The fuel pump sensor electrically shorted. The assembly failed. (tube assembly, fuel suction w/ pump and gage), gasket, fuel suction tube set. It is available for inspection. The car could stall at any time because the fuel pump sensor cannot accurately determine the fuel level or how much fuel is being injected into the engine. There was a warning light. Lexus covered two other fuel pump safety issues for this make and model (2018 RX 450h), one under a manufacturer recall and one through a customer support program. This is a THIRD defect with the fuel pumps on these vehicles for which Lexus has NOT offered coverage or notified its customers.
