Subaru Forester Boot Not Opening? Causes and Fixes

Is your Subaru Forester boot not opening, even after pressing the button on your key fob or tailgate? This can be frustrating, especially when you have groceries, luggage, or other belongings stuck inside.

Fortunately, a Subaru Forester boot that won't open doesn't always mean an expensive repair. Sometimes, the problem is as simple as a weak battery, an electronic glitch, or a tailgate that needs resetting.

However, other cases involve a faulty boot latch, damaged wiring, or a malfunctioning power tailgate motor.

In this guide, we'll explain why your Subaru Forester boot won't open, how to troubleshoot the problem, and what you can do to fix it.

We'll also cover the emergency boot release, power tailgate reset procedure, and common issues affecting different Subaru Forester model years.

Why Is My Subaru Forester Boot Not Opening?

Several mechanical and electrical problems can prevent your Subaru Forester boot from opening.

The most common causes include:

• Weak or flat car battery: The electronic tailgate system may not receive enough power.
• Faulty boot latch: The locking mechanism may become jammed or fail electronically.
• Power tailgate malfunction: The automatic opening system may stop responding.
• Key fob problems: A weak battery or incorrect button operation can prevent remote opening.
• Blown fuse: A damaged fuse may interrupt power to the rear gate system.
• Damaged wiring: Electrical connections around the tailgate may deteriorate over time.
• Obstruction: Luggage, dirt, or debris may interfere with the latch.
• Tailgate calibration issue: The power rear gate may need to be reinitialised.
• Defective exterior release button: The switch near the number plate may stop working.
• Faulty tailgate struts: Worn supports may prevent the boot from lifting properly.

The correct solution depends on whether your Forester has a manual boot or an electric power tailgate.

Subaru Forester Boot Not Opening: Quick Fixes

Before investigating complicated electrical faults, try these simple troubleshooting steps.

These checks can help identify whether the problem is electrical, mechanical, or related to the vehicle's operating conditions.

1. Check If the Subaru Forester Is Unlocked

One of the easiest things to overlook is the vehicle's central locking system.

Depending on the model year and equipment, your Forester may prevent the boot from opening when the doors are locked.

Try the following:

1. Park the vehicle safely.
2. Press the unlock button on your key fob.
3. Unlock all doors.
4. Walk to the rear of the vehicle.
5. Press the boot release button near the number plate.
6. Check whether the tailgate opens.

If your Subaru has keyless entry, make sure the access key is nearby.

Some models allow tailgate access while the vehicle is locked, provided the appropriate access key is detected.

Our tip: If the boot opens after unlocking the doors, the problem may be related to the locking settings rather than the tailgate motor.

2. Check the Car Battery

A weak 12V battery is another possible reason your Subaru Forester boot won't open.

The powered tailgate depends on the vehicle's electrical system to operate its motor, electronic latch, and control components.

When battery voltage becomes too low, the system may behave unpredictably.

Signs of a weak battery

Look for these symptoms:

• The tailgate opens slowly or inconsistently.
• The boot release works intermittently.
• Interior lights appear dim.
• The engine struggles to start.
• Several electrical accessories malfunction.
• The power tailgate stops halfway through its movement.

How to check the battery

If you have a multimeter, check the resting voltage of the 12V battery.

As a general guide:

These figures are approximate and depend on battery chemistry, temperature, and recent charging.

If the battery is weak, have it charged and load-tested before replacing it.

For hybrid Forester models, follow the appropriate owner's manual instructions for accessing and servicing the 12V electrical system.

3. Reset the Subaru Forester Power Tailgate

If your Subaru Forester electric boot won't open, the power rear gate may need to be reinitialised.

This is particularly relevant when the tailgate has stopped during an opening or closing cycle, or when the system produces repeated warning beeps.

Subaru provides an initialization procedure for many Forester models equipped with a power rear gate.

How to reset the Subaru Forester power tailgate

For many 2019–2026 Forester models with the factory power rear gate, the procedure is:

1. Park on level ground and select Park.
2. Make sure the vehicle is stationary and the tailgate area is clear.
3. If the rear gate is completely closed, press and hold the exterior rear gate opener button for approximately five seconds until the latch releases.
4. Lift the rear gate carefully.
5. Lower the rear gate until the automatic closing mechanism takes over.
6. Allow it to close completely.
7. Try operating the power tailgate normally.

When the tailgate finishes closing, its initialization process should be complete.

What if the tailgate is already open?

