A clicking sound when you turn the key or press the start button can leave your Subaru Outback stranded. Searches for “Subaru Outback makes clicking noise and wont start” often describe a weak battery, a poor electrical connection, or a problem in the starting system.
The sound gives you a useful clue, but it does not identify the failed part by itself. This guide explains how to tell rapid clicking from a single click, check the battery and cables safely, try a jump-start, and decide when the car needs professional diagnosis.
Why “Subaru Outback Makes Clicking Noise and Wont Start” Happens
A starter needs strong electrical current to turn the engine. If the battery cannot supply enough power, or current cannot travel through a cable or connection, the starter may click without cranking the engine.
The clicking pattern can help narrow the cause. A rapid series of clicks often points to low voltage, while one solid click can mean the starter receives power but cannot turn the engine. Those clues are useful, but testing is needed before replacing parts.
| What You Hear | Common Possibilities | First Check |
|---|---|---|
| Rapid clicking | Weak battery, loose terminal, poor ground, or discharged battery | Inspect battery connections and test battery voltage |
| One click | Starter or solenoid fault, weak battery, or poor cable connection | Check battery condition and cable voltage drop |
| No click, no crank | Dead battery, blown fuse, ignition or start-control fault, or selector issue | Check lights, dashboard behavior, and gear position |
| Engine cranks normally but does not start | Fuel, ignition, sensor, or engine-management issue | Read diagnostic trouble codes and check fuel and spark |
These patterns are starting points, not diagnoses. A severely discharged battery can cause a single click, and a failing starter can make repeated clicks. Note what the lights and dashboard do while you try to start the car.
Check the Sound and Dashboard Before Testing
Before opening the hood, confirm what happens when you try to start the Outback. Make sure the car is in Park, set the parking brake, and switch off accessories such as the heater and headlights.
Turn the key or press the start button once, then pay attention to the sound and dashboard. Repeated attempts can drain a weak battery further, so stop if the engine does not crank after a few tries.
- Rapid clicks with dimming lights: The battery may be discharged, or a cable connection may have high resistance.
- One click with bright lights: The starter circuit or starter motor may need testing, though a weak battery remains possible.
- Lights barely turn on: Check for a very low battery, loose terminal, or disconnected cable.
- Normal cranking without starting: The issue probably involves a different system than the starter circuit.
- Security or key warning: Try a spare key if available and check the owner’s manual for the immobilizer procedure.
Also check whether the gear selector sits fully in Park. If the car is an automatic, try starting it in Neutral while holding the brake. If it starts in Neutral but not Park, the selector switch or adjustment may need attention.
For a push-button Outback, follow the owner’s manual instructions for starting when the key fob battery is low. The backup method varies by model year, so do not assume every generation uses the same procedure.
Inspect the Battery and Its Connections
The battery is the best first place to investigate because it supplies the current needed to operate the starter. A battery can lose charge after a light stays on, a long period of storage, cold weather, or a charging-system problem.
Park on a level surface, switch the ignition off, and keep metal tools away from both battery terminals at once. Do not test or charge a battery that looks cracked, swollen, leaking, or frozen. Ask for professional help if you see those signs.
Look for Loose or Corroded Terminals
Check that the battery clamps sit firmly on the posts and that the cables show no damage. White, blue, or green buildup can interfere with current flow, even when the battery itself still holds a charge.
Do not twist or pull hard on a cable to test it. If a terminal moves by hand, feels damaged, or has heavy corrosion, have it cleaned and tightened using the correct procedure. Disconnecting a battery can reset vehicle settings, so check your owner’s manual first.
Measure Battery Voltage
A digital multimeter can give a quick reading across the battery posts with the engine off. A fully charged conventional 12-volt lead-acid battery often measures about 12.6 volts at rest, while a much lower reading can indicate low charge. Battery type, temperature, and recent charging affect the result.
A resting voltage reading cannot prove that the battery can deliver enough current to crank the engine. A shop or parts retailer can perform a load or conductance test, which checks battery performance under demand. Ask for the test result, not just a visual opinion.
If the battery repeatedly goes flat, replacing it may not solve the cause. The alternator, a loose connection, or an electrical draw while the car is parked may be draining it. A charging-system and parasitic-draw test can identify those problems.
Try a Jump-Start Only If It Is Safe
A jump-start can help if the battery has discharged and the vehicle has no other fault. Use the jump-start points and sequence described in the owner’s manual for your Outback’s model year. Subaru procedures can differ, and the manual takes priority over general instructions.
Do not jump-start a battery that is damaged, leaking, or frozen. Keep the vehicles from touching, switch off both ignitions before connecting cables, and keep loose clothing and cables clear of moving engine parts.
- Park the donor vehicle close enough for the cables to reach, but do not let the vehicles touch. Set both parking brakes and switch off accessories.
- Connect the positive cable to the positive terminal or designated positive jump point on the Outback, then connect its other end to the donor vehicle’s positive terminal.
- Connect the negative cable to the donor battery’s negative terminal. Attach the final negative clamp to the Outback’s designated ground point, not to a random painted or moving part.
- Start the donor vehicle if its manual allows it, then wait briefly. Try to start the Outback without repeatedly cranking for long periods.
- After the Outback starts, remove the cables in the reverse order, keeping clamps apart. Follow the vehicle manuals for any model-specific steps.
If the Outback starts, leave it running in a safe place and arrange a battery and charging-system test. A short drive may not fully recharge a deeply discharged battery, and a car that stalls or displays a charging warning needs prompt attention.
