hey pmb, the wife's Maxima has 60K on it. The CPU registered an ignition problem, but it was intermittent. They replaced the coils (it apparently has separate ignition coils for each cylinder) and changed the belt (I know, I know). Regardless, I didn't want the wife and baby cruising in a faulty vehicle, y'know?
I still like the Maxima - it hasn't left us stranded anywhere - but in my experience with Japanese vehicles of all kinds, I have no more confidence in them than American vehicles.
