What Causes Water Leakage in the Envision's Trunk?
3 Answers
Generally, there are two scenarios that can lead to water leakage in the trunk. The first is a leak in the trunk's sealing strip. To identify this, you can perform a spray test, but it requires someone to spray water from outside the trunk while another person checks inside. The second, less common scenario involves water being splashed into the trunk due to damage to the negative pressure port caused by the tires. This is relatively rare, and a thorough inspection is recommended. Below is some relevant information: Buick Envision: The Chinese name for the Buick ENVISION is "Ang Kewei." As a new-generation strategic model under General Motors, the Buick Envision's exterior design inherits the essence of the ENVISION Vision concept car. Model Design: In terms of appearance, the 2020 Buick Envision showcases a more robust and bold aesthetic. The new wing-shaped chrome trim runs through the LED wing-shaped headlights, enhancing the vehicle's horizontal visual width. The dynamic front bumper design and three-dimensional silver lower guard create a full and powerful front fascia. The rear also features a three-dimensional wing-shaped design, with chrome trim connecting the taillights, complemented by integrated dual exhaust pipes to accentuate the sporty feel.
I also experienced water leakage in the trunk when driving my Envision, which was really frustrating! The main cause is usually the aging of the rear windshield sealing strip, which starts to loosen and leak after a few years of use, leaving a wet patch during heavy rain. Clogged drainage holes due to mud or fallen leaves are also troublesome, as neglecting regular cleaning can cause water to back up. Poorly sealed body seams or substandard sheet metal repairs can lead to water seepage, especially in some refurbished used cars that weren't handled properly. If the sunroof's drainage tube gets blocked, the water flowing down can also enter the trunk. I suggest you open the trunk and check if the surrounding seals are damaged; then try clearing the drainage holes with a small stick. If the problem persists, take it to a professional repair shop for inspection to prevent water damage to stored items. Parking away from trees to reduce debris accumulation is a good long-term preventive measure.
As an Envision owner, I've found that water leakage in the trunk is mostly caused by sealing issues. Cracks or deformation in the rear hatch rubber seal allow rain and snow to seep in, especially during humid seasons. Clogged drainage holes at the bottom of the body are another factor - when blocked by dirt, water accumulates and flows into the spare tire well. Additionally, poor sealing at body joints like welding seams can cause leaks through gaps. For maintenance, I recommend first wiping the trunk edges with a soft cloth to check for leaks; clear any debris from drainage holes to ensure proper flow. If there's significant water ingress, it might also relate to the rear wiper mounting holes. Early treatment prevents corrosion of wiring harnesses and odors. Regularly lubricating seals during maintenance extends their lifespan. If DIY fixes don't work, driving to a 4S shop for minor repairs is a cost-effective solution.
