Globally, a whole vehicle warranty does not mean that every component of the vehicle enjoys the same warranty service; instead, different components are warranted separately:
Easily damaged or aging components, such as batteries, shock absorbers, wiper blades, rubber parts, and audio equipment, typically have shorter warranty periods, while components that are not easily damaged, such as engine blocks, have longer warranty periods. Furthermore, some automakers declare that certain components, such as tires, are not covered by the warranty. Therefore, the precise definition of a whole vehicle warranty should be the warranty period of the component with the longest warranty term within the vehicle. What some manufacturers refer to as an 'extended warranty' in reality only applies to specific components that are not easily damaged, while many consumers may mistakenly believe that the entire vehicle is covered by the extended warranty.
