Does my car stop working because its old? Strictly speaking no, there will be a cause of failure, in practice everything wears out, age has increased the chances of things wearing out, so after a certain point age becomes a 'good enough' reason.

I suppose if you want to be pedantic, a common failure mode isn't actually 'correct'. A heart attack isn't the cause of death, its oxygen starvation, so I'm not sure more 'correct' equals more useful.
