Denso Fuel Pump Defect Class Action

CONSUMER LAW GROUP has launched a class action lawsuit against Denso, Honda, Subaru, and Toyota on behalf of individuals who owned and/or leased a defective vehicle that uses the Denso low-pressure fuel pumps and fuel pump assemblies.

A defect in the DENSO fuel pump installed in the affected Honda and Acura vehicles leaves vehicle owners at risk of spontaneous vehicle shutdown, engine stall and other safety risks that increase the likelihood of a crash or injury.

The low-pressure fuel pump is an integral component of safe vehicle operation, and the affected vehicles suffer from a fundamental design flaw that causes the fuel pump to prematurely fail. The impeller in their low-pressure fuel pump absorbs fuel and water, causing it to degrade and deform. The deformed impeller comes in contact with the fuel pump body, creating excess running resistance, causing “illumination of check engine and master warning indicators, rough engine running, engine no start and/or vehicle stall[ing]...” according to reports.

When the fuel pump fails, gasoline is not supplied to the engine, causing reduced engine power, stalling, and/or engine shutdown. Compounding the problem, the fuel pump defect occurs spontaneously with no advance warning to the consumer, thereby creating an extremely dangerous condition for drivers and occupants.
