Honda Recalls Large Number of Honda and Acura Vehicles for Potential Problem With Fuel Pump
Impellers used in these fuel pumps may fail due to a specific manufacturing process, potentially causing vehicle stall
Honda is recalling more than 600,000 Acura and Honda branded vehicles from the 2018-2020 model years due to a manufacturing problem with the fuel pump. The low-pressure fuel pump inside the fuel tank containing impellers produced during specific periods may fail. Honda has received 583 warranty claims and 166 field reports relating to this condition, but received no reports of injuries or crashes.
What's the problem?
Affected vehicles may be equipped with a fuel pump module manufactured with low density impellers. If the surface of a lower density impeller is exposed to production solvent drying for longer periods of time, higher levels of surface cracking may occur. These cracks may lead to excessive fuel absorption, resulting in impeller deformation. Over time, if an impeller deforms to a point that it creates sufficient interference with the fuel pump body, the fuel pump becomes inoperative, which may cause illumination of the Malfunction Indicator Lamp in the instrument panel. Fuel pump inoperability could prevent an engine from starting or stall an engine while driving, increasing the risk of a crash.
Honda conducted further analysis on impeller density to improve accuracy of the criteria used to determine part toughness. Honda found that the composition of non-resin material (glass fiber and calcium carbonate) in the impeller was highly variable, which led to high variance in impeller density measurements. To minimize variation, the non-resin material was removed with heat application, and the remaining resin material was measured to determine resin density.
