Thanks Mikey,

Is there any way I can receive a copy of that letter? Maybe it would help my "cause" when I have my RX dropped off at the dealership for diagnostics. Or, is there a web-site where I can download the same information/problem for our vehicles.

Thanks for your advice! This really helps!

 

You don't need the letter, The dealership is aware of this problem. They replaced at least 5 .engine a week, this is when I was with Parkplace Lexus of plano. Since you change your oil every 3k miles, I doubt this could be your problem. Let us know how turn out.

Here is a site that references the letter:

Double checked the letter from Lexus. There is indeed no mileage limitation. Thanks Mikey.

 

has anyone fixed this problem yet?
