Dealer Sold Me a Lemon? What To Do When Your Car Breaks Down After Purchase

Dealer sold you a lemon and now the car broke down after purchase? No cooling-off period exists in SC — but as-is doesn't cover fraud. Here's what to do when the dealer won't fix your car.

You bought a used car and it broke down. Days later — sometimes the same day. The dealer says it's yours now. You drove it off the lot.
That line is half true. You signed the papers. South Carolina has no cooling-off period for vehicle purchases. You cannot return a car because you changed your mind.
But "as is" does not cover fraud. It does not cover a dealer who knew the transmission was failing and sold the car anyway. If the dealer lied to you about the car, South Carolina law gives you options.

Can I Return a Used Car to the Dealer?


Not because you changed your mind. South Carolina has no cooling-off period for car purchases — no three-day right to cancel, no matter what the salesperson implied.
But you can unwind the deal when the car has a serious defect. Under the Uniform Commercial Code, you can revoke acceptance: return the car and demand your money back. You must show the defect substantially impaired the car's value to you, that the defect existed at the time of sale, and that you acted promptly. If the dealer refuses, you sue.

Is There a Cooling-Off Period When You Buy a Car?


No. This is the myth that costs buyers their rights. Federal law gives you no cooling-off period on a vehicle purchase, and neither does South Carolina. Once you sign, the car is yours — unless the dealer broke the law selling it to you.
That is why what the dealer knew and said before the sale matters so much. The absence of a return right makes the fraud, warranty, and deceptive-practice claims the entire ballgame.

"As Is" Does Not Cover Dealer Fraud


Federal law requires dealers to post a Buyers Guide on every used car they sell. The guide states whether the car is sold "as is" or with a warranty. A dealer cannot promise you a warranty in person and hand you an "as is" Buyers Guide.
Under South Carolina law, an "as is" disclaimer must be conspicuous to disclaim the implied warranty of merchantability. Fine print buried in the contract does not cut it.
And "as is" means no warranty. It does not mean the dealer can lie. If the dealer knew about the defect and hid it, you have a fraud claim whether the sale was "as is" or not. Common dealer fraud includes hiding accident history, rolling back the odometer, advertising "one owner, no accidents" on a totaled car, covering up flood damage, and clearing a check-engine light before the sale.

What Are My Rights If an As-Is Car Broke Down?


More than the dealer wants you to believe:
Implied warranty of merchantability. When a dealer sells you a car, state law implies a warranty that the car is fit for ordinary driving. A car whose engine or transmission fails days after purchase is not fit for ordinary driving. A valid "as is" sale can disclaim this warranty — but the disclaimer has to be clear and conspicuous, and many are not.
South Carolina's lemon law covers new cars only (S.C. Code Sections 56-28-20 and 56-28-90). Used vehicles are not covered. That does not leave used-car buyers without protection.
The South Carolina Unfair Trade Practices Act. SCUTPA bans unfair and deceptive acts in commerce. Dealer fraud qualifies. You can recover actual damages — triple damages plus attorney's fees if the court finds the violation was willful or knowing. South Carolina courts have applied this law to auto dealers who failed to disclose serious vehicle defects.
Federal protections. The Magnuson-Moss Warranty Act covers written warranties and awards attorney's fees to winning consumers. Federal odometer fraud law provides the greater of treble damages or $10,000. If you financed the purchase, the FTC holder rule lets you raise the dealer's fraud as a defense against the lender collecting the loan.

Dealer Won't Fix Your Car? What To Do Now


Act fast. Evidence goes stale and deadlines run.
1. Stop driving the car if it is unsafe. Get it towed.2. Get an independent mechanic's written diagnosis. Do it this week.3. Keep everything: the contract, the Buyers Guide, advertisements, texts, emails, voicemails.4. Write down what the dealer told you, with dates.5. Do not sign new paperwork. Some dealers use spot delivery or yo-yo financing — they call you back to sign a worse deal after you took the car home. You are not required to sign.6. File a complaint with the South Carolina Department of Consumer Affairs.7. Talk to a consumer lawyer before you make another payment on a car that does not run.
The "it's yours now" line counts on you giving up. Most buyers do. The ones who document and act quickly get results.
