Take a look at the automotive repair industry, which encompasses car and truck maintenance and servicing. Automotive repair involves anything that requires service on a vehicle, covering its engine, transmission, drive train, axles, suspension, steering, tires, brakes, electronic system, heating and air conditioning, exhaust system, fuel line and tank, lights, and sensors. Repairs to the body of the vehicle—as is needed if it has been in an accident—is often handled by auto shops specializing in that type of restoration, known as body shops.
Automotive repair is most often done by professional mechanics in an automotive garage or the service department of a dealership, but many people choose to service their own cars and trucks—particularly for minor issues like oil changes and fluid replacement. The complexity of modern automotive systems that utilize integrated computer and electronic systems has made it more difficult for amateur mechanics to fix their own cars and trucks. Industry professionals working in private garages or at dealerships use sophisticated diagnostic equipment to determine what service is needed and the parts to use.
Vehicles come with industry manufacturer‒recommended service schedules, outlining what needs to be done, and when, in order to avoid costly repairs. This sort of service is called preventive maintenance.
