I took my 2018 Honda Odyssey to the dealership for a fuel pump recall repair. The next day, the engine warning light turned on, and I heard a loud abnormal noise from the high-pressure fuel pump.I scheduled an immediate service appointment. The dealer charged me $230 for a diagnostic but claimed no fault or error code was found. They turned off the warning light without explaining why it was triggered.The abnormal noise from the high-pressure fuel pump persisted, and the dealer recommended replacing the high-pressure fuel pump for $1,942.78 while denying any connection to the recall repair. Component/System That Failed: High-Pressure Fuel Pump Engine Management System How Was Safety Put at Risk? A fuel system failure can cause engine stalling, leading to sudden loss of power while driving and an increased risk of a crash. Has the Problem Been Confirmed by a Dealer? Yes. The dealership acknowledged an abnormal noise from the high-pressure fuel pump but denied any connection to the recall. They only reported a DCA-8000 code, which is not a standard fuel system error code. Has the Vehicle Been Inspected by the Manufacturer? Yes. The dealership inspected the vehicle but refused to take responsibility. Honda Corporate was also contacted, but they denied warranty coverage. Any Warning Lamps or Symptoms Before the Failure? No prior issues before the recall repair. The engine warning light turned on the next day, and the abnormal noise from the high-pressure fuel pump began immediately after. Why This Needs to Be Investigated: The issue began right after the recall service, suggesting a possible defect. The dealer charged me $230 but failed to explain the warning light activation. If other vehicles experience this, it may indicate a recall defect. A fuel system failure can create serious safety risks for drivers and passengers. NHTSA must investigate whether the recall service contributed to high-pressure fuel pump failures, as this could pose a significant safety hazard.
