GMC Gasoline Fuel System Recalls Involve Leaks and Engine Stalls
Fuel leaks and interrupted fuel delivery are the recurring GMC problems in these notices. Acadia appears repeatedly: the 2018 pump-detachment notice covers 2017–2018 vehicles, while separate notices address 2020 pump blockage, 2021 fuel-line attachment, and 2022 AWD rollover-valve sealing. Canyon appears in the pump-detachment notice for 2015–2018 vehicles and the fuel-tank lock-ring notice for 2024 vehicles. Yukon concerns include 2020 fuel-system over-pressurization, a 2021 tank-shell adhesive problem, and a separate 2021 pump-control-module defect affecting Yukon and Yukon XL. Sierra 3500 notices address dual-tank overfilling on 2016–2018 gasoline trucks and inadequate rear-to-front fuel transfer on certain 2025–2026 gasoline trucks.
Warning signs to watch for
- October 15, 2020, Acadia fuel-pump blockage recall: the engine may stall without warning.
- September 23, 2021, Yukon and Yukon XL fuel-pump control-module recall: interrupted fuel flow may cause an unexpected engine stall.
- March 5, 2026, Sierra 3500 dual-tank recall: inadequate fuel transfer may cause an engine stall.
Can you keep driving? What the notices say
The supplied fuel-system notices contain zero stop-driving instructions and zero park-outside instructions. The dual-tank overfill, rollover-valve, fuel-tank lock-ring, pump-detachment, and pump over-pressurization notices do not tell owners to stop driving. The Acadia pump-blockage, Yukon tank-shell adhesive, Acadia fuel-line attachment, and Yukon/Yukon XL pump-control-module notices likewise do not tell owners to stop driving. The March 5, 2026, Sierra 3500 dual-tank fuel-transfer notice also does not tell owners to stop driving. None of these notices supplies a park-outside instruction.
What the free repair involves
Free remedies include pump and pipe replacement for pump detachment, tank replacement for the Yukon adhesive defect, and inspection with fuel-line replacement as necessary for the Acadia attachment defect. The 2026 dual-tank remedy is a free dealer or OTA ECM update. The 2020 Acadia blockage notice specifies pump-module replacement but does not explicitly state that it is free.

Common questions
Which Acadia gasoline fuel-system problems appear in these notices?
The notices identify pump detachment on certain 2017–2018 Acadias, pump-nozzle blockage on certain 2020 vehicles, improperly attached fuel lines on certain 2021 vehicles, and rollover-valve sealing problems on certain 2022 AWD vehicles. Each notice specifies its own remedy.
How do the Sierra 3500 dual-tank recall repairs differ?
For certain 2016–2018 trucks, dealers replace the rear-tank fuel-pump module, inspect the front tank, and replace that tank if necessary. The March 2026 notice for certain 2025–2026 trucks specifies an ECM software update by dealer or OTA. Both remedies are free.
Does the Yukon fuel-tank recall have the same remedy as its pump-control recall?
The February 2021 Yukon notice addresses missing adhesive between tank-shell layers and specifies free fuel-tank replacement. The September 2021 Yukon and Yukon XL notice addresses the fuel pump power control module and specifies free replacement of that module.
