Corrosion occurs in many parts of the car and it is not only undesirable because of the problems it causes, but also reduces the resale value of the car and reduces the strength of the parts.The automotive industry is one of the important industries that are exposed to damages caused by corrosion reactions. All types of cars, due to exposure to atmospheric environment, polluting gases, and deicing salts, suffer total and partial damages in various components such as car body, internal engine components, radiator, battery, exhaust pipe, fuel tank, electrical systems, etc. Therefore, based on the importance of investigating various possible types of corrosion in automobiles, reviewing of other papers was performed in this paper. According to the statistics reported in the articles, the highest amount of corrosion is generally occured in the car engine and the type of corrosion is pitting or galvanic corrosion, although crevice and uniform corrosion can also occur in other parts of the car such as the car suspension system, fuel system, etc. Air humidity, pollutants type and content, surface humidity, and temperature can be mentioned among the factors affecting the amount and rate of corrosion in the automotive industry. It should be noted that the most common damages caused by corrosion in the engine parts include incomplete combustion and reduced efficiency, broken injectors, clogging of fuel and oil filters, as well as shorter life of used oil.

Keywords: Corrosion, Automobile, Car-body Corrosion, Deicing Salts, Corrosion in Engine, Exhaust System Corrosion.
