What owners report most
Engine
“My 2011 Lexus RX350 was running fine as I ran errands for groceries and other items around town one day. Then, out of the blue, I realized that after returning home and parking in my garage, there was a trail of oil in my driveway, leading to my vehicle. I looked under the engine area and noticed a pool of oil. I had a certified mobile mechanic come to my home and provide a diagnosis. This diagnosis was that a hole had formed in the rubber Engine Oil Cooler Line, and drained nearly all the oil in my engine. He mentioned that one more mile and I could have had total engine failure. He proceeded to replace it with a new Genuine Lexus, all metal Oil Cooler Line. I contacted Lexus about this incident, but they provided no compensation for this occurrence, even though there was a short 4-year technical service bulletin they issued barely a year after production, that called out this was indeed a flaw in their design. After doing some research, I see this is a VERY common issue, with many in the past most recent years having this very issue. Yet, Lexus has not recalled this, nor reimbursed those that have suffered from this manufacture defect. I am really hoping that…”
