The car leaks due to a leaky sunroof, causes and solutions

The sunroof is not simply a convenient equipment, but also a factor that helps increase the luxury of your car. However, sometimes this luxurious equipment puts users in a “crying bad” situation because of leaks. So where does a leaky car sunroof come from and how to handle it?

What causes car sunroofs to leak?

Leaky car sunroofs come from many causes such as weather factors, environment, equipment structure, and user usage and maintenance.

Car care and maintenance experts say that most cars equipped with sunroofs have built-in drainage pipes. In case objects such as leaves, dirt, organisms… fall into the pipe, if not detected and cleaned promptly, it will lead to clogged drainage pipes, one of the main causes of The sunroof leaking.

Next, on the sunroof, there is a drainage trough connected to the drainage pipe running along the body of the car. When this trough is covered with a lot of dirt but is not cleaned promptly, it will cause the drainage pipes to become clogged, causing water to overflow into the ceiling and leak into the interior compartment.

In addition, cars with sunroofs are designed with small holes to drain rainwater. In case the user does not use it properly or forgets to clean or maintain it periodically, it will cause dirt and objects to accumulate over a long period of time, causing a blockage, water cannot drain, and begins to gradually seep into the vehicle.

In addition, climate is also one of the factors that cause car sunroofs to leak. Due to frequent exposure to the sun and rain, especially in hot and humid tropical climates like Vietnam, the rubber gasket (which is the trough that carries water down the drain pipe) on the car will easily age, wear out, and crack over time. time. When the rubber gasket is torn, it will cause water to stagnate in the drainage ditch and seep back into the car, gradually causing a leak.
