Automakers must design vehicles to thrive in a broad spectrum of environments, from snowy tundra to scorching deserts. The purpose of automobile reliability test is to assess the automobile and its components. With the test chamber, it’s easy to cause the automobile failure in design, manufacturing and other aspects, directly exposing the problems and weak links. In view of this, the failure reason should be found in time, and the production should be continuously improved. Eventually, innovate design ideas, and accumulate experience for new product development.
