Does a new car need to be exposed to intense sunlight?

Generally speaking, there is no need to expose a new car to intense sunlight. Simply opening the windows for ventilation in sunlight is sufficient. New cars usually have some odors, and regular ventilation by opening the windows will help dissipate them. Besides window ventilation, there are many other methods to remove odors from a new car, such as placing bamboo charcoal bags or grapefruit peels inside the car. Car owners can choose according to their preferences and actual conditions. After washing a new car, avoid exposing it to intense sunlight, as this can affect the vehicle's paint and easily lead to paint cracking. After washing the car, just place it in a well-ventilated environment.
When I was buying a car, I also struggled with the issue of sun exposure. Exposing a new car to direct sunlight is indeed a shortcut, as high temperatures can help harmful gases like formaldehyde dissipate faster. However, prolonged exposure can really damage the car—the paint color may fade, and leather seats are prone to cracking. Back then, I chose to expose my car to the sun for two to three hours in the morning with all the windows open for ventilation, which worked well. The key is to avoid the scorching midday sun and remember to cover the car with a car cover afterward. Looking back now, natural ventilation for two to three weeks can also remove odors, so there's no need to let your beloved car get roasted like a hot plate. Electronic devices are most vulnerable to high temperatures and sun exposure—there have been quite a few cases of dashboard screens getting damaged from the heat.
I'm a mechanic at an auto repair shop, and customers often ask about sun exposure. While exposing a new car to direct sunlight can indeed accelerate the release of that 'new car smell,' the cost is high. Prolonged UV exposure speeds up paint aging, makes plastic components brittle, and causes seat fading. One customer tried sunbathing their car for a week to speed up the process, only to end up with deformed door seals. My recommendation is to park in the shade with good ventilation and simply roll down the windows for 30 minutes in the morning and evening. If sun exposure is absolutely necessary, keep the sunroof open or leave a window slightly cracked to allow heat to escape. Tires exposed to prolonged sunlight are also prone to cracking. New car owners need to strike a balance between odor removal and proper vehicle maintenance.
