Is it normal for the car to become damp when it rains?

It is not normal for the car to become damp when it rains. The reasons for the car becoming damp when it rains are as follows: 1. Metal is prone to rust: In a humid environment, metal undergoes oxidation reactions and is very susceptible to rust. High humidity makes the metal parts of the car more prone to rust, especially in areas where surface rust prevention is not done well. 2. Air conditioning is difficult to dry: In summer, turning on the air conditioning and directly parking in an underground parking space can make it difficult for the air conditioning to dry. Additionally, the air conditioning ventilation system, if left in a moist state for a long time, can easily breed mold and produce odors. Long-term neglect of cleaning the air conditioning system can lead to various issues and also affect health. 3. Shortened lifespan of vehicle fluids: High humidity can also shorten the lifespan of vehicle fluids, such as lubricating oil and brake fluid. High humidity can also increase the water content in fuel, making it harder to start the engine in the morning, especially in autumn.
It's usually not normal for a car to get damp when it rains. Having driven for many years, I've seen this situation often. Cars are supposed to have good seals to prevent rainwater from seeping in. The main reasons are aging or deformed rubber seals on doors or windows, or clogged drainage holes under the car due to leaves and dirt. When rainwater seeps in, the humidity inside the car increases, making it prone to mold growth. Leather seats may rot faster, and electronic components could short-circuit. In summer, if the condensate drain isn't cleaned regularly when using the air conditioning, it can also worsen the dampness. I recommend checking these areas promptly and fixing any issues early, otherwise odors and safety problems may follow. Taking it to a reliable repair shop won't cost much but will save a lot of hassle. Developing a habit of checking the seal condition before rain can prevent such troubles.
