What is the most common cause of a failing starter in a Kia Picanto?

I have a Kia Picanto and it's been having trouble starting. I've tried charging the battery and checking the ignition switch, but nothing seems to be working. What could be causing this issue?

The most common cause of a failing starter in a Kia Picanto is a worn out solenoid or starter motor. It's important to have these components checked and replaced if necessary.

Another possible cause could be a faulty starter relay, which can prevent power from reaching the starter motor. Have a mechanic check this as well.

It's also possible that there is an issue with the wiring or connections to the starter. Make sure all connections are secure and have them tested by a professional if needed.

It could also be a problem with the ignition switch. If replacing the starter motor and solenoid doesn't solve the issue, have the switch checked and replaced if necessary.
