As the service tech said, the condensor is the radiator-type device that sits in front of the radiator. Unfortunately, it will be the first item hit by a stone from a passing vehicle. I would guess that the repair cost from Lexus is about right. As others have said, this is something that just about any a/c shop can work on. A/c work is usually not cheap though. I don't believe that a condensor can be repaired at all. Just replaced.

I have heard horror stories of rock chips on the condenser....and the dealer will not accept it under warranty, rightfully so.

When I bought the RX, I immediately put on the mesh screen...to protect the condenser.....

It was just a bad design for the coil to be exposed to an area of high exposure to rocks from the road....

Hence the mesh...to protect the air dam opening....

 

Check this post I did more than a year ago....mesh on the air dam..

thank you guys for all 'ur info. it's been helpful for me to decide what's should
i do. My Rx is @ dealer now , they even showed to me the condenser leaking
coming from below opening of air vent by adding freon . The stimate cost is about $700 -1000.
Mandyfig> i might do Diy you suggest for condenser protection that will really help and save me $$, it maybe late for me but no more next time . My only
concern is , will it affect the air going to condenser/ radiator ?
