What are the reasons why cars have difficulty starting in summer?

Possible causes of car spontaneous combustion in summer are as follows: Overheating of the braking system: The vehicle's braking system relies on friction to achieve stopping, and friction inevitably generates heat. Under high summer temperatures, the braking system faces even harsher conditions. Prolonged braking friction causes a rapid rise in temperature of the tires and brake drums, igniting the tires and leading to vehicle spontaneous combustion. This scenario is also one of the most common causes of truck spontaneous combustion in summer. Cargo spontaneous combustion: Due to high temperatures, some cargoes are prone to spontaneous combustion after prolonged exposure to sunlight. Special attention must be paid to the types of goods being transported. Vehicles carrying cotton, fabrics, or waste paper must ensure the cargo is tightly wrapped before departure, as incidents of cargo ignition by cigarette butts are frequent. Certain chemicals must be kept shaded and ventilated. It is particularly important to note that summer weather changes quickly, and vehicles transporting calcium carbide must be waterproofed; otherwise, calcium carbide will combust violently upon contact with water. Electrical system failure: Aging electrical systems, exposed wires, and contact between ground and live wires can produce sparks that ignite the vehicle's interior plastic components. Such cases of spontaneous combustion are not uncommon and have become the most overlooked and highest-rate causes of truck spontaneous combustion in summer. Especially now, with the increase in electronic devices inside trucks, many owners prefer to modify audio systems and other electronic devices themselves. These modifications involve changes to the electrical circuits, which, if not handled carefully, can easily lead to fires.
