What are the causes of car failures?

[SanLouis]

The following are the specific reasons for car failures: 1. Presence of vulnerable parts: Some parts of the car are inherently vulnerable, such as air filter elements, spark plugs, engine oil, etc., which have a relatively short service life and need to be replaced regularly. If they are not replaced in time or are damaged prematurely, the car will malfunction. 2. Quality differences in consumables: The main consumables in a car are fuel and lubricating oil, among others. Poor quality of these additives can seriously affect the car's performance and service life, making it more prone to failures. 3. Usage environment: Highways are wide and flat, with high car speeds, making them prone to failures and accidents; uneven roads cause severe vibration and jolting, making the car more susceptible to damage. Large power consumption in mountainous areas and long waiting times in cities significantly change the car's operating conditions, making it prone to failures or sudden breakdowns. 4. Driving skills: Poor management of car usage, failure to follow break-in and regular maintenance procedures, rough starting and driving, etc., can all lead to early damage and failures in the car.
