There is a known issue in the form of a Warranty Policy Bulletin and I believe a recall in Canada for a faulty engine oil cooler line that was made of rubber and fails under heat (now replaced by metal lines). This happened to my daughter after a hot day and she pulled away from the driveway the next day. Almost all of the oil leaked out and we stopped the car and had it towed to a Lexus dealership. When it was inspected, it was confirmed this was the issue, and there was a noise in the engine. I have a concern that further engine problems may have resulted in a loose bearing needing compete replacement. This has yet to be confirmed, but seems consistent with the many discussion boards that mention this exact issue.

My rx450H ' check hybrid system' light came on while driving 70 mph on I95. Once the light came on I no longer was able to give my car any gas or accelerate and slowly my car started decreasing it's speed. Attempting to pull over to the side of the highway all my lights on my dash board came on and the car shut down. After turning off my car and letting it sit for a few minutes I was able to turn the car on and drive to the next exit. After having my car towed to a mechanic I was told they were unable to find anything wrong with the car. I picked up my car and it drove perfectly fine for about 2 weeks. Than it happened again. After the mechanics looked at my car again they determined that my fuel pump is needing to be replaced. I have read many stories of others with my same situation. I am curious as to why my year/make/model are not on the recall list for fuel pump replacement. The pump being recalled is the same make and model that is in my car.

RX 450h

  • 132,000 miles
Bought a used 2010 Lexus Rx 450H 3.5L with 130,000 miles. At approximately 132,000 miles while driving on the highway, oil cooler line suddenly exploded without warning and vehicle lost all of its oil, full synthetic, within seconds. Oil splattered all over entire underbody. Vehicle completely un-drivable and had to be towed. No pre warning from oil light or any other indication other than loud bang and smell of burning oil. Huge safety risk and likelihood of complete engine loss or seizing if I had continued to drive any longer, possibly leading to an accident or worse. Immediately pulled over at smell of hot oil and had it towed to repair shop. Estimated cost about $ 1,000. Repair shop stated this is a known issue with Toyota oil line cooler hose and Lexus models of this year and should have been a recall item. Recommended replacement hose is now metal.

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.

I was slowly entering from I15 to H-78 West. Suddenly car began to rev and accelerate as if I was flooring gas pedal. I jabbed at pedal a couple times and hit brakes...it stopped within a few seconds....not sure if what I did had anything to do with it stopping. My gas pedal is not sticky and smoothly adjusts. My vehicle is in pristine condition and has had all maintenance. I was fortunate I had several car lengths clear. I am 100% certain I did not accidentally slip or push on pedal. While it was accelerating I even lifted foot completely off pedal and it still was going.

The hybrid computer system shorted due to a leak where the roof rack connects to the roof. This computer is below the rear seat and is next to the hybrid batteries. This compartment should be sealed to prevent water intrusion, and in no situation should water from the roof be able to reach this compartment. Water entering this area is extremely dangerous and could cause a fire or the car to cease functioning correctly while it is in motion.
