and check engine lights between 41,000 and 110,000 miles. Repair runs $2,100–$2,300; Toyota offered partial coverage ($600) in one case. Dealers cite an extended warranty (3–5 years/36,000–70,000 miles), but eligibility varies by state.
Fuel tank mounting straps rust and fail starting around 55,000 miles, allowing the tank to shift or partially detach. One owner heard loud noise and found brackets coming loose; another had a tank bolt fracture. A dealer confirmed this is common for the model year.
Fuel tank O-ring defects cause fuel leaks and strong odor as early as 45,000 miles. One owner also reports intermittent fuel pump failure causing engine stall at highway speed (75 mph) with no warning codes—Toyota advised keeping the tank at least 1/4 full.
Accelerator pedal sticking recurs even after recall repair and shim installation. One owner reports the dealer service manager denied a recall existed despite owner providing Toyota's own recall notice. Two owners describe new drivability problems (stalling, lurching, hesitation) after the accelerator recall repair, suggesting the reprogramming made throttle response overly sensitive.
Failure modes owners describe
Air injection pump and valve corrosion/failure
Air injection pumps and air injection switching valves corrode and fail, causing loss of engine power and illumination of check engine light. Dealers cite water infiltration as root cause. Repair involves replacement of corroded pump assemblies.
When: 41,000 to 110,000 miles
Symptoms owners cite: loss of motive power when accelerating; check engine light illumination; sudden loss of power at highway speed
Codes mentioned: P0410 or similar air injection system codes
Repairs/costs cited: Air injection pump replacement; reported cost $2,100–$2,300. Toyota offered partial coverage ($600) on at least one vehicle.
Recalls/TSBs owners mention: Extended warranty offered in some cases (3 years/36,000 to 5 years/70,000 miles), but coverage limited by state and mileage. Toyota acknowledged defect involving water infiltration in at least one case.
Fuel tank strap corrosion
Fuel tank mounting straps corrode and fail, allowing the fuel tank to move or partially detach. Bolts fracture and detach. Noted as a common failure for this year, make, and model.
When: 55,000 to 130,000 miles
Symptoms owners cite: fuel tank skid guard brackets partially detach; loud noise from under vehicle; fuel tank bolt fracture
Repairs/costs cited: Fuel tank strap replacement required. One owner temporarily secured brackets with rope. No repair costs cited.
Recalls/TSBs owners mention: One owner reported Toyota extended warranty to cover half of repair costs.
Fuel tank O-ring leak
Defective O-ring allows fuel tank to leak. Dealer noted the failure is common for 2007 Tundra model.
When: 45,000 miles
Symptoms owners cite: strong gasoline odor; fuel leaking from vehicle
Repairs/costs cited: O-ring replacement needed. Vehicle not repaired per narrative.
Intermittent fuel pump failure
Fuel pump fails intermittently, causing engine to stall at low and highway speeds without triggering diagnostic codes. Owner reports similar cases documented online with similar Toyota responses.
When: Mileage not specified; owner reports 30-day delay before replacement
Symptoms owners cite: engine stops running randomly; stalling at low speed; stalling at highway speed (75 MPH); no check engine light or error codes
Repairs/costs cited: Fuel pump replaced after 30-day delay. Toyota suggested keeping fuel tank at least 1/4 full as temporary measure.
Accelerator pedal sticking
Gas pedal sticks to the floor, causing sudden unintended acceleration. Related to recalled accelerator issue, but dealer service manager initially denied recall existed even when owner cited recall documentation.
When: 41,000 miles (reported October 2009 recall notice)
Symptoms owners cite: accelerator pedal stuck to floor; unintended acceleration in forward and reverse; loss of power on depression
Repairs/costs cited: Shim installed in February 2010; pedal continued sticking after repair.
Recalls/TSBs owners mention: Toyota recalled 2007 model (January 2010). One owner reported dealer service manager denied recall despite owner providing recall notice from Toyota website.
Post-recall accelerator sensitivity and drivability
After dealer completed accelerator pedal recall repair, vehicle exhibits new drivability problems: stalling on takeoff, lurching on rough road surfaces, hesitation followed by sudden acceleration. Owner reports accelerator became overly sensitive after reprogramming.
When: Post-repair (after accelerator recall completed)
Symptoms owners cite: stalling when taking off; lurching/acceleration at each bump on rough surface; hesitation then sudden lurch ahead; truck operates worse than before repair
Repairs/costs cited: Accelerator reprogramming completed during recall; no further repair noted despite dealer acknowledging problem.

Common questions
How serious is the fuel system problem on the 2007 Toyota Tundra?
It's a documented issue but not catastrophic. 14 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 13 complaints that reported odometer mileage, most fuel system failures cluster between 26,300 and 74,268 miles, with the median around 45,000. A quarter of owners report trouble before 26,300; a quarter make it past 74,268. 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.
