When does it fail?
Of the 22 fuel system complaints filed for the 2007 Pontiac G5, here's the actual mileage breakdown — failures cluster heaviest at 25,000-50,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
No new NHTSA fuel system complaint has been filed on this vehicle in over 12 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering fuel system on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This service bulletin provides the technician with additional information on fuels, fuel additives and fuel management.

The failure pattern owners describe
Strong fuel odor — sometimes noticeable only when parked, eventually detected while driving — is the most common complaint. Owners then discover fuel leaks ranging from slow drips to gallons pouring during refueling. The culprits are a plastic fuel pump module (the part that holds the pump and connects the fuel neck hose to the tank) and the fuel tank itself, both prone to cracking.
The fuel pump module cracks typically at the return port or the connection point where the fuel neck hose attaches. Failures occur as early as 38,000 miles and as late as 151,000 miles. One owner had a replacement pump crack again just five months after a warranty installation. The plastic fuel tank develops separate cracks, often discovered only after the pump is replaced — suggesting dealers don't routinely inspect it during pump work.
One vehicle caught fire at rest, with the fire department pinpointing the fuel pump area as the origin.
GM issued two recall campaigns (09V419000 and 12V459000) but limited them to specific states and VINs. Owners outside those boundaries report being denied coverage despite having identical failures. Dealers often refuse to perform the work if a VIN isn't flagged in the system. Repair costs at dealerships exceed $500 when out of warranty; independent shops also charged for diagnosis and replacement.
Failure modes owners describe
Cracked fuel pump module
Fuel pump module (also called fuel pump assembly) develops cracks, typically at the return port or fuel neck connection point, causing fuel leaks and fumes. Multiple owners report the crack occurs despite the component being plastic and designed to pressurize fuel.
When: 38,420 to 151,000 miles; some failures noted as early as routine maintenance visits
Symptoms owners cite: Strong fuel odor inside and around vehicle; Visible fuel leak from under vehicle or near driver's side door; Fuel fumes emitted into cabin; Hard cold start after sitting a few hours; Check engine warning light illuminated; Loss of motive power while driving (one report)
Codes mentioned: NHTSA Campaign 09V419000 (Fuel System, Gasoline: Delivery: Fuel Pump), NHTSA Campaign 12V459000 (Fuel System, Gasoline: Delivery: Fuel Pump)
Repairs/costs cited: Fuel pump module replacement; some dealers charged $500+ when outside recall scope. One owner reported replacement pump cracked again 5 months after warranty installation.
Recalls/TSBs owners mention: Recall campaigns 09V419000 and 12V459000 issued but limited to specific states and VINs; manufacturer refused coverage for vehicles outside designated geographic areas despite identical failures.
Cracked fuel tank
Plastic fuel tank develops cracks, typically near the fill area or neck hose connection. Appears to be separate issue from recalled fuel pump module; owner research and dealership technician observations suggest tanks should have been included in recall scope but were not.
When: 38,420 to 103,000 miles; some discovered during pump replacement or routine service
Symptoms owners cite: Strong fuel odor in and around vehicle; Visible fuel leak (one report: gallons pouring down driveway after fueling); Fuel fumes inside cabin; Leak only when vehicle is being refueled or after fueling
Codes mentioned: NHTSA Campaign 12V459000 (Fuel System, Gasoline), NHTSA Campaign 09V419000 (Fuel System, Gasoline)
Repairs/costs cited: Fuel tank replacement; at least one owner reported the tank crack was discovered after fuel pump recall repair was completed, suggesting technicians may not inspect tank during pump service.
Recalls/TSBs owners mention: No recall issued for fuel tanks despite prior recall for fuel system parts that crack and leak. Manufacturer offers no assistance for tank cracks; owners must pay out of pocket.
Rusted fuel line
Fuel delivery line corrodes or rusts through, causing leak. At least one owner documented this failure; GM performed diagnostic but refused recall coverage despite finding a defect.
When: Unknown mileage; one report at 72,000 miles
Symptoms owners cite: Fuel odor when starting engine; Visible fuel leak under vehicle near driver's side door
Repairs/costs cited: Entire fuel line system replaced at dealer. Owner paid for repair after GM diagnostic confirmed the defect.
Recalls/TSBs owners mention: GM paid for diagnostic but offered no recall assistance or repair coverage.
Vehicle fire initiated from fuel pump area
One vehicle caught fire while parked and unoccupied at owner's residence. Fire department determined fire originated from fuel pump area.
When: 102,000 miles
Symptoms owners cite: Vehicle fire while parked (no driver present)
Repairs/costs cited: Vehicle total loss; fire department extinguished.
Recalls/TSBs owners mention: Manufacturer was notified but no details on response provided.

I took my car to the dealer for fuel leaks and they replaced the recall items( fuel pump) on the fuel system. I drove home and filled it up to find gallons of gasoline pouring down my driveway. Dropped it off at the dealer after hours so the could enjoy the gas leak. Called them to learn that the tank is also cracked near the fill area. They didn't find this during the original fix? Very luck not…

My car gradually began smelling like gasoline at the beginning of november. I thought it was the gas cap, replaced it, and it has not gone away and only become stronger smelling whether the car is in park or driving on the road. It also is hard to start after sitting for a few hours, it will not crank over on the 1st attempt anymore. I have researched on here, and found there was a recall and…

How serious is the fuel system problem on the 2007 Pontiac G5?
It's a documented issue but not catastrophic. 22 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 21 complaints that reported odometer mileage, most fuel system failures cluster between 68,000 and 103,000 miles, with the median around 80,000. A quarter of owners report trouble before 68,000; a quarter make it past 103,000. 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.
