Amusingly, my 1995 Saturn had a timing chain, and the chain skipped a tooth on its last day, at roughly 60k miles. Now, there wasn't necessarily anything wrong with the chain per se but it was the end of a sequence of failures involving the engine design. On all of our other cars (Toyota), the belts needed to be serviced at X miles, but it was actually a cheap and quick procedure.