If the power rear gate is stuck in an open position:

1. Make sure nobody is standing beneath the tailgate.
2. Carefully lower the gate until the powered closing operation begins.
3. Allow the gate to close completely.
4. Test the opening function again.

If it will not close completely, the applicable Subaru instructions may require holding the rear gate opener button for approximately five seconds before lowering it.

Important: Procedures vary by model year. Never force a motorised tailgate or attempt this procedure if the gate is binding, damaged, or unsupported. Follow your vehicle's owner's manual.

4. Subaru Forester Boot Not Opening and Beeping

Does your Forester boot beep three times but refuse to open?

This is an important clue.

On many Forester models, three short electronic chirps indicate that the power rear gate cannot complete the requested operation.

The system may have detected an abnormal condition requiring initialization.

Common reasons for the beeping

Possible explanations include:

• The power rear gate has stopped unexpectedly.
• An operating condition has not been satisfied.
• The system has detected an obstruction.
• The tailgate has encountered resistance.
• The gate requires reinitialisation.
• The battery voltage is insufficient.

How to fix it

Start by checking that:

1. The vehicle is completely stationary.
2. The transmission is in Park.
3. The doors are unlocked.
4. Nothing is obstructing the tailgate.
5. The 12V battery is in good condition.

Next, perform the applicable rear gate initialization procedure.

If the Forester continues beeping and the boot remains stuck, further diagnosis may be necessary.

A technician can inspect the power rear gate control system and identify stored fault information where supported by the vehicle's diagnostic equipment.

5. Check the Power Tailgate Button

Your Subaru Forester may have several ways to open the boot.

Depending on the trim and model year, these may include:

• A rear gate button on the dashboard.
• A button on the key fob.
• An exterior opener near the number plate.
• A hands-free tailgate feature.

If one method fails, try another.

For example, if the dashboard button operates the boot but the exterior button does not, the exterior switch or its wiring becomes a likely suspect.

However, if none of the opening controls respond, the issue may involve the battery, latch, power supply, or electronic control system.

Check the button operation

Some Subaru Forester models require you to press and hold the power tailgate button instead of tapping it briefly.

A quick press may not trigger the expected action.

Check the instructions for your model before assuming the button is faulty.

6. Inspect the Subaru Forester Boot Latch

A faulty boot latch is another common explanation for a rear gate that refuses to open.

The latch is responsible for keeping the tailgate securely closed.

If the mechanism becomes jammed, damaged, or electrically unresponsive, the boot may remain locked even when you press the release button.

Symptoms of a faulty latch

You might notice:

• A clicking sound without the boot opening.
• The rear gate sticking in the closed position.
• The boot opening only occasionally.
• Difficulty closing the tailgate.
• A boot-open warning when the gate appears closed.
• The latch failing to release despite normal button operation.

What can you do?

Start with a visual inspection when the latch is accessible.

Look for:

• Dirt and debris.
• Foreign objects.
• Corrosion.
• Loose or damaged components.
• Signs of misalignment.

If the latch is dirty, carefully clean the accessible area.

Use only a lubricant appropriate for the mechanism, and avoid saturating electrical switches or connectors.

If the latch actuator has failed internally, replacement may be necessary.

Do not use excessive force or insert your fingers into the latch mechanism.

7. Check for a Blown Fuse

If your Subaru Forester boot suddenly stopped opening, a blown fuse could be responsible.

Electrical circuits are protected by fuses designed to interrupt excessive current.

A blown fuse in a relevant circuit may prevent the power rear gate, latch actuator, or associated control equipment from operating.

How to inspect the fuses

1. Turn off the vehicle.
2. Locate the appropriate fuse box.
3. Consult your owner's manual for the relevant circuit.
4. Identify the fuse associated with the rear gate system, if separately protected.
5. Remove and inspect the fuse using a suitable fuse puller.
6. Replace a blown fuse only with one of the specified rating.

Fuse names and locations vary by model year and market.

Never substitute a higher-amperage fuse.

Subaru Forester Diesel Problems: Common Faults

If the replacement blows again, stop troubleshooting the circuit yourself and have the electrical fault diagnosed.

8. Check the Key Fob Battery

Sometimes, the boot problem is actually caused by the remote control.

A weak key fob battery can reduce the remote's operating range or prevent certain functions from working reliably.

Signs your key fob battery may be weak

• You need to stand closer to the vehicle.
• Remote locking works intermittently.
• The boot button rarely responds.
• The vehicle occasionally struggles to detect the key.

What should you do?

