Why is there water in the Buick Excelle trunk?

[VonCamila]

Water leakage in the car trunk is caused by poor sealing of the weatherstrip or damage and deformation of the trunk. Below are the relevant details: 1. Dimensions: The Buick Excelle is a compact 4-door 5-seater sedan with a body length of 4609mm, width of 1798mm, height of 1486mm, and a wheelbase of 2640mm. 2. Powertrain: The Buick Excelle is equipped with a 1.3T turbocharged engine and a 6-speed automatic transmission, delivering a maximum power of 120 kW and a maximum torque of 230 Nm. It features front-wheel drive, with a front suspension using MacPherson strut and a rear suspension using multi-link independent suspension.

I once encountered a water leakage issue in the trunk of my Buick Excelle. After rainy days, the trunk was always damp, which was really annoying. Upon careful inspection, I found that the sealing rubber strip had aged and, over time, deformed and cracked, allowing rainwater to seep in through the gaps. Additionally, the sealing ring around the taillight assembly is prone to damage, and water can quietly leak in through the light socket. Moreover, the drainage holes at the bottom of the trunk were clogged with mud and leaves, preventing water from draining and causing it to backflow into the cabin. If the body welding points rust or are not repaired properly, larger gaps can also let rainwater seep in. After driving for so long, these minor issues are quite common. I recommend going to a professional shop as soon as possible to check and replace the seals and clean the drainage holes, otherwise, items in the trunk could get soaked and ruined, which would be a real headache.

In daily car maintenance, there are various reasons for water leakage in the trunk. The most common cause is the failure of sealing strips, which harden and crack over time, allowing water to seep into the cabin during rainy days. For the Buick Excelle, aging or improperly applied sealant around the rear taillight installation area can lead to water penetration. Blocked drainage channels and holes, such as clogged drainage grooves along the trunk edges due to debris, can cause water to overflow into the cabin. Poor sealing at body panel joints, especially near the rear bumper, is also a frequent issue, posing greater risks during car washes or rainy weather. I recommend first using a towel to clean up any accumulated water, then checking if the drainage holes are clear, and promptly replacing damaged seals to prevent moisture damage to electronic components.

Water entering the trunk is usually caused by failed waterproofing measures. Worn or deformed sealing strips allow water to seep through gaps. Damaged tail light gaskets let rainwater leak in through the lamp sockets. Blocked drainage holes causing water backflow is also common. Poorly sealed body seams, such as welding joint issues, can lead to leaks. It's recommended to inspect and clean promptly to prevent rust.
