Now that we're owners of an '05 RX330, what are some of the common problems people have found with this model? Are there any important TSB's that should be taken care of? Since it's under the Lexus certified pre-owned warranty, I want to make sure I catch everything and make it as close to new as possible. I don't know if the certification process would require some or all of the TSBs. Thanks.

 

Pay attention to condensation in the headlights. Eventually they all will have some. Mine didn't show up until 3 years later at around 48K miles, so furtunately I was still just within warranty.

 

You can get all TSIBs, shop manuals as well as other references from the Lexus/Toyota Technical Information System.

http://www.techinfo.lexus.com/

It is not free though, subscription access to TIS is offered in daily, monthly, or yearly intervals following the rate schedule noted below.
Daily $10.00 US
Monthly $50.00 US
Yearly $350.00 US

So for $10.00 you can spend a few hours downloading all the TSIBs for you car. If you are really ambitious you can spend a whole day downloading your shop manual in small chunks. The information you get is worth far more than $10.00 and will pay itself off rather quickly.
