Clicking Sound When Starting – Hard to Start or Won't Start
A clicking sound when trying to start the engine, especially on a 2020 Toyota RAV4, typically indicates a weak battery, poor electrical connection, or a failing starter motor. The issue occurs occasionally, suggesting an intermittent fault.
Diagnosis Details
Possible Causes
Weak or discharged battery – low voltage causes the starter solenoid to click but not engage the starter motor.
Corroded or loose battery terminals or ground connections – intermittent contact leads to occasional no-start with clicking.
Failing starter motor or solenoid – worn components may work sometimes but fail intermittently.
