Acura Fuel Pump Recall: What Every Owner Needs to Know in 2026

If you own a 2017-2020 Acura model, your vehicle may be part of a massive fuel pump recall affecting approximately 2.6 million vehicles in the United States. American Honda has announced a voluntary recall to replace defective fuel pumps free of charge, as the fuel pump impeller was improperly molded and can deform over time, potentially causing the engine to stall while driving. This recall covers popular Acura models including the ILX, MDX, MDX Sport Hybrid, NSX, RDX, RLX, and TLX from model years 2017 through 2020. Even if you haven't received a notification yet, you should check your vehicle's eligibility immediately using the VIN lookup tools provided by Honda and Acura.

1. Why Is There an Acura Fuel Pump Recall?

The root cause of this recall is a manufacturing defect in the fuel pump impeller. According to American Honda's official statement, "The fuel pump impeller was improperly molded, resulting in low density impellers". Over time, these low-density impellers can absorb fuel and swell, eventually deforming and interfering with the fuel pump body. This interference can render the fuel pump inoperative, meaning your engine may not start or could stall suddenly while you're driving.

The safety risk is real: A stalled engine while driving, especially at highway speeds, significantly increases the risk of a crash. However, Honda has stated that "no reports of crash or injury related to this issue" have been received as of the recall announcement.

2. Which Acura Models Are Affected?

The recall covers a wide range of Acura models. Here is the complete list based on Honda's official release:

Acura Models Recalled:

  • 2018-2020 Acura ILX
  • 2018-2020 Acura MDX
  • 2018-2020 Acura MDX Sport Hybrid
  • 2017-2020 Acura NSX
  • 2018-2020 Acura RDX
  • 2018-2020 Acura RLX
  • 2018-2020 Acura TLX

Note: This recall also includes many Honda models, such as the 2018-2020 Accord, 2017-2020 Accord Hybrid, 2018-2020 Civic, Civic Type R, 2018-2020 CR-V, 2018-2019 Fit, 2018-2020 HR-V, 2019-2020 Insight, 2018-2020 Odyssey, 2019-2020 Passport, 2017-2020 Pilot, and 2018-2020 Ridgeline.

It is important to understand that not every vehicle within these model years is affected. You must check your specific Vehicle Identification Number (VIN) to confirm whether your car is included in the recall.

3. How to Check If Your Acura Is Affected

Honda has made it easy for owners to check their vehicle's recall status. You can use any of the following methods:

  • Online VIN Lookup: Visit www.recalls.acura.com or www.recalls.honda.com and enter your VIN.
  • Phone Support: Call Honda customer service at 1-888-234-2138 to speak with a representative.
  • NHTSA Database: You can also check the National Highway Traffic Safety Administration (NHTSA) website at www.safercar.gov and enter your VIN for recall information.

Pro tip: Your VIN is located on the driver's side dashboard near the windshield, on the driver's side door jamb, or on your vehicle registration and insurance documents.

4. What Will the Recall Repair Include?

If your vehicle is part of the recall, here is what you can expect:

The repair is completely free of charge. Honda will replace the entire fuel pump module in your vehicle. This includes the fuel pump assembly, not just the impeller. The replacement parts are redesigned to prevent the density issue from recurring.

Timing of the repair: As of the December 2023 announcement, Honda stated that "countermeasure replacement parts are not available in sufficient quantities for all recalled vehicles". Initial mailed notifications to owners began in early February 2024, with subsequent mailings as parts become available. If you haven't received a notification yet, you can still contact your local Acura dealer to schedule the repair once parts are in stock.

5. Symptoms of a Failing Fuel Pump

If your Acura has a defective fuel pump, you may notice these warning signs before the pump completely fails:

  • Hard starting: The engine may crank longer than usual before starting, or may not start at all.
  • Engine stalling: The engine may suddenly stop while driving, especially at low fuel levels or in hot weather.
  • Loss of power: You may experience hesitation or lack of acceleration when pressing the gas pedal.
  • Whining noise: A loud whining or humming sound coming from the fuel tank area, particularly when the engine is running.
  • Check engine light: The check engine light may illuminate on your dashboard.

Safety warning: If you experience any of these symptoms, especially stalling while driving, you should have your vehicle inspected immediately. Driving with a failing fuel pump is dangerous and can leave you stranded.

6. What If You Already Paid for a Fuel Pump Replacement?

If you previously paid out of pocket for a fuel pump replacement on your Acura due to this defect, you may be eligible for reimbursement. Honda has a process for owners who have already incurred expenses related to this recall. Contact Honda customer service at 1-888-234-2138 and provide documentation of the repair to inquire about reimbursement options.

Additionally, note that this recall is an expansion of previous fuel pump recalls. The NHTSA campaign numbers include 23V858000, which expands on earlier recalls 21V-215 and 20V-314. This means that if your vehicle was already repaired under a previous recall, it should still be covered.

7. How Long Does the Repair Take?

The fuel pump replacement typically takes 2 to 4 hours if there is an access panel in the vehicle, and 4 to 6 hours if the fuel tank needs to be dropped. Your Acura dealer can provide a more accurate estimate after inspecting your vehicle. It is recommended to bring your vehicle with a low fuel level to speed up the repair process.

9. Additional Tips for Acura Owners

Check for multiple recalls: Your Acura may have other open recalls besides the fuel pump issue. The NHTSA database shows that Acura has had recalls for driveshaft failures, software updates, and other components. Always check your VIN for all open recalls.

Keep your fuel tank above a quarter full: Running your tank low frequently causes the fuel pump to work harder and run hotter, which can shorten its lifespan. Maintaining at least a quarter tank of fuel helps cool and lubricate the pump.

Use quality fuel: Contaminated or low-quality fuel can damage the fuel pump and clog the fuel filter. Stick with reputable gas stations to protect your fuel system.

Replace the fuel filter: When replacing the fuel pump, it is a good practice to also replace the fuel filter and strainer. This prevents debris from damaging the new pump and ensures optimal fuel flow.
