Why Does a Car Have Difficulty Starting?

[Aubree]

Difficulty in starting a car falls under starting faults, with common fault points as follows: Prolonged use of the car: The usage time of the car battery is the main cause of power loss. Typically, a car battery has a lifespan of two to three years. If this period is exceeded, the car is highly likely to experience power loss after being parked for two to three days, leading to weak starting. Forgetting to turn off lights and onboard electrical devices: When parking and turning off the engine, forgetting to turn off the interior lights or the air conditioning can result in the air conditioning system automatically starting up each time the ignition switch is turned on. This directly causes an instant high power load on the vehicle, which over time will wear down the battery. Starter motor damage: Worn carbon brushes inside the starter motor can cause insufficient rotation speed of the starter motor, making it harder to turn the engine's flywheel. This results in a weak starting fault phenomenon.
