Diagnosing what’s wrong with a car in this situation isn’t easy, but if your Kia Soul won’t start and doesn’t click, it could be due to a bad starter solenoid or faulty ignition switch. A starter solenoid is an electromagnet that’s necessary to start the vehicle, while the ignition switch is a control system that activates the electrical systems of the Soul.
When these parts go bad, they won’t work at all, which is why you aren’t hearing any clicking noises when trying to start the car. Only a trained mechanic can tell for certain, but that certainly could be the problem.
The cost to replace the ignition switch on a Kia Soul is around $200 while the price of a new starter solenoid is around $450, including labor.
