Asked by for the 2007 Lexus RX350
Does the Lexus RX350 have a timing belt that should be changed? I couldn't find it listed within their maintenance lists.

You can get this estimate and any others at www.repairpal.com/estimator and find a shop here www.repairpal.com/directory
If you do the job yourself it will cost you $40. If you take it to a shop $200+ and to a Lexus dealer over $300.
