Acura Fuel Pump Lawsuit: What Every Owner Needs to Know About Recalls, Settlements, and Your Rights

Here is the bottom line: If you own or lease a 2017–2020 Acura vehicle, you are likely part of an ongoing class action lawsuit regarding defective Denso fuel pumps that can cause sudden stalling, engine failure, and dangerous driving conditions. Honda has recalled over 2.6 million vehicles in the U.S., and a proposed settlement offers extended warranties, free repairs, loaner vehicles, and potential reimbursement for out-of-pocket expenses. However, the settlement is not yet final, and knowing your rights now can save you thousands of dollars and keep you safe on the road.

1. What Is the Acura Fuel Pump Lawsuit About?

The Acura fuel pump lawsuit alleges that Honda Motor Company knowingly sold vehicles equipped with defective fuel pumps manufactured by Denso. The problem centers on the fuel pump impeller—a plastic component that spins to pull fuel from the tank to the engine. According to court documents and NHTSA filings, the impeller was made from a material that absorbs fuel and becomes warped over time . A warped impeller can cause the fuel pump to fail completely, leading to:

  • Engine stalling while driving, especially at highway speeds
  • Difficulty starting the vehicle
  • Complete loss of power to the engine, which also disables power steering and braking assistance
  • Sputtering or hesitation during acceleration

The lawsuit was filed in May 2020 in the U.S. District Court for the Northern District of Alabama, under the case Tucker Oliver v. Honda Motor Company Limited, et al., Case No. 5:20-cv-00666-MHH . Plaintiffs accuse Honda of deceptive trade practices, breach of warranty, negligent recall, and fraudulent omission .

2. Which Acura Models Are Affected?

The recall and lawsuit cover a wide range of Acura models from the 2013 through 2022 model years. Below is the full list of affected Acura vehicles:

Acura Models Included in the Fuel Pump Recall and Lawsuit:

  • 2016–2020 Acura ILX
  • 2013–2020 Acura MDX
  • 2018–2020 Acura MDX Hybrid
  • 2019–2020 Acura MDX Sport Hybrid
  • 2017–2020 Acura NSX
  • 2014, 2018–2020 Acura RDX
  • 2014–2015, 2018–2020 Acura RLX
  • 2019 Acura RLX Sport Hybrid
  • 2015–2020 Acura TLX

Additional vehicles covered by the settlement warranty extension (but not necessarily included in the original recall):

  • 2020–2022 Acura ILX
  • 2020–2022 Acura MDX
  • 2020–2022 Acura NSX
  • 2020–2022 Acura RDX
  • 2020 Acura RLX
  • 2020 Acura TLX

Honda says these additional vehicles are not considered defective, but they are still included in the class action settlement warranty extension .

3. The Recall Timeline: How This Problem Unfolded

The fuel pump issue did not happen overnight. It unfolded over several years, with multiple recall expansions:

May 2020: American Honda issued its first recall, affecting approximately 140,000 vehicles in the U.S. and 1.4 million worldwide, primarily 2018–2019 models .

March 2021: Honda expanded the recall to include additional vehicle models and years, bringing the total to over 600,000 U.S. vehicles .

December 2023: Honda announced a third expansion, this time covering approximately 2.6 million 2017–2020 Honda and Acura vehicles in the United States .

2024: A separate recall was issued for 2023–2025 Honda and Acura models involving a different fuel pump defect—high-pressure fuel pumps that could develop cracks and leak fuel, posing a fire risk .

As of July 2025, Honda has expanded the recall to over 2.5 million vehicles manufactured between 2017 and 2020, and the recall now covers 2018–2020 Honda Accord, 2018–2020 Honda Civic, 2018–2020 Honda CR-V, and many more .

4. What Causes the Fuel Pump to Fail?

The root cause of the defect is a manufacturing problem at Denso, the supplier. The fuel pump impeller is made of a plastic material that absorbs fuel over time. When the impeller absorbs too much fuel, it swells and deforms, causing it to interfere with the fuel pump body . This interference can:

  • Stop the pump from spinning altogether, cutting off fuel delivery to the engine
  • Create excessive friction, which can damage other internal components
  • Lead to sudden, complete failure with no warning

Honda has acknowledged receiving 583 warranty claims and 166 field reports related to this issue, though the company says it has received no reports of crashes or injuries .

5. What Does the Proposed Settlement Offer?

The proposed class action settlement, filed in early 2026, provides several benefits for Acura owners. However, keep in mind that the settlement is not yet final—a final approval hearing has not been scheduled as of the latest reports .

Here are the key benefits included in the proposed settlement:

1. Extended Fuel Pump Warranty
The settlement extends the warranty on fuel pumps to 15 years from the date the vehicle first went into service, or up to 150,000 miles, whichever comes first. This applies to both recalled vehicles that had their fuel pumps replaced and vehicles that were not recalled but are still covered by the settlement .

2. Free Fuel Pump Replacement
If your vehicle is covered, you can get the fuel pump replaced at no cost at an authorized Acura or Honda dealer. The dealer will replace the entire fuel pump assembly .

3. Loaner Vehicle and Towing
While the fuel pump is being replaced, you can request a free loaner vehicle. If your fuel pump is not working properly and your car cannot be driven, Honda will provide a tow to the dealership at no charge .

