What is the reason why the trunk suddenly cannot be closed?

[DeMolly]

The main reason the trunk cannot be closed is due to a lack of lubrication inside the trunk door lock, causing parts to jam and preventing it from functioning properly, thus making the trunk unable to lock. Below is an introduction to the electric trunk: 1. Overview of the electric trunk: The trunk can be opened or closed electrically or via remote control. To open the trunk, simply press the button inside the car or on the remote key, and the trunk will open automatically. To close the trunk, press the close button inside the trunk, the close button inside the car, or the remote key, and the trunk will close automatically. 2. Structure of the electric trunk: The basic structure consists of two core shaft drive rods.

I've been driving for ten years and have encountered the issue of the trunk suddenly not closing several times, with various causes. The most common is dust or small stones stuck in the latch, causing a clicking sound when closing but failing to lock. If the hydraulic support struts are broken, the lid may sag, affecting closure, especially noticeable on rainy days. For electric trunks, it could be loose wiring connections, a blown fuse, or sensors falsely detecting obstacles and preventing closure. Last time I had this issue, a simple fix was cleaning the latch and applying lubrication; if that didn't work, disconnecting the power to reset the system might help. Don't force the trunk closed as it can scratch the paint or injure your hands. Driving with the trunk open on the highway leads to loud noise and dust ingress, so get it repaired promptly to avoid safety risks. Regular maintenance checks on the struts and latch can prevent many such troubles.

The trunk suddenly getting stuck and unable to close is, in my opinion, mostly caused by mechanical failures. Rusted or worn-out latches can prevent the door from sealing properly, or broken internal springs may fail to return to their original position. Additionally, aging hydraulic or pneumatic struts losing their support can cause the door to tilt and fail to close. Issues with the electrical system are more complex, such as short circuits stopping the motor or dirty sensors misjudging positions. The first step is to manually check if the door is balanced and aligned; if you have tools, inspect the wiring connections and fuses. Don’t delay repairs—an open trunk increases wind resistance, wastes fuel, and poses a risk of items falling out. From my experience, simple lubrication can solve half the problems; for complex electrical faults, it’s safer and more convenient to visit a professional shop. During maintenance, pay attention to cleaning the locks and struts to prevent such sudden issues.

As an older person, I've seen plenty of trunk issues. Sudden failure to close is often due to simple reasons. Dust accumulation or debris blocking the latch, or failing support rods causing the door to sag too low to shut properly. Nowadays, new cars come with electronic components, and sensor false alarms detecting obstacles are also common. The solutions are quite straightforward: manually shake the door to check for looseness, clean any debris from the latch points, apply some lubricant and try closing it again. If that doesn't work, it might be a wiring or fuse issue requiring replacement. A trunk that doesn't close properly isn't just unsightly; wind and rain can bring dirt inside the car, affecting health. Early detection and action can save you from expensive repairs later.