First, try the exterior boot button while the vehicle is unlocked.

If that works normally but the remote doesn't, check the key fob battery.

Replace the battery using the correct type specified for your key.

The required battery and replacement procedure can differ between Subaru Forester generations.

Remember that a key fob issue is less likely if the dashboard and exterior tailgate controls are also unresponsive.

9. Subaru Forester Boot Opens Halfway Then Stops

A Forester boot that opens partially before stopping may have a different problem from one that remains completely closed.

Possible causes include:

• An obstruction in the opening path.
• An activated tailgate height memory setting.
• A weak 12V battery.
• Excessive mechanical resistance.
• A failing powered support or motor.
• A sensor or control system fault.

Check the memory height setting

Many Subaru Forester models with powered tailgates have a memory function that allows drivers to limit the opening height.

This is useful in garages with low ceilings.

However, it can also make the boot appear faulty when it consistently stops at the same position.

On some earlier models, the system uses a physical memory switch.

On other models, the memory function can be managed through vehicle settings.

Check whether a low opening height has been saved.

If so, disable or reconfigure the memory function according to your owner's manual.

Check for resistance

Inspect the rear gate opening path for luggage, attached accessories, or other objects.

If the gate stops at different heights, makes grinding noises, or moves unevenly, it may have a mechanical or powered drive problem that needs professional attention.

10. Check the Tailgate Struts

The tailgate struts support the weight of the boot when it is open.

On models with manual tailgates, gas struts help lift the rear gate and keep it raised.

If these struts wear out, the boot may become unusually heavy or fail to remain open.

Signs of worn tailgate struts

Common symptoms include:

• The boot is difficult to lift.
• The tailgate drops after opening.
• The gate no longer stays fully raised.
• Movement becomes uneven.
• The struts show damage or leakage.

Worn struts are not normally responsible for an electronic latch refusing to unlock, but they can explain why the boot releases without lifting properly.

If your Forester uses powered rear gate supports, diagnosis and replacement should follow the appropriate service procedure.

Never work beneath a tailgate that cannot reliably support its own weight.

11. Inspect the Tailgate Wiring

Another potential cause is damaged wiring.

Electrical wires pass between the vehicle body and the rear gate to operate several components.

Depending on equipment, these may include:

• The tailgate release switch.
• Rear gate locking components.
• Rear wiper.
• Rear window heating.
• Number plate lights.
• Power tailgate equipment.

Repeated opening and closing can place stress on wiring near the tailgate hinges.

Over time, wires or connectors may become damaged.

How to recognise wiring problems

Electrical wiring becomes a stronger suspect when multiple rear gate features fail together.

For example, if the boot opener stops working at the same time as the rear wiper or number plate lights, there may be a shared wiring or electrical supply issue.

Inspect the flexible rubber wiring covers near the hinges for obvious external damage.

Avoid pulling apart the wiring harness unless you have the necessary electrical knowledge.

A qualified auto electrician can perform continuity and voltage tests to locate a broken wire or faulty connection.

12. Check the Power Tailgate Motor

If your Subaru Forester has a powered boot, the motorised opening system may be responsible.

The power rear gate uses electrically controlled components to move the tailgate.

These components can develop faults due to age, damage, electrical problems, or excessive resistance.

Signs of power tailgate failure

Symptoms may include:

• The boot unlocks but doesn't lift.
• The tailgate starts moving and immediately stops.
• One side appears to move unevenly.
• Unusual grinding or clicking noises occur.
• The power system works intermittently.
• The gate repeatedly stops despite successful initialization.

Can you repair the motor?

The answer depends on which component has failed.

Sometimes, a wiring repair or system initialization is enough.

In other cases, a powered drive unit, support assembly, sensor, or control module may require replacement.

Because these parts can be expensive, proper diagnosis is important before ordering a new component.

How to Open a Subaru Forester Boot Manually

If the boot is completely stuck, the Subaru Forester has an emergency rear gate release on many model years.

This allows you to open the tailgate from inside the cargo area when the normal release system doesn't work.

Subaru Forester emergency boot release

For many Forester models, the procedure is:

1. Park safely, switch off the vehicle and apply the parking brake.
2. Fold down the rear seats if necessary to gain access to the cargo area.
3. Locate the small access cover near the bottom centre of the interior tailgate trim.
4. Carefully remove the cover using a flat-head screwdriver protected with tape or a cloth.
5. Locate the emergency rear gate release lever behind the cover.
6. Follow the owner's manual illustration to operate the lever with the screwdriver. On many Forester models, the lever moves to the right.
7. Open the boot carefully.

