Most people assume they have a right to return a car within a few days of purchase — like buying anything else at a store. This is not true. There is no federal cooling-off law for car dealership purchases, and most states have no such law either. Understanding your actual rights before you sign is essential.

The Cooling-Off Rule Does NOT Apply to Car Purchases

The FTC’s Cooling-Off Rule gives you 3 days to cancel certain purchases made at your home or outside a seller’s permanent place of business. Car dealership sales — whether at the dealership or a car lot — are explicitly excluded from this rule.

Once you sign the purchase contract at a dealership, the car is generally yours. The only exceptions are voluntary dealer return policies and legal remedies.

Lemon Laws: Returning a Defective New Car

If a new vehicle has a serious defect that substantially impairs its use, value, or safety, and the dealer cannot fix it after a reasonable number of attempts, you may qualify for a remedy under your state’s lemon law:

  • Typical requirement: 3–4 repair attempts for the same defect, or the vehicle out of service 30+ days
  • Remedy options: Replacement vehicle or full refund (purchase price + incidentals)
  • Who to contact: Your state’s attorney general office or a consumer law attorney
  • Lemon laws typically do not apply to: Used vehicles, minor defects, or issues you caused

What to Do If You Want to Return a Car

  1. Check the contract — look for any return policy the dealer offered in writing
  2. Review for defects — document any issue that could qualify under lemon law
  3. Contact the dealer — some will negotiate a return or exchange to protect their reputation
  4. File a complaint — state attorney general or FTC if you believe misrepresentation occurred
  5. Consult an attorney — consumer protection attorneys often offer free consultations
