Therefore, the luggage falling from the vehicle’s trunk can be extremely dangerous for the other vehicles moving on the road as they can meet an accident. Thus it becomes essential to solve the problem of the faulty trunk door on a vehicle.

  • Mostly, the trunk on the BMW X3 might open due to the accidental press of the key fob button.
  • The accidental press of the key fob button happens when the fob is in the pocket, and the person takes support from something, which causes the fob button to press.

  • Select a pouch that is highly durable, waterproof and perfectly fits the BMW key in it.
  • Once you have found a pouch, place a small card of minimum thickness inside it. Keep the pouch in your pocket once the car is placed in the pouch but the key behind the car.
  • Putting a card in the pouch creates a hard surface, which prevents the button from accidentally getting pressed. Therefore the chances of the trunk opening automatically will be reduced.

Troubleshooting the trunk door opening automatically due to a faulty latch anchor.

  • The trunk on a BMW X3 uses a latch and striker mechanism. The striker is present on the tailgate while the latch is attached to the vehicle’s surface.
  • The striker present on the tailgate can get bent or misaligned due to physical damage caused on the tailgate, such as a dent.
  • The physical damage to the vehicle’s tailgate can cause the striker to bend, surely misalign it from getting properly locked in the latch. Thus due to this reason, there are chances that the trunk might open automatically.
  • Therefore to solve this problem, you will need some basic tools such as a screwdriver which can be used to apply force and bring the striker back to its original position.
  • Open the trunk of the vehicle and figure out the striker’s position. If the striker isn’t at a 90-degree angle, then the striker is misaligned from its location.
  • To bring the striker back to its original location, you need to pass the screwdriver from the slot present in it. Once the screwdriver is passed through the slot, apply a force on the screwdriver to move the striker towards becoming straight.
  • Once the striker gets back into its original position, remove the screwdriver and check whether the trunk closes properly. 
  • If the trunk closes properly, the striker is back in the correct position, and the trunk opening is automatically solved because the latch can now grab the striker properly.
