Tesla Trunk Button Not Working (7 Reasons Why)

Imagine you went grocery shopping on a Sunday evening and placed your purchases in the trunk of your Tesla car.

When you go home and press the trunk button to let groceries out, you discover that the trunk button has stopped working and the trunk on your Tesla is still closed.

You must be worried because the trunk is full of perishable items. Isn’t this situation frustrating you? Yes, of course.

We experienced a similar problem and conducted extensive research to identify the causes and potential remedies for the Tesla Trunk button not working.

In this article, I’ll thoroughly describe the causes of the Tesla Trunk button not working, along with all possible solutions. So, let’s get started.

Location of Tesla Trunk Button and its Function

Locations

liftgate: You can open the trunk with the button located under the liftgate’s exterior handle.

Key Fobs: The majority of Tesla key fobs include a specific button that either has the word “Trunk” printed on it or has a shape like an image of a trunk.

Car Interior: On the touchscreen, there are typically physical buttons. There might be a trunk-like icon on the touchscreen or on the buttons that you can press to open the trunk.

Tesla App: You can remotely open and close the trunk from your smartphone if you have the Tesla mobile app.

Function

Your Tesla vehicle’s trunk or rear space can be opened and closed electronically with the trunk button.

The electronic system of the car receives a signal when the trunk button is pressed, releasing the latch on the trunk or opening it.

This signal can also be received inside the car. This enables you to reach the trunk storage area of the vehicle without actually requiring a key to unlock it.

Reasons and their possible solutions for the Tesla Trunk button not working

There are many reasons for the Tesla trunk button not working. These causes include software glitches, issues with the remote control, faulty key fob, physical obstructions, and defective trunk equator issues.

1. Software Glitches

Sometimes, a minor software glitch can cause the trunk button to become unresponsive.

Solutions

There are the following solutions you can try to troubleshoot and fix the problem if you run into a software bug that prevents the Tesla trunk button from functioning.

1. Restarting your car’s infotainment system might help. To accomplish this, you should follow these steps

  • Select “Controls” from the touchscreen
  • Select “Safety & Security,”
  • Now you have to select “Power Off.”

Before starting the car again, wait a moment. Then restart again to reboot the system.

2. You should try performing a soft reset on the dashboard touchscreen of the car if the trunk button is still not functioning.

For this, you have to hold down the two scroll wheels to the left and right of the steering wheel until the screen turns black and the Tesla logo displays to complete the procedure.

3. You should make sure that the software on your Tesla is updated. Tesla often provides software updates that can fix software-related errors and issues.

Check for updates in the settings menu of your car and download them after connecting it to a Wi-Fi network.

Follow these steps to do so:

  • First of all, you should ensure that your Tesla vehicle is connected to a stable network connection.
  • On the touchscreen display of your Tesla vehicle, go to “Controls”.
  • There you will see an option for “Software”. Tap on it.
  • When you enter the software option, you will see any “Software update” if available.
  • If there is any pending Software update, you should click on the “Download and Install button”.

2. Issues with Remote control signals

The issue may be with the signal transmission if you’re attempting to open the trunk using the key fob or the Tesla mobile app.

Solutions

There are the following solutions for the problem of signal transmission from remote control.

Position yourself such that you can see the car well and are within a reasonable distance of it. You should try once more to open the trunk while standing closer to the car.

Your key fob’s signals may be affected by interference from other electronic devices or radio frequencies. To solve the problem, you should try using the key fob in several locations.

3. Faulty Key Fob

Tesla key fobs are small wireless devices that give owners remote access to some features of their cars.

They provide convenient access to the vehicle’s capabilities and act as a physical key alternative to the Tesla smartphone app.

If the key fob is defective, it can affect the functionality of the Tesla trunk button.

Solutions

There are the following solutions if your Tesla trunk button is causing problem due to a faulty key fob.

