Denso recalls 3.5m fuel pumps for possible failure

Michigan, Detroit – Denso North America is recalling more than 3.5 million fuel pumps due to a defect that may cause the fuel pumps to stop working, potentially causing a stall or risking a crash.

In an April recall report filed with NHTSA, the Japanese auto parts supplier flagged more than 2 million fuel pumps because "an impeller in some low-pressure fuel pumps may become deformed under certain conditions, which could render the fuel pump inoperable."

In its latest recall report 17 Nov, the company added more than 1.5 million fuel pumps to the earlier recall, bringing the total up to about 3.53 million units. 

Automakers that have purchased the defective parts for possible use or installation in their vehicles include Honda, Ford, Subaru, Toyota and Mitsubishi. 

Last month, Toyota added 1.5 million Toyota and Lexus vehicles to a large recall announced in January over fuel pumps manufactured by Denso. 

In total, about 3.34 million Toyota vehicles are now included in the recall, covering model years 2013 to 2020.

In a statement to ERJ US sister publication Automotive News, a spokeswoman for Denso said the low-pressure fuel pumps impellers could, under certain conditions, absorb fuel.

This, she said, “could lead to reduced operability of the fuel pump."
