What stands out
Owners have filed 74 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.
Fuel system accounts for 27% of all owner complaints filed against this vehicle, across 10 categories tracked.
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
The 2007 GMC Envoy suffers from a defective fuel gauge system centered on the fuel sending unit in the tank. Owners describe a consistent failure pattern: the gauge reads inaccurately, jumps erratically between empty and full, or gets stuck on empty regardless of actual fuel level. The low-fuel warning light and check engine light often illuminate in tandem with the gauge fluctuations. This problem typically surfaces between 29,000 and 75,000 miles, often shortly after warranty expiration.
The real danger is unexpected stalling. Owners report running out of gas on interstates and city streets without warning because the gauge showed fuel remaining. One owner lost power steering during a turn at an intersection when the car stalled. Others were stranded roadside, some in high-crime areas. The workaround—refueling every 250 miles or tracking mileage obsessively—isn't a solution.
GM issued Special Coverage Adjustment Notice #10054E acknowledging fuel level sensor contact wear and offering to cover 50% of the repair cost. However, owners report inconsistent application and denied reimbursement requests. Full repair costs range $250 to $871 depending on labor rates; the fuel tank must be dropped to replace the sending unit. Dealers confirm this is a known, common failure across Envoy, Trailblazer, and Rainier models, yet no full recall covers the 2007 Envoy.

Failure modes owners describe
Fuel gauge inaccuracy and erratic behavior
Fuel gauge displays incorrect fuel level, fluctuates wildly between empty and full, or becomes stuck on empty regardless of actual fuel level in tank. Low fuel warning light and check engine light illuminate intermittently or continuously. Occurs both at rest and while driving.
When: Typically 29,000 to 75,000 miles; some owners report onset within 3 years of purchase or shortly after warranty expiration
Symptoms owners cite: Gauge reads empty when tank is full; Gauge jumps between empty and full unpredictably; Gauge stuck on empty; Low fuel warning light comes on with full tank; Check engine light illuminates when gauge fluctuates; Gauge may work correctly for a period then fail again
Codes mentioned: P0460 - Fuel level sensor circuit malfunction
Repairs/costs cited: Fuel sending unit replacement required; involves dropping fuel tank. Repair costs cited range from $250 to $871 for parts and labor; parts alone estimated $500-$600; labor $91/hour or higher at dealership
Recalls/TSBs owners mention: GM Special Coverage Adjustment Notice #10054E covers fuel level sensor contact wear; GM offered 50% cost sharing on some repairs; some owners received reimbursement requests but did not receive refunds; manufacturer claimed 'no awareness' of problem in some dealer interactions despite widespread internet reports
Unexpected engine stalling due to fuel system malfunction
Engine stalls or hesitates when vehicle slows down, exits highway, comes to stop, or when fuel tank level drops to 1/4 or below. No warning codes appear on dashboard in some cases. Vehicle may rev and catch or simply quit quietly.
When: Typically triggered when fuel tank level approaches 1/4 full or lower
Symptoms owners cite: Engine stalls at low speed or when coming to a stop; Engine stalls when exiting highway; Engine hesitates or drags when accelerating; No dashboard warning lights or codes present; Miles remaining counter shows lower mileage after stall event; Vehicle runs normally at higher speeds
Repairs/costs cited: Dealer initially misdiagnosed as throttle mechanism cleaning; no permanent resolution achieved through standard troubleshooting
Recalls/TSBs owners mention: Dealer kept vehicle 3 days, found no codes, declined further investigation citing cost; GM customer service dismissed owner complaint
Fuel level sensor circuit and sending unit failure
Fuel sending unit (located in fuel tank) fails internally, causing fuel gauge to provide inaccurate or no readings. Some narratives suggest fuel line clogging may also contribute, though primary cause cited is sensor contact wear.
When: Occurs across wide mileage range, commonly reported at 29,000 to 75,000 miles
Symptoms owners cite: Fuel gauge fails to display accurate reading; Fuel gauge becomes completely non-functional; Gauge readings do not correlate to actual fuel in tank; Problem worsens over time from intermittent to complete failure
Codes mentioned: P0460 - Fuel level sensor circuit malfunction
Repairs/costs cited: Fuel sending unit replacement; requires fuel tank drop and sensor replacement; costs $250-$871 depending on labor rates and dealer; some owners cite clogged fuel line diagnosis at $600-$800
Recalls/TSBs owners mention: GM Special Coverage Adjustment Notice #10054E; partial reimbursement program offered but inconsistently applied; some reimbursement requests reportedly never processed; dealer stated this is a known, common failure
Fuel system safety hazard - unplanned fuel depletion and stranding
Inaccurate fuel gauge causes owners to unexpectedly run out of gas while driving, creating hazardous situations including highway stalls, loss of power steering, traffic backup, and emergency stops in unsafe locations. Owners unable to determine true fuel level must refuel every 250 miles or use trip odometer to estimate remaining fuel.
When: Occurs whenever gauge malfunction prevents accurate fuel level awareness
Symptoms owners cite: Vehicle runs out of fuel without warning; Stranding on highway or interstate; Loss of power steering during stall; Emergency stop or towing required; Owner forced to refuel every 250 miles as workaround; Owner must rely on trip odometer to estimate fuel remaining
Repairs/costs cited: Workaround: owners keep tank above 1/4 or refill every 250 miles; proper repair requires fuel sending unit replacement
Recalls/TSBs owners mention: No recall issued despite safety concerns raised in multiple complaints; NHTSA investigation mentioned but recall campaign #14V223000 applied only to certain vehicles; GM has not expanded recall to cover 2007 Envoy

What owners are reporting 1 most recent
Fuel sending unit is defective after 40,000 miles. Tank readings inaccurate. I live in an urban area where it is not safe to be out of fuel and broken down on side of road. Dealer admits this problem is common for gm envoy/rainer/trailblazer - numerous online forums list this as a defect - yet gm does nothing to rectify the problem. Item is out of warranty and gm won't cover it. *tr

Common questions
How serious is the fuel system problem on the 2007 GMC Envoy?
It's a documented issue but not catastrophic. 74 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 63 complaints that reported odometer mileage, most fuel system failures cluster between 41,000 and 61,300 miles, with the median around 50,000. A quarter of owners report trouble before 41,000; a quarter make it past 61,300. 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.
