Can a Car Be Damaged by Sun Exposure?

Prolonged exposure to sunlight can accelerate the aging of plastic components in a vehicle. For example, the dashboard filled with wiring, car doors, and sealing rings around the sunroof edges are particularly vulnerable. Sealing rings, in particular, are prone to aging and cracking after sun exposure, significantly reducing their sealing performance, which may lead to water leakage or seepage. Here are some items you should avoid leaving in your car during summer: 1. Lighters: Small and easy to forget, yet highly dangerous, as they contain liquid butane that can explode when internal pressure increases due to heat. 2. Bottled water: Stored in a sun-exposed car for a certain period, it can release harmful substances. Continued consumption may not only fail to quench thirst but also pose health risks. 3. Eyeglasses: Especially reading glasses, as their convex lenses can focus sunlight, potentially causing a fire. 4. Perfume (in glass bottles): The volatile components can produce flammable gases, with a critical packaging point of 49°C. Tests show that on a summer afternoon, an uncovered car can reach 65°C in just 15 minutes of sunlight, increasing the risk of explosion.

We often see cars getting damaged by the sun in summer, especially in the scorching cities of the south. Once, I parked my car on the roadside for just a few days, and when I returned, I noticed the paint on the body had started to fade. Some areas even developed tiny cracks, making it look particularly aged, as if it had endured years of weathering. The interior is another major issue—for instance, the leather seats became stiff and cracked from the sun, and the plastic on the dashboard even warped and deformed. These problems aren’t just about aesthetics; the bigger hassle is the high cost of repairs. Replacing the interior alone can cost thousands. Later, I learned to protect the paint and interior materials by using a full car cover or parking in the shade. Tires also age faster under high temperatures, as the heat makes the rubber brittle. Prolonged exposure to the sun significantly shortens tire lifespan and increases safety risks. In short, cars can indeed be damaged by the sun, so daily preventive measures are essential to keep them looking and performing their best.

I've had several unpleasant experiences with my car being exposed to extreme sunlight, so now I've developed a habit of always parking in shaded areas. The most noticeable issue is paint fading, especially on darker colors which tend to look dull and gray. Sometimes there are even small patches peeling off, requiring professional touch-ups at the shop - otherwise it's just painful to look at. The interior suffers even more: leather seats dry out and crack easily, while warped plastic components affect button functionality. These accumulated minor issues become really annoying. What worries me most is weatherstrip deterioration - once hardened and leaking, rainwater might seep into the cabin during storms. For prevention, I recommend regular application of UV-protection wax or using sunshades on windshields, which both lower interior temperature and protect surfaces. Routine checks on tire pressure and battery condition are equally important as these parts degrade faster in heat. Long-term, saving on parking fees isn't worth it compared to investing in a quality car cover that prevents costly repairs.

Yes, prolonged exposure to sunlight can damage a car, especially when the paint fades and the interior cracks, which is particularly frustrating. My old car, parked in the yard without a cover, quickly developed a whitish hue on the hood, making it look cheap. The leather seats also cracked, and I had to cover them with seat covers to barely hold them together. Replacement and repair costs are high; just one interior repair cost me hundreds. It's better to park in the shade or under a carport to reduce UV damage. High temperatures inside the car not only reduce comfort but also waste air conditioning power. Simple actions can save money and hassle.
