Timing chains are designed to last the life of the engine. Chain replacement would be done during a complete engine rebuild.
In 2010 Lexus RX350's started using Timing Chain's in the 3.5 engine, which require no maintenance (unless very high mileage is reached or parts failure). Earlier years <2009 had timing belts. I verified the 2010 model has a timing chain via contacting a local Lexus parts department.
It has a timing CHAIN
The 2009 Lexus RX350 is equipped with a timing chain rather than a timing belt. Timing chains are generally more durable and require less frequent maintenance than timing belts. However, it's still important to follow the manufacturer's maintenance schedule to ensure the longevity of the engine components.
