What are the reasons for the trunk not closing?

[Reagan]

The reasons for the trunk not closing are: 1. Use of excessively stiff spring rods; 2. Poor matching between the closing limit rubber block and the locking mechanism; 3. Malfunction in the trunk control circuit; 4. Failure of the trunk hydraulic support rod; 5. Displacement of the trunk switch; 6. Lack of lubrication in the lock block; 7. Foreign objects obstructing the trunk slot. The solutions for a trunk that won't close are: 1. Lubricate and adjust the trunk; 2. Clean the trunk slot; 3. Replace the spring rod with one of moderate stiffness; 4. Check the trunk control circuit for faults; 5. Replace the trunk hydraulic support rod; 6. Adjust the position of the trunk switch.

I've driven quite a few cars before and encountered the issue of the trunk not closing properly several times. The most common cause is a damaged latch, such as rust preventing smooth engagement or a broken internal spring. Additionally, if the hinges of the trunk are rusted, loose, or deformed, the entire lid may become misaligned and fail to close tightly. Sometimes, overloading the trunk with too many items can obstruct the latch mechanism, preventing proper closure. For models with power liftgates, button malfunctions or control module failures can also trigger such issues. I once parked under a tree, and leaves accumulated in the gaps, causing the latch to fail. Safety-wise, driving with an unsecured trunk is hazardous—it may open automatically on bumpy roads and allow dust or water ingress. For inspection, first empty the trunk and try manually pressing it shut gently. If that doesn't work, promptly visit a professional repair shop to prevent minor issues from escalating into major repairs.

I've been through this before. Just after moving some stuff, the trunk got stuck and wouldn't close. Turned out a luggage bag was jammed near the lock. There are actually quite a few reasons: aging or deformed locks are most common; minor collisions causing tailgate deformation; rust in the hinge area making movement less smooth. For newer cars, issues with the electric tailgate control button are also frequent. My friend's car had this happen because the key battery died, interrupting the signal. It's not hard to deal with - first remove any obstacles, then gently push a few times to see if it catches. When loading items, don't overfill - leave some space for easier closing. Driving with an unsecured trunk is noisy and dangerous, so it's best to fix it promptly.

There are only a few main reasons why the trunk won't close: the lock is broken or rusted stuck; the hinges are deformed or corroded; too many items are blocking it. When this happens, try manually pushing it tighter to see if it locks. Safety first—don't drive fast if the issue isn't resolved to prevent the trunk from suddenly opening on the road. Regularly lubricate the hinges and lock to prevent problems.
