What Could Be the Reason When a Car Fails to Start Despite Everything Appearing Normal?

[OZoey]

There are two scenarios when a car fails to start: Battery Depletion: When the car battery is depleted, the vehicle may fail to start. Several factors can lead to battery depletion, such as insufficient battery water, battery malfunction, or prolonged use of the air conditioning. If the car doesn't start, the first step is to check whether the battery is the issue and identify the specific problem before sending it to a 4S shop for repair. Extremely Low Temperatures: During cold winter weather, cars often have difficulty starting. This is because, in low-temperature environments, the viscosity and rotation speed of the car's engine oil decrease, leading to reduced ignition energy from the battery and decreased molecular activity. As a result, flammable gases cannot form, making it difficult for the car to start.
