Honda Fuel Pump Issue Prompts Recall, Civic Type R and Acura NSX Also Affected

Inside the fuel tank of modern Honda models in the United States, there’s a low-pressure fuel pump that may feature a substandard impeller. This issue may prevent the engine from starting, and in the worst-case scenario, the powerplant may stall while driving.

Affecting 2018 to 2020 models, the safety recall is complemented by a stop-sale order for the Accord, Civic Hatchback and Civic Type R, the HR-V, Fit, and Insight. As the headline implies, Acura is also affected. The premium brand is calling back the RLX, RDX, as well as the NSX. The question is, how do those impellers fail?

Honda explains that the surface may be “exposed to production solvent drying for longer periods of time,” translating to surface cracking. In this condition, excessive fuel absorption may occur, leading to the deformation of the low-density impeller. Because of the swelling, a certain amount of interference may render the pump inoperative.

Instructions sent to U.S. dealerships reveal the extent of the repair, namely “replace the fuel pump motor with a properly manufactured part.” Emphasis on “properly.” The document also highlights that American customers will be notified by the end of July 2020.

“Honda received the first report of fuel pump module failure from the Indian market and an investigation was launched” according to the Part 573 safety recall report. The supplier analysis confirmed that swelling results in failure in May 2019, and in June 2019, the investigation “was elevated to the global Honda quality group for further handling.”

A total of 136,067 vehicles are “potentially involved” and the “estimated percentage with the defect” is 100 percent according to the document you can analyze below as a PDF. If you were wondering what supplier is to blame for this sub-standard part, that would be DENSO International America, Inc. of Southfield, Michigan.

If you own one of the aforementioned vehicles and you want to be sure yours is under recall, either get in touch with your local dealership or check the VIN on the NHTSA website.
