Hi, this is a great forum. My wife has a 99 RX300 with about 55K miles on it and so far it has been good. However, checking this forum and edmunds.com and my own experience have led me to conclude the following common problems:
1. Suspension noise/thud especially on the passenger front and back- This has happened to me and Lexus fixed it for free
2. The "D" indicator light on the instrucment panel blows out- happened to me as well
3. Leaking rear oil seal- has not happen to me
4. Oil gel and transmission failure- has not happen to me but I change my oil with Mobil 1 every 4K and flush the trans every 30K.
On the whole, it has been a good car but feel this kind of problem should not be happening with cars made by Lexus considering how much we paid.
