Maryland Lemon Law: Notice, Refunds, and Deadlines

If your new vehicle has a serious defect the dealer can’t fix, the Maryland lemon law lets you demand a full refund or a comparable replacement from the manufacturer. The law, found at Maryland Commercial Law §§ 14-1501 through 14-1504, covers new vehicles registered in Maryland when a substantial defect appears in the first 24 months or 18,000 miles and survives a reasonable number of repair attempts. You have three years from the delivery date to bring a claim, and you must give the manufacturer written notice by certified mail before you can force the buyback.

Vehicles and Buyers the Law Covers

Coverage runs to four vehicle classes registered in Maryland: Class A passenger cars, Class D motorcycles, Class E trucks rated at three-quarter ton or less, and Class M multipurpose vehicles. Motor homes are excluded.¹

The vehicle must be new. A “consumer” under the statute is the original purchaser of a new motor vehicle (not someone buying for resale), anyone the vehicle is transferred to during the warranty period, or anyone otherwise entitled to enforce the warranty. That last category matters if you bought a used car privately and the original factory warranty is still active: you qualify for as long as that warranty remains in force.¹

Leased vehicles are covered, but only when the lease agreement makes the lessee responsible for repairs.²

When Your Vehicle Qualifies as a Lemon

The defect has to substantially impair the use or market value of the vehicle. A transmission that slips out of gear or a persistent emissions failure would generally clear that bar. Squeaks, minor rattles, and cosmetic issues generally do not.

The problem must first appear while the vehicle is less than 24 months old and has fewer than 18,000 miles on the odometer.³ Within that window, the vehicle is presumed a lemon if any of these are true:

The manufacturer, its agent, or an authorized dealer has tried and failed to fix the same defect at least four times during the warranty period.⁴
The vehicle has been out of service for repairs for a cumulative total of 30 or more days during the warranty period. The days do not have to be consecutive.⁴
A braking or steering defect has been repaired at least once, the manufacturer was notified and given a chance to fix it, and the vehicle still fails Maryland’s safety inspection.⁴

The braking-and-steering trigger is narrower than it sounds. One failed repair alone isn’t enough; the vehicle has to actually fail the state safety inspection afterward.

The Certified Mail Notice You Have to Send First

Before you can demand a refund or replacement, you must notify the manufacturer in writing by certified mail, return receipt requested. The statute is unforgiving here: a manufacturer isn’t required to refund or replace the vehicle if the consumer fails to provide written notification and an opportunity to cure.⁴ Sending the letter by regular mail, or skipping it and going straight to a lawsuit, is one of the fastest ways to sink an otherwise solid claim.

The notice should include the Vehicle Identification Number, a description of the defect, and the repair history. The manufacturer’s mailing address is usually in the owner’s manual or on the manufacturer’s website.

Keep every repair order. Each one should show when the vehicle went in, when it came back, the symptoms you reported, and the work performed. A short personal log of when problems occur and how they affect your driving fills gaps that repair orders often leave.

What Happens After the Manufacturer Gets Your Notice

Once the certified letter is received, the manufacturer has 30 days to correct the defect at no charge to you. That obligation applies even if the repairs run past the expiration of the original warranty.⁴

If the 30-day fix fails, you have several routes. Many manufacturers offer informal dispute resolution through programs like the Better Business Bureau Auto Line. You can also contact the Maryland Attorney General’s Consumer Protection Division for help.³ Arbitration through those programs is voluntary and nonbinding on the consumer, so an outcome you disagree with doesn’t lock you in. You keep the right to sue before, during, or after arbitration.

Refund or Replacement, and How the Refund Is Calculated

When the manufacturer can’t fix the defect after a reasonable number of attempts, the choice of remedy is yours. You can demand a comparable replacement vehicle or a full refund.⁴

A refund covers the full purchase price plus all license fees, registration fees, and similar government charges. The manufacturer can subtract two things: a reasonable use allowance capped at 15 percent of the purchase price, and a reasonable allowance for damage beyond normal wear and tear (excluding damage caused by the defect itself).⁴ The 15 percent cap is a real ceiling. On a $35,000 vehicle, the most the manufacturer can take off for your use is $5,250, no matter how many miles you put on before the first repair attempt.³

If you financed the vehicle, the refund should cover the loan payoff. If you bought GAP insurance or an extended service contract at financing, contact those providers with proof of the buyback; a prorated refund of those premiums may be available once the vehicle is returned and the loan is satisfied.

The Three-Year Deadline and Bad-Faith Damages

Any legal action under Maryland’s lemon law must be filed within three years of the date the vehicle was originally delivered to the consumer. Miss that, and the claim is gone even if every element otherwise fits.

A violation of the lemon law is treated as an unfair or deceptive trade practice under Title 13 of the Commercial Law article. If the manufacturer acts in bad faith, a court can award up to $10,000 in additional damages on top of the refund or replacement value.⁵ Bad faith can look like deliberately stalling repairs past the warranty period, refusing to honor a valid claim, or failing to disclose a known defect pattern.

Federal Backup Under the Magnuson-Moss Warranty Act

Maryland’s statute isn’t your only option. The federal Magnuson-Moss Warranty Act lets consumers enforce any written warranty on a consumer product, including vehicles. Where the state law has specific repair-attempt thresholds and the 24-month/18,000-mile window, the federal act generally allows claims for up to four years after purchase.

Magnuson-Moss also shifts fees. If you prevail, the court may order the manufacturer to pay your attorney fees and court costs based on the time your attorney actually spent on the case.⁶ Maryland’s lemon law statute has no explicit attorney-fee provision, so the federal law fills the gap for consumers who can’t front a lawyer.

Federal claims also allow recovery of incidental and consequential damages, such as rental car costs, towing charges, and other expenses caused by the failure to repair. Many lemon law attorneys file state and federal claims together to reach every available remedy.

If You’re Buying Used, Check for a Lemon Buyback Title

When a manufacturer buys back a lemon, the vehicle is typically repaired and resold. Maryland requires that a buyback vehicle carry a branded title reflecting its lemon law history, and the manufacturer must provide written disclosure of the defect, the repair history, and a warning about potential ongoing issues. The brand follows the vehicle permanently. If you’re shopping used, always check the title history; a “lemon law buyback” brand means the vehicle was returned under a state lemon law, and the underlying problem is on the record even if the repair held.
