What stands out
Owners have filed 125 fuel system complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA fuel system complaint has been filed on this vehicle in over 9 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 Preliminary Information communicates to the dealer the process for downloading or updating operating software for the Tire Pressure Monitor, Active Fuel Injector tester, multi media tester, PICO Scope, GR8 starting/charging tester and Vehicle Data Recorder tools, giving website address and step by step instructions to complete the update.

The failure pattern owners describe
Owners consistently describe a strong gasoline odor inside and around the cabin, often developing gradually over weeks or months. The source is the plastic fuel pump module reservoir mounted on top of the fuel tank—its supply and return ports crack under heat and road vibration, spraying or pooling fuel underneath the vehicle. The plastic hose connections press-fitted to the pump fail similarly. One owner found a softball-sized fuel puddle after returning home. Another discovered fuel run marks cascading down the tank during a routine inspection.
The problem emerges across the mileage spectrum: some owners reported it as early as 36,000 miles, others at over 120,000 miles. Hot climates and prolonged high temperatures accelerate failure. One owner in East Texas experienced the leak only after 200+ days above 90 degrees; another in Maryland flagged abnormally hot conditions as the trigger.
Diagnosis requires tank removal and EVAP testing to confirm the leak origin—visible inspection alone often misses it. Repair means replacing the entire fuel pump module assembly; the hoses cannot be isolated and fixed. Owners cite repair costs of $400 to $1,000 depending on parts and labor.
GM's response has been narrowly scoped. The October 2009 recall (Campaign 09V419000) covered only Arizona and Nevada for 2006 models. A broader "special coverage" warranty extended to warm-weather states but capped coverage at 10 years or 120,000 miles. Many owners outside these boundaries or exceeding mileage limits were denied coverage, even when their VIN matched the affected population. Some were told to pay diagnostic fees to a dealer that would then refuse the repair as out of recall scope.

Failure modes owners describe
Cracked fuel pump module reservoir ports/hoses
The plastic supply or return ports on the modular fuel pump reservoir assembly crack, typically at hose connection points. Fuel leaks from the cracked area. In severe cases, fuel drips onto the ground and pooling occurs underneath the vehicle. The cracks develop due to heat and road vibration.
When: 3.5 to 5+ years of ownership; typically 36,000–128,000 miles; failure more evident in hot climates and after prolonged high-temperature exposure
Symptoms owners cite: Strong gasoline odor inside and outside the cabin (most common symptom); Gasoline pooling under the vehicle; Run marks and wet stains on fuel tank from leaking fuel; Gasoline fumes entering the passenger compartment and trunk; Longer crank times or harder starting; Check Engine Light and Check Gas Cap Light illumination; Loss of power or stalling (in isolated cases linked to fuel starvation)
Codes mentioned: NHTSA Campaign 09V419000, GM Recall No. 090226, Special Coverage Bulletin #09275/09275A, EVAP test revealing smoke from tank area
Repairs/costs cited: Entire fuel pump module assembly must be replaced; hoses cannot be repaired individually. Repair costs cited range from $400–$1000+ including parts and labor. OEM fuel pump module parts purchased at dealer or aftermarket replacement. In some cases owners reported parts arriving damaged on first shipment.
Recalls/TSBs owners mention: GM issued NHTSA Campaign 09V419000 recall (published Oct 29, 2009) for 2006 Chevrolet Cobalt and Saturn Ion vehicles originally sold or registered in Arizona and Nevada, and 2007 models in Arizona, California, Florida, Nevada, and Texas. A broader Special Coverage (10 year/120,000 mile warranty) was extended to 2006 and 2007 models registered in additional warm-weather states (Alabama, Arkansas, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, North Carolina, New Mexico, Oklahoma, South Carolina, Tennessee, and Texas). However, vehicles outside the recall and special coverage regions—or exceeding mileage limits—were denied coverage. Multiple owners report GM refused repair even when VIN matched the recall list but the registration state did not qualify.
Fuel line corrosion and cracking
Fuel lines, particularly the plastic connector elbows and hoses press-fitted to the fuel pump sending unit, crack or corrode over time. Corrosion is especially severe just in front of the rear driver-side wheel, where the pipeline has multiple bends and the protective coating fails.
When: 5+ years of ownership; reported at 55,200–84,000 miles
Symptoms owners cite: Strong gasoline odor inside and outside the vehicle; Gasoline pooling under the vehicle, particularly on driver side; Visual inspection shows corroded or cracked fuel lines; Longer crank times when starting
Codes mentioned: EVAP test revealing leaks
Repairs/costs cited: Fuel pump module must be replaced as lines are press-fitted and cannot be repaired separately. One owner reported corrosion so severe it resembled rust, despite vehicle age.
Fuel regulator issues and fuel temperature regulation failure
One owner reported fuel regulator failure causing intermittent power loss and difficulty starting. Another reported fuel not heating to proper temperature, causing reduced fuel economy (approximately 30% fewer miles per gallon).
When: Multiple occurrences over vehicle lifetime; one case at approximately 38,200 miles, another at 36,000 miles
Symptoms owners cite: Car suddenly loses power while accelerating (5–8 second loss); Tires spin out and vehicle loses control in wet/icy/slippery conditions; Car spins and loses power when driving uphill; Fuel not heating to proper temperature (separate complaint); Significantly reduced fuel economy
Repairs/costs cited: One case required fuel regulator replacement; dealer kept vehicle for over three weeks. Another case involved replacement of wiring harness due to air conditioning issue. One vehicle required fuel injector replacement and fuel tank replacement.
Recalls/TSBs owners mention: One dealership was unable to duplicate the failure. Another case resulted in an unauthorized dealer driver crashing the vehicle while attempting diagnosis.
Persistent gasoline smell without visible leak
Strong, overwhelming gasoline odor inside and outside the vehicle, sometimes filling the garage. In some cases, no visible leak is immediately apparent—the source is the cracked fuel pump module ports or connections at the top of the tank that are difficult to inspect without tank removal.
When: Reported at 36,000–124,400 miles; symptoms can develop suddenly or gradually worsen over weeks
Symptoms owners cite: Very strong gasoline odor in cabin and around vehicle exterior; Odor fills the garage; Odor strong enough to make occupants ill; No visible fuel stain initially, or stain attributed to prior work
Codes mentioned: Check Engine Light (in some cases), EVAP test with smoke visible from tank area
Repairs/costs cited: Diagnostic often requires tank removal and further EVAP testing to pinpoint the leak at the fuel pump module connections.
