Water leaks into your Nissan's interior may arise from a variety of sources. Sunroof drains, vital for directing rainwater away, can become clogged by debris, affecting Altima, Maxima, and Murano models. Door and windshield seals, susceptible to wear, invite leaks evidenced by visible cracks or noise while driving. Clogged AC drains can lead to interior water damage, often due to accumulated dirt or mold. Trunk seal failures manifest as trunk dampness and mold, while roof racks, if improperly installed, may also permit leaks. Identifying these issues and considering repair options ensures vehicle protection and enhances understanding of preventive measures.Sunroof Drain BlockagesClogged sunroof drains in Nissan cars can cause water to leak inside, which might damage the interiors. These drains are supposed to guide rainwater away from the sunroof and out of the car.But over time, things like leaves, dirt, and dust can block them. When drains get clogged, water can't escape and might spill into the cabin, wetting carpets and seats.Models like the Altima, Maxima, and Murano sometimes face these problems. Regular check-ups can help keep the drains clear.You can use a flexible wire or an air compressor to unclog them. Some people also find success using special cleaning kits made for sunroof upkeep.If the blockage has already caused damage, getting a professional to check and fix it is a good idea. Repair costs usually range from $100 to $300, depending on how much water damage there is and the work needed.Taking steps to keep sunroof drains clear can help avoid water leaks and keep the car dry and cozy.Faulty Door SealsNissan cars can sometimes have water leaks because of worn-out door seals. These seals, made from rubber, fit tightly between the door and the car body to keep water out. Over time, they might wear out, crack, or change shape due to weather or frequent use. This can cause them not to work properly.Look out for these signs of bad door seals:Damage you can see: Cracks, tears, or warping on the seal mean it's wearing out.

This seal keeps water out of the trunk. Over time, weather can damage it, causing cracks or breaks.
