While there are some cases where a failing starter motor doesn’t give you any hint of being worn out, there are also obvious signs that you need to have it replaced. If your starter is failing, then you may notice these signs:

1. Engine Cranking But Not Starting: You turn the key, and the engine cranks but doesn’t start. This could mean that your starter motor is failing. The starter motor is responsible for cranking the engine, and if it’s not working properly, the engine won’t start.

2. Clicking Sound When Turning the Key: If you hear a clicking sound when turning the key, it’s possible that there’s a problem with the starter motor. This clicking sound can be caused by a weak or dead battery, a faulty starter solenoid, or a worn-out starter motor.

3. Slow Cranking: When you turn the key and your engine cranks slowly, it’s a sign that your starter motor may be failing. This could be due to worn-out starter motor brushes, a weak battery, or a faulty starter solenoid.

4. Grinding Noise When Starting: If you hear a grinding noise when starting your engine, it could indicate a problem with the starter motor. This noise is often caused by a worn-out starter motor gear or a faulty starter solenoid.

5. Smell of Burning: If you smell burning when trying to start your engine, it could be a sign of a failing starter motor. This can be caused by an overheated starter motor due to prolonged cranking, which can result from a weak battery, a faulty starter solenoid, or worn-out starter motor brushes.
