When a Subaru Outback won't start and makes a clicking noise, it's often due to electrical issues. The most common culprit is a weak or dead battery. Other potential causes include corroded battery terminals, a faulty starter motor, or problems with the alternator.

Battery Issues

A weak or dead battery is the most frequent reason for clicking noises and failure to start. To check your battery:

  • Inspect the battery terminals for corrosion
  • Clean the terminals if necessary
  • Test the battery voltage with a multimeter (should read around 12V)
  • Try jump-starting the car

If jump-starting works, drive for about 30 minutes to recharge the battery. If the problem persists, you may need a new battery.

Starter Motor Problems

If the battery is fine, the starter motor could be the issue. Signs of a faulty starter include:

  • A single loud click when turning the key
  • Rapid clicking sounds
  • The engine not turning over

To troubleshoot, tap the starter motor gently with a hammer while someone tries to start the car. If it starts, the starter likely needs replacement.

Alternator Issues

A failing alternator can cause battery drain, leading to starting problems. Signs include:

  • Dimming headlights
  • Battery warning light on the dashboard
  • Electrical systems behaving erratically

Have your alternator tested if you suspect it's the problem.

Other Potential Causes

  • Corroded or loose battery cables
  • Faulty ignition switch
  • Blown fuses
  • Fuel system problems

Always check the simplest solutions first, like the battery and connections, before moving on to more complex issues.
