It is not good for a car to be exposed to the sun for a long time, as it can cause the following effects: 1. Ultraviolet rays in sunlight can cause the plastic parts of the vehicle to age; 2. The sealing rings of the windows will age and crack, leading to water leakage and seepage; 3. It can increase the formaldehyde content in the air inside the car, which is harmful to human health; 4. It can accelerate the fading of the vehicle's paint. If a car stays in a high-temperature environment for a long time, its heat dissipation ability will deteriorate, and the engine's own temperature will rise more easily, leading to a decline in performance. When the battery temperature rises, the negative electrode may develop problems due to the aging of the insulation layer.
From my years of driving experience, prolonged exposure to sunlight is definitely not good for cars. The paint fades quickly—for example, black turns into light gray—not only affecting the appearance but also causing the resale value to plummet. The interior suffers even more: leather seats are prone to drying and cracking under intense sun, while plastic components like the steering wheel and dashboard may bubble or warp, emitting an unpleasant plastic smell when you get in. Tire rubber deteriorates faster, increasing the risk of skidding in summer and compromising safety. The battery also overheats, shortening its lifespan and leading to costly repairs. I always try to park in a garage or under shade—a simple sunshade cover can save a lot of hassle. Otherwise, the repair costs over a year could easily add up to the price of new parts.
