New car failures and 4S shops mainly have the following solutions: 1, negotiation: In general, as long as the failures are caused by objective reasons, they are generally quality problems of manufacturers. At this time, the owner can directly explain the situation in the 4S shop and negotiate with the 4S shop for maintenance or replacement. 2. Complaint handling: If there are obstacles in the negotiation process, the owner can call the manufacturer's after-sales phone to ask for handling and reflect the situation. Of course, car owners need to provide relevant evidence of vehicle quality problems, which makes it easier to defend their rights.
