Your Subaru Crosstrek won’t start. What should you do next?
First, don’t panic. There are several reasons your Crosstrek might not start. Identifying the issue can save time and money. The Subaru Crosstrek is a reliable vehicle, but like any car, it can face issues. Understanding the common causes of starting problems can help you troubleshoot.
Sometimes, the fix is simple, like a dead battery or a loose connection. Other times, it might require professional help. This guide will walk you through the potential problems and solutions. So, let’s dive in and get your Crosstrek running again.
Common Causes
Is your Subaru Crosstrek not starting? There are several common causes. Knowing these can help you identify and fix the issue quickly. Below, we discuss some of the most frequent reasons your Crosstrek won’t start.
Battery Issues
The most common cause is a dead battery. A dead battery can be due to leaving lights on, an old battery, or extreme weather. To check, look for dim lights on the dashboard. If they are dim, the battery is likely the issue.
| Signs of Battery Issues | Possible Solutions |
|---|---|
| Dim dashboard lights | Charge or replace battery |
| No response when turning the key | Jump start the car |
| Corroded battery terminals | Clean terminals with a brush |
Starter Motor Problems
The starter motor turns the engine over. If it fails, the engine won’t start. Listen for a clicking sound when you turn the key. A clicking sound often means a bad starter motor.
- Check the starter motor connections.
- If connections are good, the starter motor might need replacing.
Ignition Switch Failures
The ignition switch sends power to the starter. If it fails, the car won’t start. Signs of a bad ignition switch include:
- No noise when turning the key.
- Accessories not working (radio, lights).
If the ignition switch is faulty, it will need to be replaced. A mechanic can diagnose and fix this issue.

Battery Check
Your Subaru Crosstrek won’t start, and you’re stuck. One common issue is the battery. Checking the battery is crucial. Let’s dive into the steps you need to follow.
Testing Voltage
First, you need to test the voltage. Use a multimeter for this task. Set the multimeter to 20 volts DC. Connect the red probe to the positive terminal. Connect the black probe to the negative terminal. The reading should be around 12.6 volts. Anything below 12 volts means a weak battery.
Inspecting Terminals
Next, inspect the terminals. Corroded terminals can cause starting issues. Look for white or blue powder on the terminals. If you find any, clean it off. Use a mixture of baking soda and water. Apply it with a toothbrush. Dry the terminals with a cloth.
Jump Starting
If the battery is weak, try jump starting. You need jumper cables and another car. Connect the red cable to the positive terminal of the dead battery. Connect the other end to the positive terminal of the good battery. Connect the black cable to the negative terminal of the good battery. Connect the other end to a metal part of the dead car. Start the car with the good battery. Wait a few minutes. Try starting your Crosstrek. If it starts, let it run for a while.
By following these steps, you can identify and solve battery issues. Ensure your Crosstrek is ready to go.
Starter Motor Analysis
The starter motor is crucial for your Subaru Crosstrek. It helps get the engine running. If your Crosstrek won’t start, the starter motor might be the issue. Let’s dig into the starter motor analysis.
Listening For Clicks
Turn the key in the ignition. Listen closely. Do you hear a clicking sound? This click usually means the starter motor is getting power. But it might not have enough juice to turn the engine over. If there is no click, the starter motor might be dead.
Tapping The Starter
Locate the starter motor under the hood. Use a small hammer. Gently tap the starter. Sometimes, this can help the starter motor work. It can temporarily fix stuck parts inside the motor. Try starting the car again after tapping.
Inspecting Connections
Check the connections to the starter motor. Look for any loose wires. Corroded connections can also cause problems. Clean the connectors if needed. Make sure everything is tight and secure. This can help restore power to the starter motor.

Ignition System
The ignition system is crucial for starting your Subaru Crosstrek. It initiates the engine’s combustion process. If the ignition system fails, your car won’t start. This section will cover common ignition issues.
Key Fob Issues
The key fob sends a signal to the car’s ignition system. If the battery in the fob is dead, the car won’t start. Replace the fob battery regularly. Also, check for damage. A damaged fob may not send a proper signal.
Steering Lock
The steering lock is a security feature. It prevents the wheel from turning without the correct key. If the steering wheel is locked, the ignition won’t engage. Turn the wheel while turning the key. This should release the lock.
Ignition Coil Faults
The ignition coil transforms battery voltage. It sends the correct voltage to the spark plugs. A faulty coil can cause starting issues. Symptoms include backfiring and rough idling. Have a mechanic check the coils. Replacing them may solve the problem.
Fuel System
The fuel system in your Subaru Crosstrek plays a vital role. It ensures your engine gets the fuel it needs to run smoothly. When the Crosstrek won’t start, the fuel system is a common culprit. Let’s explore some possible issues.
Fuel Pump Failure
The fuel pump is essential for delivering fuel to the engine. If it fails, your Crosstrek won’t start. You might notice a whining noise from the fuel tank. This noise often means the pump is struggling.
Clogged Fuel Filter
A clogged fuel filter can block fuel flow to the engine. This can prevent your Crosstrek from starting. Over time, dirt and debris build up in the filter. Regular maintenance can help avoid this issue.
Fuel Pressure Test
A fuel pressure test checks if the fuel system is working properly. Low pressure can indicate a problem with the pump or filter. You can use a fuel pressure gauge to perform this test. Ensure you follow safety guidelines during the process.
Electrical System
The Subaru Crosstrek is known for its reliability. But, like any vehicle, it can have issues. One common problem is the car not starting. Often, this is due to the electrical system. Understanding this system can help you diagnose the issue. Here are some common electrical problems that can cause your Subaru Crosstrek to not start.
Blown Fuses
Fuses protect your car’s electrical circuits. When they blow, the circuit breaks. This can stop your car from starting. Check the fuse box under the hood. Replace any blown fuses. Your car may start again.
Faulty Wiring
Wires connect your car’s electrical components. Over time, wires can become damaged. They might fray or break. This can lead to starting issues. Inspect the wiring in your car. Look for visible damage. Fixing the wiring can solve the problem.
Sensor Malfunctions
Sensors monitor your car’s systems. They send information to the car’s computer. If a sensor malfunctions, it can prevent the car from starting. Common sensors include the crankshaft and camshaft sensors. Check these sensors. Replace them if needed. This might get your Subaru Crosstrek running again.
Engine Mechanical Problems
One of the most common reasons why a Subaru Crosstrek won’t start is due to engine mechanical problems. These issues can range from minor to severe, and addressing them can often resolve the starting problem. This section will cover three major areas: Timing Belt Issues, Compression Problems, and Overheating.
Timing Belt Issues
The timing belt in your Subaru Crosstrek ensures that the engine’s valves open and close at the right times. If the timing belt is damaged, the engine may not start. Signs of a bad timing belt include:
- Engine misfires
- Ticking noise from the engine
- Visible wear on the belt
Replacing a worn timing belt can prevent further engine damage.
Compression Problems
Compression problems can also cause the engine to fail. The engine needs proper compression to start. Low compression can result from:
- Worn piston rings
- Blown head gasket
- Damaged cylinder walls
Using a compression tester can help diagnose these issues. Repairing any damaged parts can restore engine compression and functionality.
Overheating
Engine overheating can lead to significant damage, causing the engine to seize and fail. Common causes of overheating include:
- Low coolant levels
- Faulty radiator
- Malfunctioning thermostat
Maintaining proper coolant levels and ensuring the cooling system is in good condition can prevent overheating. Regular checks can save your engine from severe damage.
