Hola-
My oldest son is currently driving a 2010 CX-9 that belonged to my ex-wife and me. It has about 150k miles and has been pretty reliable for the most part. This car is probably going to be passed down to my youngest son when he turns 16. We'd like it to last another 2 years or so until he finishes high school. Obviously we don't want to spend unnecessary money, but is it a good idea to have the timing chain replaced? Thoughts on about how much the job would cost?
Thanks in advance for your help!
The timing chain, with proper oil changes, should last for the life of the engine and is not normally replaced without cause. A faulty chain or chain tensioner will normally set a CEL or at least start making noise. Also unlike a belt, it is uncommon for a chain to just break without the above warnings first. If there are no CEL and no unusual noise, just continue the routine engine maintenance not change it.

Timing chains last for the life of the engine unlike a timing belt.
