What stands out
No new NHTSA fuel system complaint has been filed on this vehicle in over 6 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 information on the cold start control system in DI engines to reduce cold start emissions and improve fuel economy.
full bulletin at NHTSA ↗This Preliminary Information communication provides information to the technician about vehicles that have a Service Engine Soon Malfunction Indicator Lamp on. Technician will find Diagnostic Trouble Code P2097 or P2099. Technician will need to perform an injector balance or Active Fuel Injector Tester prior to going further. Technician will also need to check for a small leak in the exhaust if published Service Information diagnostics does not lead to a resolution.

The failure pattern owners describe
The 2011 Equinox fuel system exhibits multiple failure patterns. The high-pressure fuel pump is the most consistent complaint: the plunger shaft seal wears and leaks gasoline directly into the crankcase, contaminating engine oil. This happens as early as 11,000 miles and triggers a check engine light, rough running, and hesitation. Owners report stalling on the highway and complete loss of power; one owner limped along at 40 mph after a fuel pump replacement only to have the engine stall again immediately.
Fuel economy is another widespread issue. The 4-cylinder Equinox is rated 32 highway/23 city, but owners consistently report 19–23 mpg regardless of driving conditions or mode. This falls 8–13 mpg short of EPA highway estimates and persists beyond 5,500 miles despite dealer claims of a "break-in period." Chevy blamed seasonal fuel blend changes and declined to fix it.
At higher mileage (90,000–100,000 miles), pistons fail and engines consume excessive oil, causing jerking, abnormal noise, and total loss of acceleration. The timing/balance chain also fails prematurely; one owner replaced it twice before the extended warranty kicked in.
Chevrolet issued a July 2013 letter extending warranty to 10 years/120,000 miles for pump and chain issues, but recall 11195A didn't cover all VINs, and service bulletins were withdrawn from coverage, leaving owners with warranty disputes and repair bills.

Failure modes owners describe
High-Pressure Fuel Pump Leaking into Crankcase
Fuel pump plunger shaft seal wears and allows fuel to leak into the crankcase and engine oil, contaminating it.
When: 11,000 miles reported in one case; affects vehicles across mileage range
Symptoms owners cite: Vehicle stalls and hesitates to accelerate; Check engine warning light illuminated; Engine running rough; Jerking during acceleration; Abnormal engine sounds; Engine consuming excessive oil
Codes mentioned: P0011
Repairs/costs cited: Fuel pump replacement reported; one owner replaced fuel pump and timing chain; repair cost unknown for most cases
Recalls/TSBs owners mention: Chevrolet issued July 2013 letter extending powertrain warranty to 10 years or 120,000 miles for fuel pump and balance chain issues; recall 11195A issued but did not cover all VINs; some TSBs reportedly issued then pulled from warranty coverage
Poor Fuel Economy (Below Rated MPG)
Owners report consistently achieving 19-23 MPG despite EPA ratings of 32/23, with no improvement after 5,000+ mile break-in period.
When: Present from new vehicle; observed through 5,500 miles and beyond
Symptoms owners cite: Fuel economy 8-13 MPG below EPA highway estimate; Fuel economy 8-11 MPG below EPA city estimate; Poor economy on highway with cruise control; Poor economy in ECO mode
Repairs/costs cited: Dealer attributed to seasonal fuel blend changes and break-in period; no repair performed
Recalls/TSBs owners mention: Dealer stated MPG figures are under best driving conditions and declined to fix; manufacturer advised no warranty remedy available
Engine Stalling and Loss of Power
Engine suddenly stalls during highway driving or at low speeds; vehicle becomes difficult to drive and may lose all engine function.
When: Reported at various mileages; one case at 80,000 miles
Symptoms owners cite: Engine stalls without warning on highway; Engine stalls when brake pedal applied at low speed; Complete loss of engine function; Vehicle limited to 40 MPH before stalling completely; Check engine warning light illuminated
Repairs/costs cited: Fuel throttle body suspected by owner; independent mechanic diagnosed fuel pump and camshaft issues requiring replacement; warranty coverage disputed
Recalls/TSBs owners mention: GM issued technical bulletins on throttle body issue but reportedly withdrew warranty coverage; owner stated GM pulled bulletin from powertrain warranty
Balance Chain Failure
Timing/balance chain wears or fails, potentially leading to engine damage or failure under load.
When: Early in vehicle life; one owner replaced twice before 120,000 mile warranty extension
Symptoms owners cite: Check engine warning light illuminated; Engine failure or inoperability under driving conditions; Potential for accident due to sudden loss of power
Repairs/costs cited: Balance chain replaced twice in one vehicle; timing chain replaced in another after stalling incidents
Recalls/TSBs owners mention: Included in July 2013 Chevrolet letter extending powertrain warranty to 10 years or 120,000 miles; subject to recall 11195A
Piston Failure with Excessive Oil Consumption
Pistons fail at high mileage, causing the engine to consume excessive amounts of oil and lose power.
When: Around 90,000–100,000 miles
Symptoms owners cite: Loss of acceleration when depressing accelerator pedal; Vehicle jerking; Abnormal engine sounds; Check engine warning light illuminated; Excessive engine oil consumption
Repairs/costs cited: Independent mechanics diagnosed piston failure; no repairs completed; owners advised to file NHTSA complaint
Recalls/TSBs owners mention: Manufacturer advised owners to file NHTSA complaint; no warranty coverage or recall identified
