Common Causes of Clicking Noise When Starting Subaru Crosstrek
A clicking noise when trying to start a Subaru Crosstrek often points to specific mechanical or electrical problems within the vehicle. These issues usually prevent the engine from cranking properly. Understanding the main causes can help identify the right solution quickly.
Weak or Dead Battery
A weak or dead battery is the leading cause of a clicking noise when starting a Subaru Crosstrek. When the battery lacks enough charge, it cannot provide enough power to the starter motor. This results in rapid clicking sounds as the starter tries to engage but fails to turn the engine over.
Battery terminals that are corroded or loose can also reduce electrical flow. Cleaning or tightening the battery connections often fixes this problem. If the battery is old or severely drained, it may need to be recharged or replaced. Checking the battery voltage with a multimeter can confirm its condition.
Faulty Starter Motor
The starter motor is responsible for turning the engine’s flywheel to start combustion. When this component is faulty, it often causes clicking noises during startup. The most common problems are worn gears inside the starter or a misalignment with the flywheel.
A faulty starter motor may fail to engage fully or only engage intermittently. This makes the clicking sound noticeable but prevents the engine from starting. In some cases, the starter motor can be repaired. However, replacement is usually necessary if the damage is severe or if the motor frequently fails.
Electrical System Issues
Electrical problems beyond the battery and starter motor can also cause clicking noises. Issues like blown fuses, faulty relays, or wiring problems may interrupt the circuit needed to start the engine. A blocked or damaged fuel system can sometimes cause similar symptoms but is less common.
Diagnosing electrical issues requires checking the fuses and relays related to the starting system. Loose or damaged wiring near the battery, starter, or ignition switch should be inspected. Repairing or replacing faulty electrical components restores proper current flow and solves the clicking noise problem.
Diagnosing Clicking Sounds During Startup
When a Subaru Crosstrek makes clicking noises while starting, it is important to focus on how the sound occurs and inspect key engine parts. These steps help identify if the issue is electrical, mechanical, or related to battery health. Clear observation can speed up fixing the problem.
Listening for Single vs. Rapid Clicks
The pattern of clicking sounds can reveal the underlying issue. A single click often means the starter motor solenoid is trying to work but can’t engage the engine crank. This usually points to a weak battery or poor electrical contact.
In contrast, rapid clicking sounds occur when the starter tries repeatedly to engage but is prevented by low voltage. This might suggest a very weak or discharged battery. Sometimes corrosion on battery terminals causes similar effects by blocking power flow.
Pay attention to whether dashboard lights dim during clicking. Dimming lights with rapid clicks almost always signal battery or connection problems. Understanding these patterns helps narrow down the cause without guesswork.
Visual Inspection of Engine Components
A quick visual check can identify obvious issues. First, examine the battery terminals for corrosion or loose connections. White or green buildup means electricity may not flow well, needing cleaning or tightening.
Next, inspect the starter motor and related wiring. Look for damaged cables or signs of wear. Any frayed wires or loose mounts should be fixed before testing starts again.
Also, check the engine for leaks or broken parts near the starter. Damage in this area can block the gear from turning. If no physical damage shows but the problem persists, the starter motor itself may need professional testing or replacement.
This hands-on check reveals many common causes of clicking sounds during startup.
Battery and Electrical Connections
The Subaru Crosstrek’s clicking noise when starting often links to issues with the battery and electrical connections. Problems here can prevent enough power from reaching the starter motor, causing the rapid clicking sound without engine cranking. Proper inspection and maintenance of these components are essential to address the issue effectively.
Corroded Battery Terminals
Corrosion on the battery terminals is a common cause of starting problems. Over time, acid residue and dirt can build up, creating a poor electrical connection. This weakens the battery’s ability to transfer power to the starter motor.
When terminals are corroded, the electrical current faces resistance, which can cause the clicking noise during start attempts. It can also drain battery power even when the car is off. Cleaning the terminals with a wire brush or battery terminal cleaner and applying a protective coating can restore a strong connection.
Regular checks of terminal condition help prevent corrosion buildup. This simple step often fixes or avoids clicking noises when starting.
Loose or Damaged Wiring
Loose, damaged, or burnt wiring in the starting circuit can also cause clicking noises. If cables connecting the battery, starter, or ground are not secure, power flow is interrupted. This prevents the starter motor from fully engaging.
Damaged insulation or connectors may cause short circuits or poor electrical contact. Both lead to insufficient current for the bike’s starter. Repair or replacement of affected wiring is necessary.
Technicians often inspect wiring and connections with a multimeter or visual check. Ensuring all cables are firmly connected and intact removes a common cause of the clicking sound during startup.
Starter Motor and Solenoid Concerns

A clicking noise when starting a Subaru Crosstrek often points to problems with the starter motor or the solenoid. Issues can include worn parts inside the motor or failure in the solenoid’s function, both of which stop the engine from turning over properly.
