Hi, I have Lexus isf 300 for 3 days. From the first day I got it. I have unusual noise in my engine. I never had this kind of a car but it's my third lease. First one was a g37 ufter it, I had es350 non of them had this noise. Plus every time when I make full turn doesn't meter left or right it makes and u can feel some kind of vibration. By the way it sounds inside just like Diesel engine.
