I wasn't able to find specifically fires caused by electric stoves. Most are caused by faulty wiring, lights, and space heaters.
My assumption, stoves are not often involved in electric fires. They have isolated, grounded circuits that you aren't frequently plugging and unplugging into. The thinker cables usually have thicker insulation on top of that.
Also, contemporary induction stoves don't actually get "hot", at least for a stove top. They do have quite a lot of electricity flowing, however, so shorts etc. could potentially be bad. They seem rather unlikely, however.
