Owners report the 2021 Tahoe's fuel system repeatedly failing without warning. Most common: the fuel pump power control module cuts power mid-drive or prevents the engine from starting. Drivers have stalled at highway speeds, during turns, at red lights, and while idling. Some vehicles fail before 1,000 miles; others at 60,000–111,000 miles.
When the module fails, the engine stalls abruptly. Restart attempts often fail the first time. On some vehicles, the transmission locks in Park and the gear shifter freezes. Owners report pressing OnStar buttons, waiting 40 minutes on roadsides, needing tow trucks to extract vehicles from parking garages. Check engine lights may illuminate, but many stalls occur with no warning whatsoever.
NHTSA recall 21V739000 addresses this, but many owner VINs fall outside the recall. Even those within the recall have reported the failure returning 2+ years after the "fix." Dealers cite the fuel pump control module as the culprit (part #13544060) and confirm it requires replacement. But parts go on back order for weeks or longer, leaving repaired vehicles waiting and unrepairable vehicles grounded.
One separate failure: a high-pressure fuel pump developed a crack and leaked gasoline into the cabin, a hazard with children aboard. Another owner reported water contaminating the fuel tank. A fuel pump drive failure occurred after a separate powertrain recall was completed.
The fuel pump power control module fails, cutting fuel delivery to the engine. This causes the engine to stall without warning during driving or prevent the engine from starting. Some owners report the failure recurring even after dealer replacement under recall 21V739000, suggesting the recall remedy may be incomplete or parts continue to fail.
When: Mileage ranges from 616 miles to 111,000 miles; earliest failures within first year of ownership; some reported as recurring 2+ years after initial recall repair
Symptoms owners cite: Engine stalls without warning while driving at various speeds (20–70 MPH); Vehicle fails to start when parked; Message displayed on instrument panel: 'Restart the vehicle' or 'Conditions not met to restart'; Message displayed: 'Press Start Again'; Engine sputters during restart attempts; Check engine warning light may illuminate (inconsistent); Transmission stuck in Park after stall; gear shifter will not move; No response to accelerator pedal depression; Vehicle may require tow truck to extract from tight spaces (transmission lock)
Codes mentioned: Fuel pump power control module failure diagnosis (multiple narratives cite part #13544060)
Repairs/costs cited: Fuel pump power control module replacement required. Part #13544060 cited. In several complaints, dealer reported parts on back order, delaying repairs. One owner reported the part was replaced in 2022, then failed again by the complaint filing date. Repair costs not specified, but one owner refused repair due to cost.
Recalls/TSBs owners mention: NHTSA Campaign Number 21V739000 (Fuel System, Gasoline). Some owner VINs were included in recall; others were not, despite exhibiting identical failures. Owners reported manufacturer opened cases but provided limited assistance. Some directed to NHTSA Hotline. One manufacturer advised recall remedy no longer covered under recall after ~2 years, but repair covered under warranty; parts on back order prevented completion.
The high-pressure fuel pump develops a crack in its housing, causing gasoline to leak into the cabin. This is a safety and health hazard, particularly with children in the vehicle. Reported in one narrative but distinct from the more common power control module failures.
When: 51,264 miles
Symptoms owners cite: Abnormal gasoline odor inside cabin during cold start; Odor stronger when heater is activated; No warning light illuminated
Codes mentioned: High-pressure fuel pump (HPFP) cracked—leaking gasoline
Repairs/costs cited: High-pressure fuel pump replacement required. Vehicle not repaired as of complaint date.
Recalls/TSBs owners mention: Manufacturer was informed of the failure; no further response documented.
Water leaks into the fuel tank, contaminating the fuel and causing fuel pump failure and engine stall. The vehicle's transmission becomes locked in Park after stalling.
When: 27,000 miles
Symptoms owners cite: Vehicle stalls without warning during driving; Transmission moves into Park independently; Gear shifter will not move after stalling
Codes mentioned: Water leak into fuel tank
Repairs/costs cited: Dealer lacked adequate tool to unlock transmission; tool obtained days later. Vehicle not repaired as of complaint date.
Recalls/TSBs owners mention: Manufacturer notified; advised they would follow up but no callback received at time of complaint.
The intake fuel pump fails, causing loss of motive power. In one narrative, the intake pump was replaced, but the failure recurred five months later and was attributed to the fuel pump power control module on the second diagnosis.
When: 35,000 miles at initial failure; recurred ~5 months later
Symptoms owners cite: Vehicle loses motive power during left turn with foot on accelerator; Vehicle shakes; Engine fails to restart after stall
Codes mentioned: Intake fuel pump failure
Repairs/costs cited: Intake fuel pump replaced at first dealer. Failure recurred; second dealer diagnosed fuel pump power control module failure and replaced it.
Recalls/TSBs owners mention: Manufacturer notified of initial failure.
The fuel pump drive fails, resulting in loss of motive power and unintended transmission shift to neutral. Reported after a separate powertrain recall (24V797000) was completed, suggesting possible interaction with recall work or unrelated underlying defect.
When: ~69,000 miles
Symptoms owners cite: Vehicle displays 'Reduced Power' message; Rear wheels lock up; After recall repair, vehicle unintendedly shifts into neutral at 10 MPH; Message displays: 'Press Start Again'; Failure recurs twice while returning to dealer
Codes mentioned: Fuel pump drive failure
Repairs/costs cited: Vehicle not repaired as of complaint date.
Recalls/TSBs owners mention: Manufacturer confirmed VIN was no longer under recall 24V797000 and opened a case.
