Service brakes

“1. At [XXX] on [XXX], I was pulling into my gym's parking lot, when I stepped on the break to park my car, instead of stopping, the car accelerates rapidly and crashed through the other side of the sidewalk where there were light pole and cement walls, throwing me forward and backward with seat belt on, I was in total shock! 2. My insurance sent a field inspector to the body shop 2X in hope to repair my car but ended up declaring it a Total Loss. 3. Lexus said they would send a field tech to get the EDR (Event Data Recorder) data from my 2018 Lexus RX350 within 30 days, but the results won't be available for 30-45 days after that. Lexus's slow response to this accident concerns and disappoints me b/c it was a serious crash that Lexus should treat it seriously and promptly. 4. The disbelief of a 'young' car with only 12297 miles could have issues like this puzzled me and drove me to do a lot of online research, then I came across this site [XXX] which contains an article titled '10 Common Problems of A Lexus RX350'. Problem #5 described exactly what had happened to me: 'ONE RECURRING PROBLEM THIS CAR HAS IS THAT THE SYSTEM MALFUNCTIONS SEVERELY. THIS TYPICALLY…”

Fuel/propulsion system

8 reports
“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.”
