How can you return a new car?

You can return a new car to a dealership if the vehicle meets state "lemon law" requirements, which vary from state to state. The buyer's right to return a defective new car is not found in the federal lemon law but exists because every state has its own motor vehicle warranty law. State lemon laws may define a "lemon" as a car with repeated defects that cannot be fixed, with a substantial number of defects, with the defect(s) significantly reducing the car's value or use, or with defects that have created a safety risk. Returning a new car to the dealer is a process that can be complex and time-consuming and usually requires written notifications and repair attempts as well as meeting the other requirements of the state's lemon law.