If the car still clicks, stop trying. The battery may be too weak, the cable connections may be faulty, or the starter may not be working. Repeated attempts can overheat cables or further drain the battery.
Consider the Starter, Solenoid, and Ground Cables
The starter motor turns the engine during startup, and its solenoid helps engage the starter. A worn starter, damaged solenoid, or poor ground connection can produce a click without turning the engine.
A single click makes the starter circuit worth checking, especially if the battery passes a proper test and the terminals are clean and secure. However, replacing the starter based on sound alone can waste money. A technician should test the circuit before recommending a part.
Ground cables connect the battery and engine to the vehicle’s electrical system. Corrosion, looseness, or internal cable damage can limit current even when the cable looks intact. A voltage-drop test during a start attempt can help reveal resistance in the positive or ground side of the circuit.
Starter diagnosis may require access beneath the vehicle or near moving engine components. Do not crawl under a car supported only by a jack. If you lack the right equipment and safe lifting setup, leave this check to a qualified mechanic.
Check the Alternator and Other Charging Problems
The alternator replenishes battery charge while the engine runs. If it does not charge properly, the battery may become too weak to start the Outback after a drive or overnight parking.
A jump-start that gets the vehicle running does not prove the alternator works. A charging-system test checks whether the alternator and related wiring supply the correct output for that model. A battery warning light, dimming lights, or repeated low-battery episodes can support the need for testing.
A damaged belt or charging-system connection can also affect charging, depending on the model and configuration. Have a technician inspect the belt, wiring, and alternator if the battery repeatedly loses charge. Ask them to check for a key-off electrical draw if the charging system and battery both pass their tests.
When the Engine Cranks but Does Not Start
A clicking sound can occur before the engine starts, but the next diagnosis depends on whether the engine actually turns. If the starter cranks the engine at a normal speed and the engine still will not run, the battery and starter may not be the main problem.
Possible causes include a fuel-delivery fault, ignition problem, sensor failure, immobilizer issue, or engine-management fault. A scan tool can read diagnostic trouble codes, but a code identifies a system or condition, not always the part that failed.
Check the fuel level and look for warning lights, unusual smells, or recent repairs. If the vehicle cranks slowly, returns to clicking, or loses electrical power, go back to battery and cable checks. If it cranks normally, ask a repair shop to diagnose fuel, ignition, and control-system operation.
Know When to Call for Roadside Help
Call roadside assistance or arrange a tow if a safe jump-start does not work, the battery appears damaged, or the vehicle repeatedly fails to start. A tow is also the safer choice if the car sits in traffic, on a steep slope, or in an unsafe location.
Tell the technician what the Outback does: rapid clicking, one click, dim lights, or normal cranking. Share whether a jump-start changed the symptoms and whether the battery or alternator has been tested. These details can help the shop focus its diagnosis.
Ask the repair shop to test the battery, inspect the terminals and grounds, and measure the starter circuit before replacing parts. If those components pass, ask about charging-system output, electrical draw, and engine-management checks. A written test result makes it easier to understand the recommended repair.
How to Prevent Another No-Start
Routine checks can catch a weak battery or loose connection before the car leaves you stranded. Battery life varies with climate, driving patterns, and battery type, so rely on test results instead of a fixed replacement date.
- Ask for a battery test during regular service, especially before cold weather or a long trip.
- Keep battery terminals clean and secure, and have damaged cables repaired.
- Switch off lights and accessories when parking, and check that interior lights turn off.
- Investigate repeated slow starts instead of waiting for the battery to fail completely.
- Follow the maintenance schedule in the owner’s manual for your Outback’s year and engine.
If a new battery discharges again, request a charging-system and key-off current-draw test. Replacing batteries without finding the drain can leave the same no-start problem in place.
Getting a Subaru Outback Clicking and No-Start Problem Fixed
Rapid clicking often points to low battery voltage or a poor connection, while a single click can involve the starter circuit. Check the dashboard behavior, inspect the battery safely, and use the correct manual procedure if you try a jump-start.
Do not replace the starter or battery based on sound alone. A battery load test, cable voltage-drop test, and charging-system check can identify the actual cause and help prevent another breakdown.
Frequently Asked Questions
Can a Bad Battery Cause One Click Instead of Rapid Clicking?
Yes. A weak battery can sometimes produce one click, especially if it has just enough power to activate the starter solenoid but not enough to turn the engine. Battery voltage alone does not confirm battery health, so ask for a load or conductance test before replacing it.
Why Does My Outback Click After I Install a New Battery?
A new battery does not rule out a loose terminal, poor ground, defective battery, or starter problem. Check that the connections are secure and that the battery matches the vehicle’s requirements. If the connections look good, have a technician test the starter circuit and charging system.
Can Cold Weather Make My Subaru Outback Click and Fail to Start?
Cold temperatures can reduce a battery’s ability to deliver current, while the engine may need more effort to turn. A battery that worked in mild weather can struggle in cold conditions if it has lost capacity. Have it tested, and inspect the connections before winter travel.
Should I Keep Trying to Start My Outback If It Only Clicks?
No. Repeated start attempts can drain the battery further and may heat the starter or cables. Try only a few brief attempts, then check the battery and connections or call for assistance. Stop immediately if you notice smoke, a burning smell, sparks, or a damaged battery.
Will a Jump-Start Fix the Problem Permanently?
A jump-start can get the car running when the battery has lost charge, but it does not repair a failing battery, alternator, cable, or starter. If the Outback starts after a jump, have the battery and charging system tested. Repeated jump-starts call for a full diagnosis.
