What Causes Water Leakage in the Buick Excelle Trunk?
3 Answers
Reasons for trunk water leakage: 1. Sealing strip: The waterproofing of various parts of the car body is ensured by sealing strips, which are made of rubber material. These strips possess certain strength and hardness, preventing deformation under specific pressure conditions. 2. Trunk deformation: The design of the car trunk follows specific rules, with corresponding drainage curvature designs in areas A, B, C, and D. Below are additional details: Solutions: It is essential to clean the sealing rings multiple times during spring and autumn, using damp cotton for gentle wiping. If the car is to be stored for an extended period, ensure a thorough cleaning before storage to prevent natural aging during parking. Talcum powder is generally chosen for cleaning purposes.
When I drove a Buick Excelle before, I also encountered the issue of water leakage in the trunk, which was quite annoying. The main causes were aging or damaged sealing strips, allowing rainwater to seep through gaps, especially for cars frequently parked outdoors exposed to wind and sun—hardened and cracked rubber seals are a common problem. Additionally, clogged drainage holes can be an issue; the drainage holes near the trunk lid edges or chassis can easily get blocked by leaves or mud, causing water to backflow. I remember once after washing the car, I forgot to clean it, and during heavy rain, water leaked in. Another common cause is rust or small holes in the car body, particularly in older vehicles or areas damaged in accidents that weren’t properly repaired. I recommend regularly checking the condition of the sealing strips and replacing them immediately if cracks are found, as well as cleaning the drainage holes periodically. A simple test is to lay a white sheet of paper inside the trunk, spray water on the exterior with a hose, and observe where the leakage occurs. Don’t wait until mold forms or items get damaged before taking action.
Having driven a Buick Excelle for several years, the experience of water leakage in the trunk has taught me a lesson. The most common issue is with the sealing strips—the original factory material isn't durable and can deform easily under wind and rain, allowing water to seep in. Clogged drainage holes are another major cause; these are typically located under the rear lid or near the wheel arches, and when blocked by dust or debris, water can't drain and flows back in. Additionally, if the sunroof drainage pipes extend into the trunk area, cracks or detachment can lead to water infiltration. When inspecting, start by checking the sealing strips for cracks and feel if they're still flexible. To clear drainage holes, use a thin rod or compressed air to blow them out. I usually avoid parking under trees to prevent debris buildup and clean the drainage holes during car washes. Fixing these issues early saves both hassle and money.
