Cars can indeed develop issues when exposed to high temperatures. The specific problems caused by prolonged sun exposure are as follows: 1. Tires: When the weather gets hot, the tire pressure of the car increases. This raises the risk of a tire blowout, which is why cars are more prone to blowouts in summer. The simplest solution is to slightly reduce the tire pressure. The standard tire pressure for most cars is around 2.5. If the tire pressure exceeds this value, combined with hot weather and high-speed driving, the friction will further increase the tire pressure, making blowouts even more likely. When refilling tires in summer, try to do it around noon to minimize the impact of rising temperatures on tire pressure. 2. Paint: Modern car paint is primarily composed of epoxy resin, which has a heat resistance of at least 120°C. Under normal conditions, even with sunlight, the car body temperature won't exceed 100°C. The real damage to the paint comes from ultraviolet (UV) rays in sunlight. Since the resin in the paint is an organic component, it naturally ages over time, and sunlight accelerates this process. To mitigate this, using a car cover or parking in a shaded underground garage can help reduce UV damage. 3. Interior: While the car's air conditioning protects the interior when the car is running, once the AC is turned off and the car is left in the sun, the heat and sunlight begin to damage the interior materials. Besides leather, fabric, and other organic materials, many joints in the car are held together with adhesives. After prolonged exposure to high temperatures, the interior releases harmful chemicals like formaldehyde and benzene at an accelerated rate. Often, when you open the car door, the strong, pungent smell you notice is likely due to these harmful gases.

Leaving a car exposed to extreme heat will definitely cause problems, something I’ve personally experienced during summer parking. Once, I parked outside for an entire day under the sun, and when I got back inside, the heat was unbearable—it felt like a steamer. The seat surfaces were hot enough to scald skin, plastic interior parts started warping and peeling, and even tiny cracks appeared on the roof. What’s worse, the AC couldn’t cool the car down even at full blast, fuel consumption spiked, and during one trip, the battery died and left me stranded, forcing me to call a tow truck. Over time, prolonged exposure not only fades the paint but also causes interior materials to release harmful gases, affecting health. Now, I make sure to park in shaded spots or underground garages, use a sunshade cover, and always check the battery and AC before trips. These small precautions help extend the car’s lifespan and save a lot on repairs.

Leaving your car exposed to high temperatures under the scorching sun is definitely problematic, as I've experienced multiple times. For instance, the tires age faster in the heat, increasing the risk of sudden blowouts while driving on the highway, so it's essential to regularly check tire pressure and wear. Interior components, like the dashboard and door handles, are prone to warping and becoming sticky, which feels unpleasant and releases unpleasant odors, affecting your driving mood. The battery is also more likely to malfunction, and if the cooling system isn't efficient, engine overheating warnings are common—in severe cases, the cooling system may even leak. To avoid these issues, I make it a habit to leave the windows slightly open for ventilation before parking to reduce heat buildup inside the car. Regular maintenance is also crucial, especially checking whether the air conditioning system is functioning properly. When driving in hot weather, safety comes first—don't let the sun ruin your beloved car or your wallet.

Cars are bound to have problems under high-temperature exposure, as I've personally observed many times. The most common issues are the accelerated aging of plastic and leather materials inside the car under heat, releasing irritating odors that are harmful to the respiratory system. The air conditioning system is forced to operate at full capacity, leading to reduced efficiency and increased fuel consumption. The battery and wiring are also affected, potentially causing short circuits or starting failures. I recommend using sunshades or parking in shaded areas whenever possible, ventilating the car frequently to dissipate heat, and maintaining the health of interior components.
