Generally, you cannot simply return a new car to a dealer in the United States because you changed your mind. Unlike many consumer goods, new vehicle purchases are considered final sales once the contract is signed. There is no federally mandated "cooling-off period" for cars. However, there are critical exceptions, primarily lemon laws and specific dealer return policies. Your ability to return the car hinges entirely on these factors.
The most powerful protection is your state's lemon law. These laws apply if your new car has a significant defect that the manufacturer fails to repair after a reasonable number of attempts. The definition of a "reasonable number" varies by state but often involves multiple repair attempts for the same issue or the car being out of service for a certain number of days. If your car qualifies as a lemon, the manufacturer is typically required to replace it or refund your purchase price.
Some dealerships or manufacturers may offer their own return programs. For example, some brands have short-term, mileage-limited return policies (like 3 days/300 miles) as a customer satisfaction guarantee. You must review your sales contract carefully to see if such a program was included. These are not legal requirements but voluntary dealer incentives.
| State | Lemon Law Coverage Period | Required Repair Attempts (for same defect) | Days Out of Service |
|---|---|---|---|
| California | 18 months / 18,000 miles | 2 attempts | 30 days |
| New York | 2 years / 18,000 miles | 4 attempts | 30 days |
| Texas | 24 months / 24,000 miles | 2 attempts | 30 days |
| Florida | 24 months / 24,000 miles | 3 attempts | 15 days |
| Illinois | 12 months / 12,000 miles | 4 attempts | 30 days |
If you simply regret the purchase, your options are limited. You can try to negotiate with the dealership, but they are under no obligation to take the car back. Your most likely path is to sell the car privately or trade it in, but be prepared for immediate depreciation, meaning you will likely lose money. The key is to act quickly, understand your specific contract, and know your state's legal protections.

Nope, a car isn't like a shirt from a department store. That signed contract is pretty much binding. Don't expect a change-of-heart return. Your best shot is if the dealer has a special return policy advertised, which is rare. Otherwise, you're looking at selling it yourself, which will cost you thousands the moment you drive off the lot. Check your paperwork first thing.

Legally, the sale is final upon signing. However, your recourse depends on the problem. Is it a minor annoyance or a major safety issue? For significant, recurring mechanical faults, your state's lemon law is your primary tool. This law forces the manufacturer to buy back or replace a chronically defective vehicle. Document every repair visit meticulously. If it's just buyer's remorse, your leverage is minimal outside of a specific dealer-promised return window.
