An official CAA Japan notice concerns Passenger car (Honda of America NSX) - Repair. Defect in the fuel system (low-pressure fuel pump). ■ Defective component: Fuel system (low-pressure fuel pump). ■ Nature and cause of the structure, equipment or performance deemed noncompliant with standards: In low-pressure fuel pumps installed in vehicles requiring unleaded premium gasoline, an unsuitable fluid used during pump operation testing may penetrate the impeller (resin rotor), reducing its strength and causing cracks. Repeated heating and cooling may then cause the cracks to spread and the impeller to swell due to fuel exposure, bringing it into contact with the pump cover and causing malfunction. In the worst case, the engine may stop while driving and become impossible to restart. Published 2026-05-28.
What to do now
(Recall) 外4194 ■ Corrective measures: Replace the low-pressure fuel pump module in all vehicles with an improved part.
