Why Subaru Outback Trunk Won’t Open: Behind the Reasons & Solutions

As it is quite a common problem, you might have already experienced a faulty Subaru Outback trunk. If your Subaru Outback trunk won’t open, there can be various reasons behind this glitch.

Having a defective trunk is always a problem when your hands are full of groceries or stuff that you have to dump into the trunk.

Sometimes this problem in your trunk can be caused due to severe reasons like a dead battery, a broken latch or key, or a non-responsive Subaru key fob.

If you want to open your trunk again, you will first determine the underlying issue and then resolve the problem.

5 Reasons Why Subaru Outback Trunk Won’t Open

As mentioned earlier, if your Subaru Outback trunk is not working, it can be for various reasons.

For your convenience, we will discuss all the problems below leading to a faulty trunk of your vehicle.

So, before wasting any more time, let’s dig into issues you might face if your car’s trunk is giving you trouble.

01. Dead Battery

Having a dead battery is one of the most severe problems that can lead to various failures in your vehicle, along with a faulty trunk.

In case that you are trying to open your Subaru’s trunk or any of the doors automatically, a chance is that you have a dead battery.

If you want to check whether this is the problem or not, you can unlock your car manually through the driver’s door and insert the key into the ignition.

Now, turn your key around into the very first position. If your radio, lights, and other elements are not turned on with the turning of the key, it is a sign that your vehicle’s battery is dead.

In this case, you should fix the car’s battery immediately.

For some Subaru Outback models like the 2013 or newer ones, you will not unlock the trunk because they do not support manual unlocking.

Whatever the case is, you will have to fix the battery to move your car.

02. Trunk Lock or Latch is Broken

If your vehicle’s battery is not a problem and you hear a clicking sound while unlocking your trunk but it doesn’t open, your car might have a broken lock or latch.

Although this is not a very common problem in Subaru Outback, you still might face it as it can happen due to specific reasons.

For example, if you open and close the trunk of your vehicle quite frequently or drive through rough terrains, you might face this problem.

Also, if the release button is not working correctly or you hear a non-stop clicking sound while opening the trunk of your Subaru Outback.

These are all the symptoms of a broken trunk latch or lock.

03. Key FOB is not responding.

Suppose you are using a key FOB to open your car, and it won’t open while your vehicle starts completely fine.

In that case, there might be a problem with your key FOB.

If your key FOB is not working, it can be due to various reasons, including that the battery of the key FOB might be dead, any internal wiring issue in the key, or car, or the key needs a reset.

04. Trunk Cable is Damaged

Some vehicles do not have any handle on their trunk and are opened through a lever located in the cabin.

In this case, when there is no handle, a trigger button is located near the driver’s seat responsible for opening up the trunk.

This trigger button and the trunk latch are connected through a cable that opens up the trunk.

So, if your vehicle’s trunk is not opening up, there is a chance that this cable might be damaged or broken.

5. Faulty Lock Actuator

Among the other problems and reasons, the lock actuator might also be causing any problems if your vehicle’s trunk is not opening.

Lock actuator is responsible for controlling the lock present on your trunk. This part is a small motor with gears that shift as you try to open your car’s trunk.

If this motor is faulty or dead, your Subaru Outback’s trunk won’t open up as the trunk latch would not be working to open or close the trunk.

Solutions for the Subaru Trunk Problems

Now that we have discussed various problems that might lead to a faulty trunk of your vehicle, it is time to discuss their solutions. Below are the solutions to the issues discussed above;

  • Recharge the battery

  • Repair or install a new lock and latch system

In case that the problem causing a faulty trunk in your vehicle is a damaged or broken lock or latch system, you will have to fix it or replace it with a new one.

  • Get the Key FOB fixed.

Once you have determined that key FOB is the problem, you can get it fixed.

As mentioned earlier, you will have to check what is causing the pain, whether the battery, the wiring, or it needs to be reset. Now, fix the problem accordingly.

Now that the cable connecting your trunk latch and trigger is damaged, you will have to repair it or replace it with a new one if required.
