Engine Cranks but Won't Start or Hard to Start with Clicking Sound
The 2020 Jeep Grand Cherokee exhibits intermittent hard starting or no-start condition accompanied by a clicking sound. This typically indicates a weak battery, poor electrical connection, or a failing starter motor. The clicking is often the starter solenoid engaging but unable to crank the engine due to insufficient power.
Diagnosis Details
Possible Causes
Weak or discharged battery – voltage too low to crank the engine, often due to age, parasitic drain, or short trips.
Corroded or loose battery terminals/cables – poor electrical connection reduces current flow to the starter.
Failing starter motor or solenoid – worn brushes, bad solenoid contacts, or internal short causing intermittent operation.
Faulty ignition switch or starter relay – intermittent signal prevents starter engagement.
Engine mechanical issue (e.g., seized engine) – rare but possible if clicking is accompanied by no crank at all.