You should make sure that the key fob’s battery is in good condition. It may be difficult to transmit signals with a weak or empty battery.

Replace the battery of the key fob of your Tesla with a new one if necessary.

The key fob’s connection to the vehicle’s security system may occasionally become weak.

Follow these steps to re-sync the key fob:

  • Go inside the car with your Tesla key fob and lock all the doors and windows.
  • You have to press the brake pedal while seated in the driver’s seat.
  • Hold your key fob before the center console or steering wheel.
  • For around 10 seconds, simultaneously press and hold your key fob’s lock and unlock buttons.
  • Release the buttons, then verify that the key fob is now functioning properly.
  • If you have more than one key fob for your Tesla, try using a different one to determine if the problem is solely related to the key fob.

4. Physical Obstructions

The trunk may not be opening properly due to an obstacle, such as luggage, goods, or even a twisted trunk latch.

Solutions

There are the following solutions for this problem,

1. You should open the Tesla’s back doors and take a close look at the trunk. Look around for any bulky objects, baggage, or other items that might be in the way of the trunk.

2. You should also look within the trunk’s sidewalls for anything that can inhibit a full opening.

3. You should carefully remove any items that are obstructing the trunk. While removing the barrier, take care not to harm any delicate or electronic components.

4. The trunk latch could occasionally become misplaced or stuck, making it difficult to open. You should gently check the latch to make sure it operates smoothly and is not stuck.

5. Defective Trunk Actuator

The mechanical opening and closing of the trunk are controlled by the trunk actuator. The trunk button might not function if the Trunk actuator is defective.

Solutions

There are the following solutions to resolve the problem of defective trunk actuators:

You’ll probably need to replace the actuator if the malfunctioning trunk actuator is the cause of the problem with button.

For this, you should follow these steps,

  • Put your vehicle on “Park” by applying parking brakes.
  • You should have a replacement actuator that is compatible with the Tesla model.
  • You should have the necessary tools for replacing the trunk actuator such as screwdrivers, wrenches, and pliers
  • Typically, the trunk actuator is found inside the trunk lid of your Tesla. It is a component of the trunk latch system, which locks and unlocks the trunk.
  • You should disconnect the electrical and mechanical connections with the trunk actuator and carefully observe the position of the actuator, as it will help in the placement of a new one.
  • Carefully remove the faulty trunk actuator from its position and set the new one by tightening the bolts.
  • Now, you should reconnect all the electrical and mechanical connections with the new trunk actuator as they were attached to the old one.
  • Now, check the trunk button to find out that the new trunk actuator is working properly and the trunk button issue has been resolved

6. Power issues

A blown fuse or an electrical issue could be the cause of the trunk not getting power.

Solutions

There are the following solutions to solve power-related problems.

For any blown fuses connected to the cargo space or trunk, check the fuse box. If a fuse blows, replace it with the right one.

In a Tesla, the fuse box is typically found under the glove compartment, near the battery, in the front trunk.

The diagram showing the fuse’s position and purpose is located on the fuse box cover or in the owner’s handbook. The fuse number 30A is specific for the rear trunk

To replace a fuse with a new one, you should follow these steps:

  • You should disconnect the negative terminal of the 12-volt battery before working on any electrical components to prevent any electrical risks.
  • Find the fuse for the trunk once the battery has been unplugged. To see if the fuse is blown, visually inspect it. There will be a fractured or melted metal strip inside of a blown fuse.
  • Replace any blown fuses with new ones with the same amperage rating. To protect the electrical system in your car, only use the Tesla-specified fuse type.
  • Reconnect the negative connection of the 12-volt battery after replacing the fuse.

7. Contact Tesla Service Center

The best course of action is to get in touch with Tesla customer care or book an appointment at a Tesla service center if you have attempted all of the above solutions and the trunk button is still not functioning.

Certified specialists will be able to precisely assess the issue and carry out the required fixes to get your trunk button working once more.
