Why does a car start by itself?

It is likely an issue with the car's alternator and battery. When starting, almost all the electricity is directed to the starter motor, leaving insufficient voltage for other electrical devices. It is recommended to have the car's starter motor and battery checked. Below is an introduction to car starting: The function of the starting system is to convert the electrical energy from the battery into mechanical energy through the starter motor to start the engine. Modern car engines use an electric motor as the starting power source. The system consists of the battery, ignition switch, starter relay, and starter motor.

I've been driving for over twenty years and have encountered quite a few cases of car fires. The most common causes of spontaneous car combustion include electrical short circuits, fuel system leaks, or battery failures. Worn or aged wiring is prone to short circuits, and combined with high temperatures, can spark a fire. Additionally, if your car's engine compartment accumulates a lot of dry leaves or oil stains, it's also susceptible to spontaneous combustion under high heat. Prevention is simple: regularly clean the engine area and check for cracks or looseness in the wiring and fuel lines. If you notice smoke, never use water to extinguish it—use a fire extinguisher or evacuate immediately. Older cars require extra caution; it's best to conduct a comprehensive inspection annually. Safety should always come first.
