The recall of automobiles has long been a new issue in the United States, Europe, Japan, South Korea and other countries.
U.S.: Longest history, tightest management procedures
The longest history of recalls is related to the most stringent management procedures. The United States began recalling defective cars as early as 1966 (the competent authority is the National Highway Traffic Safety Administration (NHTSA) of the United States). To date, the United States has recalled more than 200 million vehicles and more than 24 million vehicles. Tires. The models involved include cars, trucks, buses, and motorcycles. Nearly all automobile manufacturers worldwide have experienced recalls in the United States. In these recall cases, most were voluntarily recalled by manufacturers, but some were also recalled by NHTSA because of NHTSA's influence or NHTSA's forced enforcement by the court. U.S. law requires that if a car manufacturer finds a safety defect, it must notify NHTSA and the owner, seller, and agent before proceeding with free repair. NHTSA is responsible for supervising the manufacturer's repair measures and recall process to ensure that the restored vehicle can meet the statutory requirements.
Japan: Writing a recall into the Law on Road Transport Vehicles
Since 1969, the implementation of the automobile recall system began. In 1994, the recall was written into the "Road Transport Vehicles Act." It was further revised and improved in 2002. As of 2001, Japan had recalled 34.83 million defective vehicles, and recalled 3.29 million vehicles in 2001 alone. Among them, most of them are automatically recalled by enterprises according to law. South Korea: Public awareness of quality continues to increase
Since the recall of cars started in 1992, only 1,100 cars were recalled in the same year. Both the car manufacturers and the owners did not know the recall well. However, as the government's requirements for vehicle safety have become more stringent, owners’ awareness of their rights has continued to increase, and the number of recalls has continued to increase. By the year 2000, the number of recalls had increased to 560,000, 570,000 in 2001 and 1.29 million in 2002. This does not mean that the quality of cars has dropped, but that the public’s sense of quality has improved.