Worn-Out Starter Motor
The starter motor is responsible for turning the engine over when the key is turned. Over time, the motor’s internal parts, such as brushes and the armature, can wear down. This wear causes weak or no engine cranking.
Signs of a worn starter motor include a rapid clicking sound or grinding noises. These sounds come from the motor struggling to engage or spin. Sometimes, it may hum but fail to turn the engine at all.
Testing the starter motor often involves bypassing the solenoid or checking electrical connections. If the starter motor is bad, replacing it is usually necessary to restore reliable starting.
Solenoid Engagement Issues
The solenoid plays two main roles: it pushes the starter gear to the flywheel and switches power to the starter motor. When the solenoid fails, it often produces a single click without starting the engine.
Poor electrical connections or corrosion at the solenoid’s terminals can cause it to malfunction. In some cases, the solenoid itself wears out or its contacts become weak.
A clicking noise paired with no engine crank often means the solenoid tried to engage but didn’t get enough power to complete the action. Cleaning the connections or replacing the solenoid can fix this problem.
Other Potential Mechanical Problems
Some issues causing clicking noises when starting a Subaru Crosstrek go beyond common electrical faults. These problems often involve key engine components or parts related to the ignition system, which need careful attention.
Seized Engine Parts
A seized engine can cause the starter to click rapidly while failing to turn the engine over. This happens when internal parts like pistons or crankshaft become stuck due to lack of lubrication, corrosion, or mechanical failure.
If the engine is seized, the starter motor struggles to rotate the engine, resulting in a repetitive clicking sound. This problem is serious and often requires professional inspection. Damage may include worn bearings or rusted components that prevent movement.
In some cases, the engine may seize due to overheating or the engine oil running too low. Checking oil levels and engine condition regularly helps prevent this. If seized parts are suspected, the vehicle should not be forced to start, as that can worsen the damage.
Ignition Switch Malfunctions

The ignition switch controls the power flow to the starter and other electrical components. A faulty ignition switch can cause intermittent clicking without starting the engine. It may fail to send a consistent signal to the starter motor.
Symptoms of an ignition switch problem include a clicking noise when turning the key, dim dashboard lights, or complete failure to start despite a good battery. This fault sometimes causes the security light or lock icon to flash on the dash.
Fixing an ignition switch requires testing the electrical connections for wear or corrosion. Replacing the switch often resolves the problem, restoring reliable power delivery to the starter circuit and eliminating the clicking noise.
Preventative Maintenance Tips for Subaru Crosstrek
Proper care of the electrical system and battery helps prevent clicking noises when starting a Subaru Crosstrek. Keeping these parts in good condition reduces the risk of starting problems. Regular checks and inspections can catch issues early before they cause failure.
Regular Battery Testing
The battery is often the first cause of clicking noises at startup. Testing the battery voltage and cold cranking amps (CCA) regularly ensures it can deliver enough power to the starter motor. Most batteries last around 3 to 5 years, but factors like weather and driving habits affect their lifespan.
A simple test can be done with a multimeter or at many auto shops. It is important to check the battery terminals for corrosion. Corrosion can block electrical flow, causing weak starts or clicking sounds. Cleaning the terminals with a battery terminal cleaner or baking soda solution helps maintain good contact.
Replacing a weak or old battery before it fails avoids being stranded. Some battery testers also assess the charging system, which helps detect alternator or wiring issues early.
Scheduled Electrical System Inspections
The electrical system includes the starter, alternator, wiring, and connections, all of which impact starting reliability. A scheduled inspection should check wiring for wear, loose connections, and signs of corrosion or damage.
Attention to the starter motor and solenoid is important because worn parts can cause the clicking noise without fully engaging the engine. Inspecting fuses and relays related to the starting system ensures no faults disrupt power flow.
Having a mechanic run a diagnostic scan can reveal hidden electrical faults. They can also perform a load test on the starter and alternator to verify proper functioning under demand.
Following a routine inspection schedule minimizes surprises and helps maintain the crisp start expected from a Subaru Crosstrek.
When to Seek Professional Help
If the Subaru Crosstrek makes a clicking noise when starting and simple fixes like jump-starting the battery do not work, it is time to consult a professional. Persistent clicking can point to problems beyond basic battery issues, such as a faulty starter motor or starter relay.
When the clicking noise is rapid, random, or accompanied by warning lights like a blinking red lock icon, this signals a deeper electrical or security system malfunction. These issues require specialized diagnostic tools and experience to identify the root cause.
It is important to avoid repeatedly trying to start the car under these conditions, as it can cause further damage. A mechanic will inspect key components including:
- Battery and terminals
- Starter motor and relay
- Ignition switch
- Electrical connections
If the problem stems from wiring faults or more complex electronic issues, a professional can safely perform repairs or replacements. Attempting these repairs without proper knowledge risks worsening the issue.
For peace of mind and to ensure the security features of the vehicle are intact, seeking expert help early is wise. Qualified technicians can provide a complete diagnosis and prevent more costly repairs in the future.
