I bought the car new and have had an engine noise from the beginning that sounds like a valve lifter. Lexus started out claiming no noise, then no abnormal noise, than piston slap and finally less than premium gas in the tank. I have all gas receipts and they're all premium. The NCDS (National Center for Dispute Settlement) funded by Toyota wasn't interested in the evidence disproving the Lexus claim. The noise had gotten worse and Lexus refuses to address the issue. The value of this car will be greatly diminished at trade in time.
Good looks, good power, great gas mileage.
Toyota needs to address this engine issue. Various dealers have told their customers that the noise was from fuel injectors, timing chains, and mine said piston slap and less than premium octane. This appears to be another Toyota cover-up.
