Why does my toilet randomly run for a few seconds?

The most common issue with toilets randomly flushing is that the flapper has become brittle or sediment has formed on the flapper/tank which prevents the flapper making a complete seal. If enough water is permitted to leak out of the tank, the filling mechanism will be triggered and the tank will refill.
