The motor vehicle product management is of great significance for ensuring the product quality, guiding the industrial development, standardizing the corporate management, and protecting the consumer rights and interests. This paper makes a systematic review of the safety self-certification and the environmental protection access management of the motor vehicle product management system in the United States, focusing on the regulatory objects, the main responsibilities, the legal basis and the basic procedures of the competent authorities, as well as the main characteristics of the motor vehicle management system, such as the perfect supervision system, the severe punishment, and the safety management and the mature recall system. In combination with the latest development trends, the latest development trend of our motor vehicle product management system is analyzed from the aspects of how the COVID-19 epidemics promote the optimization of the access management in the US, how the environmental protection access management becomes more open, and how the intelligent internet-connected vehicle management is accelerated.