Safety warning: Never use your fingers to operate the emergency release mechanism. Use the tool recommended in the vehicle's manual.

Some Australian-market Forester versions with double locking have an additional anti-theft cover that must be removed before accessing the lever.

The release layout can also vary between manual and powered tailgates.

Do not force the mechanism if the arrangement differs from your vehicle's manual.

Will the emergency release fix the problem?

The emergency release provides access to the boot, but it doesn't necessarily repair the underlying fault.

If the latch, wiring, or power tailgate system is defective, you should investigate the original problem before relying on the boot again.

Subaru Forester Boot Not Opening After Battery Replacement

Some drivers experience tailgate problems after replacing or disconnecting the vehicle's 12V battery.

This doesn't automatically mean the new battery is defective.

Possible explanations include:

• A loose battery connection.
• Low voltage in the replacement battery.
• An interrupted powered tailgate operation.
• An electronic control issue.
• A coincidental latch or wiring fault.

What should you check?

First, make sure the battery terminals are properly connected and that the battery has sufficient charge.

Next, unlock the vehicle and try the normal rear gate controls.

If the power rear gate has stopped unexpectedly, perform the initialization procedure specified for your model year.

Avoid repeatedly disconnecting the battery in an attempt to reset the tailgate. Battery disconnection is not a substitute for the manufacturer's initialization procedure and may affect other vehicle settings.

If the system still fails, professional diagnostics may be required.

Subaru Forester Boot Won't Open With the Key Fob

If your Forester boot won't open using the key fob, but opens normally with the exterior button, the remote control or its settings may be responsible.

Before buying a replacement key, try these checks.

Check the remote operating method

On many powered Forester models, the rear gate button must be held for the specified duration.

Some key fob settings can also be customised.

Subaru Forester Not Starting: Causes and Fixes

Make sure you're using the correct opening procedure.

Replace the key fob battery

If remote locking is also unreliable, replacing the key fob battery may help.

Try the spare key

If you have a second key, test its operation.

If one remote works and the other doesn't, the problem is likely related to the original remote.

If neither key works but the rear gate opens from the dashboard, check the vehicle's remote operation settings or have the system diagnosed.

Subaru Forester Boot Won't Open From Outside

What happens if the boot opens from the dashboard but not from the exterior release button?

This pattern can help narrow down the problem.

The powered tailgate motor and latch may still be functioning, but the outside release switch may not be sending the correct command.

Possible causes include:

• A failed exterior opener switch.
• Moisture entering the switch assembly.
• Damaged wiring.
• A loose electrical connector.
• Locking or access-key conditions that haven't been met.

First, unlock the vehicle and retry the outside button.

If the dashboard control consistently works while the exterior button does nothing, have the outside switch circuit inspected.

Replacing the entire power tailgate motor would generally be premature without testing the switch and wiring.

Subaru Forester Boot Problems by Model Year

Not every Forester uses the same tailgate equipment.

The correct troubleshooting steps depend on the generation, trim level, and market specification.

These are broad model-year groups rather than a list of established failure rates.

Subaru Forester 2013–2018 boot not opening

If you own an older Forester, pay particular attention to the boot latch, exterior release switch, and general condition of the vehicle's electrical system.

If equipped with an electric rear gate, check its memory switch and use the correct reset procedure for that generation.

Subaru Forester 2019–2024 boot not opening

For this generation, the power rear gate initialization procedure is a useful troubleshooting step when the system stops operating and sounds repeated electronic chirps.

Also inspect the 12V battery, opening conditions and exterior release switch.

Subaru Forester 2025–2026 boot not opening

Newer Forester models may include updated powered tailgate functions and settings, depending on the Australian variant.

If the power rear gate doesn't respond, check that the vehicle is stationary, in Park, and that the doors are unlocked.

Consult the current model's owner documentation before attempting an initialization procedure.

How Much Does It Cost to Fix a Subaru Forester Boot?

Repair costs vary depending on the problem, whether your vehicle has an electric tailgate, and the labour required.

For Australian owners, these are the main factors that influence the final repair bill.

These are relative cost categories rather than current workshop quotations.

For an accurate estimate in Australia, ask a Subaru service centre or qualified independent workshop for a quote using your vehicle's VIN.

If your Forester is still covered by a warranty, check your coverage before authorising paid repairs.

Can You Drive With a Subaru Forester Boot That Won't Open?

