I am glad to report that I received great news from the Lexus service manager regarding the problem with cycling noise at 70 mph that is outline in my previous posts (Jan 21, 2004_ 04'GX problem) is about to be resolved. He informed me that lexus is officially going to put out a memo out on the 20th of this month to all their dealers and provide part numbers and a fix to this issue.
He could not elaborate on what is going to be done on the car, but he said that he will read the memo to me once it is available. I can tell you that once the problem is fixed I can really start to enjoy my new car that I like a lot.
Will keep everyone posted.
