I'm not sure about all SPD cleats, but mine do not. I can tell when mine need replacing because there is too much play between my shoe and the pedal. They also become harder to clip out of and can get noisy (squeaking or clicking).
In general, I just assume that my cleats will need replacing about once per year. I'd rather pay $20 for new cleats than deal with pedal issues that might be related to cleat wear.
ETA: Keep in mind that I ride A LOT. So once a year is probably more often than most.

My left (Speedplay X) cleat has to be replaced quite regularly, from unclipping. DH swears Imust drag my foot on the ground when I stop (I don't), but Ialways know when it's time, because I start have trouble clipping in, that no amount of lube can fix.

in addition to replacing cleats when needed, it also pays to check them visually often for grit or embeddedstuff which may affect your ability to clip in or out. From one who has had the experience and is just saying.