If the boot is stuck securely closed, the vehicle may remain driveable, provided there are no other mechanical or electrical safety problems.

However, the situation is different if the tailgate is partially open or cannot latch properly.

Driving with an unsecured rear gate can create several risks:

• Luggage may fall out.
• Exhaust gases may enter the cabin.
• The tailgate may move unexpectedly.
• Other drivers may be exposed to falling objects.
• The vehicle's body and latch components may be damaged.

Never drive with an unsecured tailgate.

If the boot cannot be closed and latched safely, arrange professional assistance before using the vehicle.

How to Prevent Subaru Forester Boot Problems

Although some electrical failures are difficult to predict, a few maintenance habits may help reduce the chances of future tailgate problems.

Keep the latch clean

Inspect the boot latch periodically for dirt and debris.

Avoid allowing loose luggage straps or other objects to interfere with the locking mechanism.

Maintain the 12V battery

A healthy battery supports reliable operation of the vehicle's electronic systems, including the power tailgate.

If your vehicle regularly struggles to start or shows electrical problems, have the battery tested.

Avoid forcing the power tailgate

Use the powered opening and closing controls as directed by Subaru.

Applying excessive manual force can damage powered tailgate components.

Check the tailgate supports

If the boot becomes difficult to lift or doesn't remain open, inspect the gas struts or powered support system.

Keep the opening path clear

Before using an electric tailgate, make sure there are no walls, garage doors, luggage, or other obstacles in its path.

Investigate repeated warning beeps

A warning beep should not automatically be ignored.

If the tailgate repeatedly stops, reverses, or refuses to open, investigate the cause before the problem becomes worse.

When Should You Visit a Subaru Mechanic?

Some Subaru Forester boot problems can be fixed with basic troubleshooting.

Others require specialist diagnostic equipment.

Consider booking a workshop inspection if:

• The power tailgate continues to fail after initialization.
• The latch won't release despite a healthy battery.
• The boot repeatedly produces warning beeps.
• The powered mechanism makes unusual noises.
• The tailgate moves unevenly or unexpectedly.
• Electrical faults affect multiple rear gate components.
• The boot cannot be securely closed.
• The emergency release mechanism doesn't operate as described in the manual.

A qualified technician can check the electrical power supply, switch inputs, wiring, latch operation and powered tailgate components.

This helps avoid replacing expensive parts unnecessarily.

Frequently Asked Questions

1. Why won't my Subaru Forester boot open?

Your Subaru Forester boot may not open because of a weak 12V battery, faulty latch, defective release button, blown fuse, damaged wiring, or power tailgate malfunction.

Start by unlocking the vehicle and trying the different boot opening controls. If the power rear gate makes repeated warning beeps, it may need initialization.

2. How do I reset my Subaru Forester power tailgate?

On many 2019–2026 Forester models, Subaru specifies holding the exterior rear gate opener button for approximately five seconds until the closed gate unlocks, lifting it, and then lowering it until automatic closing begins.

The system initializes when the tailgate closes completely.

Always confirm the procedure in your model-specific owner's manual.

3. Why is my Subaru Forester boot beeping three times?

Three short electronic chirps on many powered Forester tailgates indicate that the requested operation cannot be completed.

An abnormal operating condition, obstruction, or interrupted tailgate movement may be responsible.

Check the operating conditions and perform the appropriate initialization procedure if required.

4. Can I open my Subaru Forester boot manually?

Yes. Many Subaru Forester models include an emergency release mechanism behind a small access cover at the bottom centre of the interior tailgate trim.

The release is operated using a screwdriver or similar tool according to the owner's manual.

The exact arrangement depends on the vehicle's generation and equipment.

5. Why does my Subaru Forester boot open halfway and stop?

A Forester boot that stops halfway may have an activated height memory setting, an obstruction, low battery voltage, excessive mechanical resistance, or a problem with the powered opening system.

If it consistently stops at exactly the same height, check the memory setting first. If it stops unpredictably or makes unusual noises, professional diagnosis is advisable.

Conclusion

If your Subaru Forester boot is not opening, there's a good chance the problem can be narrowed down with a few simple checks.

We recommend starting with the central locking system, key fob, battery condition, and exterior release button.

For Forester models with an electric tailgate, checking the operating conditions and performing the correct power rear gate initialization procedure may restore normal operation.

However, if the boot remains stuck, makes unusual noises, or refuses to latch securely, the problem may involve the latch assembly, wiring, or powered tailgate mechanism.
