12315 can handle used car complaints. When used car disputes arise, first negotiate compensation issues privately. If negotiation fails, you can call the 12315 consumer complaint hotline for assistance, or file a complaint with the local industrial and commercial administration department, which will investigate and mediate the dispute. If mediation is unsuccessful, you can also protect your rights through legal channels by filing a lawsuit in court. If the seller concealed information or committed fraud that prevents transfer registration, you may request refund plus triple compensation according to law. Specific regulations are as follows: 1. The used car seller should provide the buyer with truthful information about the vehicle's usage, repairs, accidents, inspections, mortgage registration status, tax payments, and retirement period. 2. After the transaction is completed, the seller should promptly deliver the vehicle, license plates, and legal documents to the buyer. 3. Legal vehicle documents refer to the 'Motor Vehicle Registration Certificate', 'Motor Vehicle Driving License', valid motor vehicle safety inspection certificate, vehicle purchase tax payment certificate, road maintenance fee payment certificate, vehicle and vessel tax payment certificate, and vehicle insurance policy.
