paulLS460

:( I have had the same issue twice between 7,000 and 10,000 miles. It has only happened twice so the dealer was unable to make it happen when I had the 10,000 mile check this week. The first time it happened the engine raced and the car lunged forward, requiring me to put both feet on the brake. The second time was not as severe, but nonetheless a little scary when it happened. The dealer told me the computer could find no abnormalities but I am concerned with safety. Maybe if enough have the problem we can get some action. Anyone else? I'm going to try to get more action from the dealer here. :(

I bought my LS 460 in August. I took it in for a 5,000 mile checkup with a problem of tapping noise in the engine during idle and very slow speeds. It does it when cold and when warm, after several hours of running so it is not just a cold start situation. The best way to describe the noise is like a diesel engine but not nearly as loud. The dealer did many tests, they heard the noise, called the factory and indicated to me that the factory is aware of the issue but has no fix as of yet. The report on my maintenance receipt is "This is a normal condition for this vehicle" Has anyone else had this issue or know if I am getting the real scoop? I know when I buy a luxury vehicle I don't expect this kind of issue (This is my first Lexus). It took several thousand miles of use to show up. Any help would be appreciated.
