TOYOTA IS RECALLING CERTAIN MODEL YEAR 2006 THROUGH 2008 LEXUS PASSENGER CARS MANUFACTURED FROM AUGUST 26, 2005 THROUGH AUGUST 4, 2008. MICRO-FOREIGN OBJECTS IN THE MATERIAL OF THE VALVE SPRING MAY DEGRADE THE STRENGTH OF THE VALVE SPRING, POSSIBLY CAUSING THE SPRING TO BREAK.

“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.”
“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…”
“We were crossing under the light to go to the gas station and we believe the car that hit us ran a red light. It caused right rear damage and side airbags to deploy. There's a metal piece in the tire and its undriveable.”
