Morning all

I started my car this morning to hear a spinning noise, now the car started fine but I could hear a spinning fizzing noise is the only way to describe it.

It did this when i started the motor again at the petrol station but once I was at work i thought I'd test it and tried turning the ignition off and on again 4 times and the noise was not present, thinking it was cold start maybe.

Could this be a sign the starter motor is on its way out.

I couldn't understand it as it wasn't as if I was over turning the key to start the motor.

If anyone on here has heard of this before any advice on this would be greatly appreciated.
