Why is the sunroof of GAC Trumpchi leaking?
2 Answers
Mostly, the sunroof leakage in cars is caused by blocked drainage pipes, while door leakage is generally due to aging window seals or clogged door drainage holes. Door leakage can result in water seeping out from the door panels and, in severe cases, lead to water accumulation under the cabin carpet. Poor rainwater drainage: Blocked sunroof drainage outlets can cause poor rainwater flow, gradually seeping into the car. This phenomenon mainly occurs when the owner neglects regular cleaning of the roof, allowing debris to flow with rainwater and clog the drainage outlets. Damaged sunroof seal: The sunroof seal is made of rubber and can age over time. Repeated friction from the sunroof glass can cause damage, leading to poor sealing and leakage during rain. In such cases, it's essential to regularly check the condition of the seal and replace it promptly if damaged. Roof deformation: If the car suffers an impact, the body may deform. Improper restoration during repairs can result in poor sealing and subsequent leakage.
Every time I drive my GAC Trumpchi, I pay special attention to the sunroof issue. The main cause of leakage is often clogged drainage holes, especially when parked under trees with lots of fallen leaves. Aging or deformed seals are also common, as plastic tends to crack over time. Prevention is key: I recommend checking the drainage holes every quarter and gently clearing them with a thin wire; applying some silicone grease to the seals can prevent drying and cracking. If leakage occurs, address it immediately, as wet carpets inside the car can lead to mold or corrode wiring, causing bigger problems. Also, avoid using high-pressure water jets on the sunroof during car washing, as the high pressure can easily damage the seals. Regular maintenance can extend the sunroof's lifespan by several years, saving both hassle and money.
