I've done the search to no avail...This question may not have been raised as most of the 2IS owners have fairly low mileage. Can anyone personally recommend an ideal time to change the belt?
Thanks in advance,

As several members who've encountered engine damage from broken valve springs can attest, this is not true.

Someone had a chain failure and bent valves or damaged pistons? I have never read of this happening.

Haven't heard about chain breakage, but broken valve springs have caused problems for some owners.

Not true, Koz. A broken valve spring will not retract the affected valve out of the way, resulting in repeated valve-to-piston contact in an interference engine like ours. Bad news, though not nearly as bad as when a cam is holding the valve open on an engine with a broken timing belt, or a broken cam actuator, as happened to this poster who experienced $4400 in engine damage:https://www.clublexus.com/forums/5782892-post235.html
I'm not sure where you got the idea that our engine is a non-interference design, but you are definitely wrong on that point.
