1. Contact the 4S store: First, you can contact the 4S store to explain that the vehicle information is wrong and ask them to solve the problem. If it's their fault, they may offer some solutions, such as replacing the vehicle or getting a refund.
2. Complain to the consumer association: If communication with the 4S shop is not smooth, you can complain to the local consumer association. Consumers' associations can help you resolve disputes and urge 4S shopping malls to take necessary measures.
3. Seek legal aid: If the above two methods can't solve the problem, you can seek legal aid. You can consult a lawyer or seek the help of relevant legal institutions to safeguard your rights and interests.
In short, if you find that the vehicle information is wrong, you should take timely action to safeguard your rights and interests. When dealing with such problems, relevant evidence, such as car purchase contract and vehicle registration certificate, should be kept for subsequent treatment.
