The timing chain only needs to be replaced if it becomes loose (You would hear a clicking noise under the hood when the engine is running) have that noise inspected right away if you hear it and it may need a timing chain. But not for a very very long time. Around 150,000-200,000 miles most likely.

The 2009 Mazda 3 MPS (Mazdaspeed 3) is equipped with a timing chain, which generally does not require regular replacement like a timing belt.
