Honda Fuel Pump Lawsuit: What Every Owner Must Know About the $27.6 Million Settlement and Your Rights

If you own or lease a Honda or Acura vehicle from the 2013–2023 model years, here is the bottom line: a massive class action lawsuit has been settled, covering approximately 6.2 million vehicles in the United States due to defective Denso-manufactured fuel pumps that can cause your engine to stall or fail to start unexpectedly . The settlement extends your fuel pump warranty to 15 years or 150,000 miles, offers reimbursement for out-of-pocket repairs, and provides free loaner vehicles while repairs are done . You do not need to take any action right now, but you should understand what is covered and how to claim your benefits.

What Went Wrong with the Honda Fuel Pump

The defect is not in the entire fuel pump assembly — it is a single plastic part inside the pump called the impeller. This small spinning disc is responsible for moving fuel from the tank to the engine. According to NHTSA recall documents, the impellers in Denso-made low-pressure fuel pumps were improperly molded, producing material that was less dense than it should have been . When exposed to fuel over time, the low-density impeller absorbs liquid and swells, eventually deforming enough to scrape against the pump body. That friction can jam the pump entirely, cutting off the engine’s fuel supply .

For drivers, the failure can show up as:

• A check-engine light
• Rough running or hesitation during acceleration
• Difficulty starting the engine
• Intermittent power loss
• A full stall while driving — the most dangerous symptom

The stalling risk is the core safety concern: a vehicle that suddenly loses power while merging onto a highway or crossing an intersection puts its occupants and other road users in danger. Honda has stated it received no reports of crashes or injuries tied to the defect as of December 2023 .

The Recalls That Led to the Lawsuit

Honda issued a series of overlapping recalls before the class action settlement was proposed:

1. NHTSA Campaign 20V-314 (May 2020): The first recall, covering early affected vehicles.
2. NHTSA Campaign 21V-215 (March 2021): Expanded the recall to approximately 624,552 additional vehicles .
3. NHTSA Campaign 23V-858 (December 2023): The largest recall, encompassing about 2.54 million vehicles .

Honda reported 4,042 warranty claims related to the defect as of December 2023, but zero injuries or fatalities . The recall remedy itself was straightforward: dealers would replace the fuel pump module with an improved version featuring a denser impeller and more clearance inside the housing. However, the rollout was slowed by a shortage of replacement parts, so owner notifications went out in stages beginning in early February 2024 .

That delay, combined with thousands of owners who had already paid for repairs before the recalls were announced, helped set the stage for class action litigation.

The Class Action Lawsuit: Oliver v. American Honda Motor Co.

The lawsuit was filed by plaintiff Tucker Oliver in the U.S. District Court for the Northern District of Alabama (Case No. 5:20-cv-00666) . The case was consolidated with other similar lawsuits alleging the same defect. After six years of litigation, a proposed settlement was reached in 2026 .

Key Settlement Terms

What the Settlement Means for You

Warranty Extension: The most immediate benefit is that Honda will extend warranty coverage for the affected fuel pumps to 15 years or 150,000 miles, whichever comes first . If your vehicle is already outside that time or mileage limit, you still have a 90-day window after final approval to get your pump replaced at no cost . Replacement pumps installed during that period will be covered by a one-year warranty.

Reimbursement for Out-of-Pocket Costs: If you already paid for fuel pump repairs before the settlement’s final approval, you are eligible for reimbursement . This is a significant benefit for owners who did not wait for the recall and paid out of pocket.

Free Loaner Vehicles: One of the most practical features of this settlement is that Honda will provide free loaner vehicles to class members who need transportation while their vehicles are undergoing fuel pump repairs under the extended warranty . Fuel pump replacements can take a full day or more, and this eliminates the hidden cost of rental cars.

Which Vehicles Are Covered

The affected lineup spans most of Honda’s and Acura’s 2013–2023 passenger vehicle range. Here is the full list:

Honda Vehicles

• 2013–2023 Accord (2-Door and 4-Door)
• 2017–2020 Accord Hybrid
• 2016–2021 Civic (2-Door, 4-Door, Hatchback, Type R)
• 2018–2019 Clarity Plug-in Hybrid
• 2013–2023 CR-V
• 2020 CR-V Hybrid

• 2019 Acura RLX Sport Hybrid
• 2015–2020 Acura TLX

Important note: Some vehicles included in the settlement were not part of the original recalls because Honda maintains they are not equipped with defective fuel pumps. However, they are still covered under the settlement terms .

What You Should Do Now

1. Check Your Vehicle Identification Number (VIN): Go to the NHTSA recall portal or Honda’s owner website to see if your VIN is included in the settlement.
2. Keep Your Records: If you already paid for a fuel pump repair, keep all receipts and documentation. You will need them to file for reimbursement.
3. Monitor for Updates: The settlement is pending final approval by the court. Once approved, Honda will send notifications to class members with instructions on how to claim benefits.
4. Schedule Repairs Promptly: If your vehicle is eligible, do not delay. The free replacement window under the extended warranty is limited, especially for vehicles already beyond the mileage limits.

Why This Settlement Matters

This is not a typical automotive class action settlement. Compared to most, the structure is more substantial. The 15-year/150,000-mile warranty extension is far longer than the standard powertrain warranty most owners have on their cars . The free loaner vehicle provision is also rare and addresses a practical pain point that owners often quietly absorb.

The settlement also highlights a broader industry problem. Similar agreements have been reached with Toyota and Mazda over the same Denso fuel pumps . A class action lawsuit has also been filed against Hyundai and Kia for alleged fuel system defects . It appears that almost all Japanese automakers that used the same Denso supplier in the late 2010s were affected by the initial pump problem.
