Why is water leaking into the car trunk?
2 Answers
Water leakage may be caused by poor sealing of the trunk's rubber seal, faulty tail light seals, improperly closed sunroof, or clogged drainage pipes. The maintenance methods and functions of the trunk are as follows: Trunk maintenance methods: Use a brush to clean dirt during washing, including the edges and grooves of the trunk. Lay a trunk mat to prevent dirt or liquids from entering and corroding the trunk surface, while also preventing items in the trunk from sliding and reducing the risk of contamination or damage. Functions of the trunk: It serves as the car's storage compartment, enhancing convenience in daily life. The trunk contains a spare tire, vehicle emergency kit, onboard tool kit, warning triangle, fire extinguisher, and the emergency fuel tank release cable.
I recently helped a friend troubleshoot a trunk water leakage issue, and found it's actually quite common. First, check the rubber sealing strip around the trunk lid - when it ages and cracks, rainwater can seep through. Then inspect the drainage holes at the bottom of the trunk; if they're clogged with mud or leaves, water backup can cause serious problems. Also, pay attention to the wiring harness grommets - if the sealant comes off, or if the metal panels weren't properly repaired after a collision, these can become leakage paths. The most overlooked spot is the tail light gaskets - I've seen many cars get water ingress due to aged lamp sockets. My advice: after rain, immediately check the spare tire well. If you find standing water, clear the drains or replace seals promptly, otherwise water damage to wiring will cost much more to repair.
