[Katarin]

I see alot of used hybrid Lexus RX's....im thinking of 2012 or 2015 or 2009....any onfo on those?  

[RX400h]

Hello, Kathryn. Almost all or all Lexus hybrids have very good reliability ratings. The key when looking at used ones is knowing the maintenance schedule and verifying that all maintenance had been completed by the previous owner(s). Our RX400h is going on 19 years of age without any drivability issues during all those years. 
You should be able to find the maintenance schedules by doing a search. I would make an Excel spreadsheet with these (or similar) column or row headings:
Maintenance item
Mileage or time required
Actual date of completion
Shop or owner completing the service

You should also have the vehicle checked by a dealership or trusted independent shop.

Good luck with your search.
