The failure pattern owners describe
Owners of 2007 Chevrolet Equinox fuel systems describe persistent gasoline odors that worsen after driving, often concentrated at the rear passenger side where the fuel tank sits. The majority pinpoint a cracked fuel pump module—the component housing the fuel pump on top of the fuel tank—as the culprit. Fuel pools on top of the tank and runs down the sides, sometimes pooling dangerously close to the exhaust system. Some owners report cracks in the fuel pressure lines connecting to the pump, while others cite fuel tank seams separating or the fuel fill neck leaking.
Failures occur across the vehicle's lifetime, from 1,500 miles to 120,000+. Repair costs run $545 to $1,700 in parts and labor, usually requiring complete fuel pump assembly replacement. General Motors issued NHTSA Campaign 12V459000 in September 2012 for this specific issue, but limited it to Arizona, California, Nevada, and Texas. Owners outside those states were repeatedly denied coverage despite identical symptoms; some fought back and secured warranty repairs after reinspection or goodwill gestures. Dealerships initially unfamiliar with the defect, and many owners endured long waits for diagnosis while dealers refused to condemn the part without dropping the tank. Multiple owners report being sickened by fume exposure—headaches, nausea, dizziness—raising concerns about health risks and fire hazard.

Failure modes owners describe
Fuel pump module cracking and leaking
The fuel pump module housing cracks, causing gasoline to leak from the top of the fuel tank. This is the most frequently cited failure across narratives, with owners reporting visible fuel pooling on top of the tank and running down the sides near the fuel fill neck and exhaust system.
When: Failures reported from ~1,500 miles to 112,000+ miles; most commonly between 40,000–80,000 miles on vehicles 3–7+ years old
Symptoms owners cite: Strong gasoline odor inside and around vehicle; Visible fuel leaking from top of fuel tank or running down tank sides; Fuel pooling in depressed area on top of fuel tank; Smell worse after driving; lingering for hours after parking; Gasoline fumes concentrated in garage overnight
Codes mentioned: NHTSA Campaign ID 12V459000 (Fuel System, Gasoline; Delivery; Fuel Pump)
Repairs/costs cited: Fuel pump module or complete fuel pump assembly replacement required; costs cited range $545–$1,700 in labor and parts; some owners report GM covered under warranty if VIN included in recall; most paid out-of-pocket
Recalls/TSBs owners mention: NHTSA Campaign 12V459000 issued September 2012, but limited to Arizona, California, Nevada, and Texas (warm-weather states); many owners outside these states were denied coverage; GM later expanded coverage in some cases after appeal; some dealers applied goodwill 50% discounts
Fuel pump connecting ring separation
The seal or connection ring at the top of the fuel tank where the fuel pump sits separates or fails, allowing fuel to escape. Owners describe the seam near the pump/sending unit assembly opening and leaking.
When: Reported at mileages from ~74,000 miles onward
Symptoms owners cite: Strong gasoline odor from right rear of vehicle (fuel tank location); Visible fuel leaking from tank seam near pump/sending unit; Gas tank seam separation visible on inspection
Repairs/costs cited: Gas tank replacement (often quoted $674–$1,000+ parts and labor) or fuel pump assembly replacement; some owners reported tank cost covered by GM as goodwill but labor deferred
Recalls/TSBs owners mention: Initial refusals; some dealerships later covered full repair under warranty upon reinspection; goodwill gestures noted in a few cases
Cracked fuel pump pipe/pressure line at pump connection
The fuel pressure line or pipe connecting to the fuel pump assembly cracks, often at plastic-to-plastic compression fittings with no clamps. Fuel leaks at this junction and pools on top of the tank near the exhaust system, creating a fire hazard.
When: Reported at mileages from ~1,500 to 100,000+ miles
Symptoms owners cite: Strong gasoline odor from rear of vehicle, especially passenger side; Visible fuel leaking where fuel pressure line connects to pump; Fuel pooling on top of fuel tank in heat-shrinked wrapped connection area; Headaches and nausea reported during extended driving due to fume exposure
Repairs/costs cited: Fuel pump/fuel module/fuel line assembly replacement; cost approximately $1,000–$1,200 parts and labor; often must be replaced as one complete unit
Recalls/TSBs owners mention: No recalls or coverage noted for this specific connection failure; owners paid full out-of-pocket or sought reimbursement without success
Vapor canister failure or pressure relief hose leak
The vapor canister or pressure relief hose fails, allowing pressurized gas vapors to escape. One owner reported strong gas fumes from the pressure relief hose behind the rear tire wall despite no visible fuel leak.
When: Reported after 1+ month of smell buildup
Symptoms owners cite: Strong gasoline odor with no visible fuel leak; Fumes on passenger side near gas cap area; Smell present when stationary and worse after driving
Repairs/costs cited: Vapor canister replacement approximately $98.59 + labor; one owner reported smell persisted after replacement, suggesting incomplete diagnosis
Fuel tank seam or weld failure
The fuel tank itself develops cracks or seams fail at stress points, independent of the pump assembly. Some cases attributed to poor manufacturing with no external damage or wear evident.
When: Reported at ~72,000–84,000 miles and beyond
Symptoms owners cite: Strong gasoline odor, especially from rear passenger side; Visible fuel leaking from tank without external damage or collision history; Fuel smell both inside cabin and outside vehicle
Repairs/costs cited: Fuel tank replacement quoted $600–$674+ labor; one owner replaced tank at own cost; full repair costs $800–$1,500+
Recalls/TSBs owners mention: Most denied warranty or coverage; dealership attributed to normal manufacturing without evidence of damage
Fuel pump corrosion
Fuel pump and associated hoses corrode, leading to fuel leaks and strong odors. One owner discovered corrosion on the fuel pump upon inspection.
When: Mileage not consistently reported; one case at 27,667 miles
Symptoms owners cite: Strong gasoline odor from rear of vehicle; Visible corrosion on fuel pump upon inspection; Potential fuel leak
Repairs/costs cited: Fuel pump and hoses replacement required; cost not fully detailed in narrative
Recalls/TSBs owners mention: Manufacturer offered to pay for repair if diagnostic performed at dealership; vehicle not included in recall 12V459000
Fuel fill neck or filler connection leak
The fuel fill neck area or connections near the filler develop leaks, causing fuel to run down the side of the tank or escape near the fuel cap area.
When: Reported at various mileages; one case at ~72,295 miles
Symptoms owners cite: Strong gasoline odor from rear passenger side; Fuel leaking from top/side of fuel tank near fill neck; Fuel running down tank side adjacent to exhaust system
Repairs/costs cited: Fuel tank replacement or fuel pump line assembly replacement; costs overlap with other repairs ($600–$1,500+)
Recalls/TSBs owners mention: Diagnostics inconclusive; one dealer initially misdiagnosed as fuel pump issue (estimated $1,000) but later found pressure line cracked upon reinspection and covered under warranty
