Why Is Your Tesla Trunk Not Opening? (Fixes added)
A Tesla trunk may not open for a variety of reasons, each of which may have a unique fix. Here are a few frequent causes and additional fixes:
1. Software Glitches:
The most frequent cause of a trunk not opening is a recent software update; Trunk opening problems might easily result from an unsuccessful software update.
Fix:
Tesla often identifies problematic software quickly, and the issue typically disappears with a successful update. As updates vary according to VIN, it may take some time for this to reach all owners.
So, to update the software right after an unsuccessful, reset the car and install the software.
- Press two of the scroll buttons on the steering wheel for ten seconds. You can then turn off the engine of the vehicle and wait two minutes before using the brakes.
- Go to Controls > Software > Update Available > Software Update on the dashboard of the vehicle. Let it finish downloading after that.
- Click Software Update > Install or Yes in the Tesla App on your phone.
2. Trunk Latch Obstruction:
A latch is responsible to secure and unlock its trunk from operating properly. Sometimes, the latch gets stuck with objects or debris. So, when the latch can’t work as it should because of the obstruction, the trunk may not be able to open.
Fix:
Examine the area for any debris or objects that may be preventing the latch mechanism. Consider getting rid of any obstacles you find.
In some instances, rust or a lack of lubrication can make it difficult for the latch to operate well. To make sure the latch mechanism moves easily, lubricate it with an appropriate automotive lubricant.
3. Damaged Cinch Motor
The defective clutch motor or actuator in the tailgate is typically to blame for the Tesla’s trunk problem.
Fix:
In this case, you might need to change the Clinch Motor. To change this part, you must enter the rear trunk through the back seats.
Simply fold the backs of the seats in the third row, and then enter the trunk of the vehicle from the back. Then:
- Remove the right trunk cover from the back. For the removal of the fabric covering, loosen the Torx screw located beneath the plastic using a T20 or T25 Torx screwdriver.
- Disconnect the black plug from the power liftgate module to open the lift gate.
- Remove the plastic trim on the bridge, the side vertical trims, the headliner side bolsters, and the parcel shelf supports.
- Disconnect the lift gate’s top plastic trim from the back. However, due to its connection to the handle inserts below the liftgate, you cannot completely remove this part.
- Take off the thick plastic covering.
- You can find a button by taking these components off. Press the button with a paperclip, and then remove the speaker plug.
- You will find the troublesome clinch motor that sits above the liftgate opening region, behind the plastic trim.
- After releasing the Bowden cable from the clinch motor’s puller arm, remove the screws.
- Install the new Cinch Motor and check the lift gates if they are working well or not. Then, install the parts again that you had removed to insert the motor.
4. Broken Wiring Harness of Trunk
Your Tesla’s trunk may not be opening because of a damaged wiring harness.
Fix:
In this situation, you need to change the harness and for that, you should seek the professional’s assistance.
It is recommended to have a qualified expert complete this service because it includes electrical operations and trying to do it yourself would be risky.
5. Faulty Key Fob and Mobile app issues
Users of Tesla vehicles unlock the trunk and control the vehicle with a key fob or smartphone app.
However, a broken key fob or a problem with a mobile app can make it difficult to access the trunk.
Fix:
Make sure the key fob’s battery isn’t dead if you’re using one to open the trunk. Lack of responsiveness may be a sign of a weak or dead battery. So, change the battery.
- Re-synching the Key Fob is an option. Consult your owner’s manual or the Tesla website for the manufacturer’s instructions on how to re-sync the key fob with your Tesla. Check the network connection on your smartphone if you’re using the mobile app; it needs to be strong.
- Reinstall the mobile app if the first installation was unsuccessful. This can fix conflicts or software bugs that are the root of app-related problems.
- You can update the Tesla app to have better operation. You can also log out and log in again on the mobile app. It will solve the communication gap between the app and your Tesla.
