My vehicle has been making noises on start-up and in time it makes the same knocking noise while idling. I brought my car to my mechanic and he says it-??s my VVTI system failing and should be remedied under campaign 13V395000. The problem is holding Lexus accountable since it-??s not an open recall under my VIN. I-??ve contacted Lexus directly and confirmed this service was not completed. My VIN is listed on your site as being a potential for this issue. Please help, thanks.

Oil consumption, I have to add 2 quarts every 1300 miles

Because of the design, the rings stick causing oil consumption and engine wear. It smokes when driven. This affects these vehicles approximately years 06 - 11. They revamped the engine after 11 to fix the problem. They should repair our engines

Low oil light came on 1000 miles after oil change at Lexus dealership. Car was low 2.5 quarts of oil. Blue grey smoke was coming out of the car during acceleration and car smelled like poison inside very unsafe. Car has been dealer maintained for everything. Car was certified pre owned as well. At 100,000 miles oil consumption test was done and was in fact proved to be burning oil. Car is burning way too much oil. I've had 4 other vehicles none have burned oil. This is unacceptable and I might have to buy a new engine soon. Please help me out. Thank you.
