Kia Troubleshooting Questions? Ask a Mechanic
Hello, I'm Brandon - Kia tech.
Most likely the starter unit is bad. The starter solenoid is one whole unit that needs to be replaced.
It looks to me the battery is good. Just make sure the battery terminals are super tight.
If all is true , then yes the starter is the problem.
Let me know if you have further questions. Please rate me Positive, thank you!
