Defect	In low-pressure fuel pumps installed in vehicles specified for unleaded premium gasoline, an inappropriate inspection fluid used during pump operation inspection may penetrate the impeller (resin impeller), reducing its strength and causing cracks. As a result, repeated heating and cooling may cause the impeller cracks to progress, swell due to fuel, come into contact with the pump cover, leading to malfunction. In the worst case, the engine may stop while driving and become unable to restart.
Component	Fuel system (low-pressure fuel pump)
Remedy	For all affected vehicles, the low-pressure fuel pump module will be replaced with an improved part.
