Acura Fuel System Recalls Involving Stalling, Leaks and Gauge Errors
Fuel pump failure and engine stalling recur in the May 2020, March 2021 and December 2023 Acura notices. RDX appears in each of those pump notices, while MDX, ILX and TLX recur in the March 2021 and December 2023 notices. The March 2021 recall specifically covers certain 2019-2020 MDX, MDX Sport Hybrid, RDX and TLX vehicles, plus 2019 ILX vehicles. Other defects require different repairs: the December 2024 notice covers fuel tank weld leaks in 2021-2023 TLX vehicles; the January 2025 notice addresses FI-ECU software in 2022-2025 MDX Type-S and 2021-2025 TLX Type-S vehicles; and the January 2019 notice addresses inaccurate fuel readings in 2014-2019 ILX vehicles.
Warning signs to watch for
- May 28, 2020 fuel pump recall: the engine can stall while driving.
- March 25, 2021 fuel pump recall: fuel pump failure can cause an engine stall while driving.
- December 18, 2023 fuel pump recall: fuel pump failure can cause an engine stall while driving.
- January 23, 2025 FI-ECU recall: the engine may stall or lose power.
- January 24, 2019 ILX recall: the fuel gauge may show more fuel than is actually present, and the vehicle may run out of gas and stall.
Can you keep driving? What the notices say
None of these notices carries a stop-driving or park-outside instruction. The December 2024 TLX fuel tank weld notice does not tell owners to stop driving. Neither do the May 2020, March 2021 or December 2023 fuel pump notices. The January 2025 MDX Type-S and TLX Type-S FI-ECU software notice does not tell owners to stop driving. The January 2019 ILX inaccurate fuel gauge notice also does not tell owners to stop driving. These are the driving instructions described in the supplied notices.
What the free repair involves
Dealers replace the tank assembly for the December 2024 TLX recall; pump assemblies for the May 2020 and March 2021 recalls; and the pump module for December 2023. They reprogram FI-ECU software for January 2025. For January 2019 ILX vehicles, they inspect and, as necessary, replace the tank. Each notice specifies its remedy is free of charge.

Common questions
Which Acura fuel recalls involve software instead of a fuel pump replacement?
The January 2025 notice covers certain 2022-2025 MDX Type-S and 2021-2025 TLX Type-S vehicles. It identifies an FI-ECU software error that may cause stalling or power loss. Dealers reprogram that software free of charge under this recall.
What causes the recalled Acura ILX fuel gauge to read incorrectly?
The January 2019 notice says certain 2014-2019 ILX vehicles may have a deformed fuel tank. This can raise the fuel pump and allow the fuel level float to stick. Dealers inspect and, as necessary, replace the tank free of charge.
What repair does the Acura TLX fuel leak recall require?
The December 2024 notice covers certain 2021-2023 TLX vehicles whose fuel filler neck and fuel tank may have been improperly welded, allowing a leak. Dealers replace the fuel tank assembly free of charge. The notice identifies fire risk near an ignition source.
