What is it?
The starter motor essentially gets your car started. When you turn the key in your cars ignition, the engine then turns over and eventually cranks. When you turn the ignition switch, the starter motor is energized.
Why to get it repaired/checked?
If you find that one day you want to drive and your car won’t start up, a common problem could be from your starter motor. Any loud clicking noises when the ignition key is turned to the start position may suggest a problem with your starter motor which would require it to be brought in to be fixed or replaced.
