There are 8 owner-reported fuel system complaints for the 2018 Lexus RXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.
Two days ago, upon entering our vehicle, there was a smell of gasoline as we drove. Our fuel guage wend from 1/4 tank to EMPTY in minutes. I pulled into a gas station and when attached the nozzle, gas entering the tank was POURING out from underneath. I drove the car to the venue we were headed to and parked on a dirt/gravel spot so as to limit fuel runoff to nearby vehicles. We had the vehicle towed to Bob Tyler Toyota, the nearest Lexus type service center. I called service at Lexus of Mobile and the employer stated that there are no recalls. The free flowing fuel endangered not only my and my wife but anyone around the vehicle. No warning lights whatsoever. The tow driver concurred that fuel was POURING until the tank was emptied. I have not been contacted by the service department thus far.
