Engine Cranks but Won't Start - Clicking Sound
A 2020 Jeep Grand Cherokee that is hard to start or won't start with a clicking sound every time indicates a likely electrical or starting system issue. The clicking typically points to a weak battery, poor connection, or faulty starter.
Diagnosis Details
Possible Causes
Weak or discharged battery - insufficient voltage to engage the starter solenoid, causing rapid clicking.
Corroded or loose battery terminals/cables - poor electrical connection prevents full current flow.
Faulty starter motor or solenoid - internal failure causes clicking without engine rotation.
Parasitic drain or alternator failure - battery not being charged properly.

What You Should Do
Check battery voltage (should be 12.6V+).

Try jump-starting; if it starts, battery or charging system is likely weak.
If clicking persists with good battery, test starter and solenoid.
Inspect for corrosion at cables and ground connections.
