How do you know if a starter is going out?

A starter may be going out if your vehicle has difficulty starting, makes a clicking noise when you turn the key, or shows dimming lights or electrical issues when attempting to start. Additionally, if the engine fails to crank or starts intermittently, it could indicate a failing starter. It's also helpful to check for any unusual smells or signs of wear around the starter itself. If these symptoms persist, it's advisable to have the starter tested or replaced.
