Oil cooler high pressure line, rubber elbow, pin hole oil leak/spray. TSB: POL.14.02 (the federal safety agency: 10056509). Leaked oil out with check engine light/low oil pressure warning just as I arrived home. Line of oil in driveway. Diagnosed leak from this rubber elbow. One quart of oil left in oil pan. After review of the federal safety agency website (and many, many Google hits) found this to be a well known problen by Lexus. No recall ever issued. I never received written notice from Lexus, and dealership that vehicle has been to many times never mentioned anything. Lexus denies any extended warranty at this time. Absolutely unacceptable.

Noticed a check engine light and slip indicator on - next day my car lost complete power in the middle of a city road ' vehicle was traveling about 15-20 MPH. When attempting to restart it would roughly engage then shut down again. Contacted a certified local lexus mechanic had the car towed to his shop. After assessment he determined the vehicle's fuel pump "disintegrated" internally. When they checked fuel pressure at the rail there were particles in the fuel ' upon further inspection the sparks plug were fouled and fuel injectors clogged. The mechanic indicated he had recently seen the same issue a month earlier however with a toyota fj. I began to research what happened when I ran across the fuel pump recall issued by toyota for certain models (january 2020) https://pressroom.toyota.com/toyota-is-conducting-a-safety-recall-involving-certain-toyota-and-lexus-vehicles-2/ although my model is not included in this recall my vehicle mimics the behavior of those recalled. Indicator lights, loss of power and ultimately an assessment of fuel pump issues leading to a total loss of power.

Major oil leaking from a faulty engine oil cooler line while car is moving or turned on. Oil is all over entire undercarriage, back bumper, back windshield & wiper and inside of tires. Garage floor and driveway have oil splattered everywhere. The whole back of car is cover in oil. After researching, I found this is a known issue for lexus rx 350/450h models between 2009-2011. No oil or engine warning light came on. Even after the faulty part is repaired, my concern then becomes potential engine failure from lack of oil.