4. Reimbursement for Out-of-Pocket Expenses
If you have already paid for fuel pump repairs related to this defect, you can submit a claim for reimbursement. This includes costs for towing, rental cars, and diagnostic fees. There is no cap on reimbursements under the proposed settlement .

5. Coverage for Salvaged and Flood-Damaged Vehicles
It is important to note that the settlement specifically excludes "salvaged vehicles, inoperable vehicles, and vehicles with titles marked flood-damaged" from the limited warranty coverage .

6. What Is Not Covered by the Settlement?

While the settlement is broad, there are important limitations:

  • Vehicles that have exceeded 150,000 miles may only receive a 90-day warranty extension, since the 15-year/150,000-mile warranty is based on whichever comes first .
  • Salvaged, inoperable, or flood-damaged vehicles are not eligible for the limited warranty .
  • Vehicles that are not part of the class (such as models outside the 2013–2022 range) are not covered.

7. How to Check If Your Acura Is Affected

You can determine if your specific vehicle is included in the recall or the settlement by using these methods:

Check your VIN online: Visit www.recalls.acura.com or www.recalls.honda.com and enter your 17-digit Vehicle Identification Number (VIN) .

Call Honda directly: You can call American Honda at (888) 234-2138 to speak with a customer service representative about your vehicle .

Look for a mailed notice: Honda has stated that it will notify owners in stages via mail, with initial notifications sent in early February 2024 .

Check your dealer service records: If you have had fuel pump work done, your dealer can confirm whether it was related to the recall.

8. What Should You Do If Your Acura Has a Faulty Fuel Pump?

If you suspect your Acura has a defective fuel pump, follow these steps:

Step 1: Stop driving the vehicle if possible. Driving with a failing fuel pump is dangerous because the engine can stall without warning, causing loss of power steering and braking .

Step 2: Schedule an appointment with an authorized Acura or Honda dealer. The recall repair is free, and the dealer will replace the fuel pump assembly at no cost .

Step 3: Request a loaner vehicle if you need transportation while the repair is being done. The settlement guarantees a loaner or rental car during the repair process .

Step 4: Keep all documentation including repair orders, receipts, and communication with the dealer. This will be important if you need to file a reimbursement claim or pursue a lemon law claim .

Step 5: Contact a lemon law attorney if you have had multiple repair attempts or if the vehicle has been in the shop for an extended period. Under California lemon law, for example, you may be entitled to a full refund or replacement vehicle if the defect cannot be repaired after a reasonable number of attempts .

9. Can You Join the Lawsuit?

Yes, if you own or lease an affected Acura vehicle, you are likely part of the class action. The class includes all current and former owners and lessees of the covered vehicles .

To participate in the settlement: You do not need to do anything active to join the class. If the settlement is finally approved, all eligible owners will automatically receive the benefits, including the extended warranty and free repairs .

To opt out of the settlement: If you wish to pursue your own individual lawsuit against Honda, you may have the option to exclude yourself from the class action. This must be done within the deadline specified in the settlement notice .

To file a claim for reimbursement: If you have already paid out-of-pocket for fuel pump repairs, you can submit a claim for reimbursement through the settlement administrator once the claim process is open .

10. What Is the Status of the Lawsuit?

As of the latest updates in 2026, the proposed settlement has been filed but has not yet received final approval from the judge. A final approval hearing has not been scheduled . The case is pending in the U.S. District Court for the Northern District of Alabama, North Eastern Division.

The plaintiffs' lawyers have requested $27.6 million in legal fees, which is separate from the benefits provided to class members . Once the court grants final approval, the settlement will become official, and benefits will begin to roll out to owners.

It is worth noting that this is the third major class action settlement involving Denso fuel pumps. Similar settlements have been reached with Toyota (estimated $287 million in economic relief) and Subaru (estimated $380 million in economic relief). The Honda/Denso litigation is ongoing .

11. Signs Your Fuel Pump May Be Failing

Even if your vehicle has not been recalled, you should watch for these warning signs of a failing fuel pump:

  • Check engine light with diagnostic trouble codes P0171 or P0174, which indicate an improper fuel-to-air mixture
  • A whining noise coming from the rear of the vehicle, near the fuel tank or back seat
  • Difficulty starting the engine
  • Engine hesitation or sputtering during acceleration
  • Sudden stalling while driving
  • Reduced engine power when climbing hills or carrying heavy loads

If you notice any of these symptoms, take your vehicle to an authorized Acura dealer immediately for inspection.

12. What About Lemon Law Claims?

If your Acura has been in the shop for fuel pump repairs multiple times and the problem persists, you may have a lemon law claim. In California, for example, you are entitled to a replacement vehicle or a full refund if the manufacturer cannot repair a substantial defect after a reasonable number of attempts .

To pursue a lemon law claim, you should:

  • Gather all repair records, including dates, descriptions of the problem, and how long the vehicle was in the shop
  • Keep a log of all communication with the dealership and Honda
  • Document any out-of-pocket expenses, including towing and rental car costs
  • Contact an experienced lemon law attorney as soon as possible

The statute of limitations for lemon law claims varies by state. In California, consumers generally have up to four years from the date of delivery to file a claim, though recent changes may extend or shorten this deadline depending on the specific circumstances .
