However, there are a few exceptions to this rule. For example, if you knowingly concealed a major defect in the car, such as a faulty engine or transmission, the buyer may be able to sue you for fraud. Similarly, if you made any false or misleading statements about the car, the buyer may be able to sue you for breach of contract.
In addition, some states have laws that protect consumers who purchase used cars. For example, in California, the Song-Beverly Consumer Warranty Act requires used car dealers to provide buyers with a warranty that covers certain repairs for a specific period of time. If you sell a used car privately in California, you are not required to provide a warranty, but if you do, it must comply with the Song-Beverly Act.
If you are concerned about being sued after selling a used car, you should consult with an attorney to learn about the laws in your jurisdiction.
