Why is the trunk of the Buick Excelle leaking water?
2 Answers
Most of the reasons for water leakage in the trunk of the Buick Excelle may be due to the installation of a reversing camera, which damages the vehicle's sealing and causes water to enter the compartment. Below is relevant information about the car trunk: Maintenance: Keep the vehicle trunk clean and tidy, and use the mesh pockets on both sides correctly. Most cars are equipped with these pockets to store items that are prone to rolling, such as flashlights and small fire extinguishers. They do not take up much space, but it is not recommended to pile them together, as the items may fall out of the mesh pockets due to bumps during driving. Precautions: Flammable and explosive items are prohibited. The interior of a car is a relatively enclosed space, and after being exposed to the sun in summer, the internal temperature can become very high. Storing flammable and explosive items in the trunk may lead to spontaneous combustion or explosion due to the high temperature.
My Buick Excelle also had the embarrassing issue of 'raising fish' in the trunk last year, with accumulated water under the floor panel. There are generally three common scenarios: 1) The sealing strip around the trunk edge ages and cracks, allowing rainwater to seep through gaps; 2) The sealing gasket of the rear taillight deforms, letting high-pressure car wash water directly enter; 3) The drainage holes on both sides of the undercarriage get clogged with dead leaves and mud, causing rainwater to backflow into the trunk. Pay special attention to the area around the rearview camera—poor sealing of wiring holes there makes it particularly prone to leakage. Also, another possibility is broken sealant at the rear panel's sheet metal joints (often originally sealed with silicone). If impacted, the sealant may fracture and require reapplication, otherwise leaks will worsen progressively.
