Maryland Lemon Law: Tests, Notice & Free Car Check

The short answer

Maryland’s Lemon Law (Com. Law § 14-1501 et seq.) covers the first 18,000 miles or 24 months. Report the defect to the manufacturer by certified mail, return receipt requested. It presumes enough attempts after 4 repairs, 30 days out of service, or 1 repair of a brake or steering failure. You choose a replacement or a refund, less a use allowance of no more than 15% of the price. Sue within 3 years of delivery.

Maryland is the only state in our verified list that caps the refund deduction as a percentage of the price instead of using a mileage formula, and it has a one-repair test for brake and steering failures. This guide covers both, the certified-mail notice that starts the process and the dealer’s own duty to warn the manufacturer, using the Commercial Law Article.

Four repairs, 30 days or one brake repair in Maryland

Maryland presumes a reasonable number of attempts when, during the warranty period (the first 18,000 miles or 24 months):

1×

Brake or Steering Failure Test

A defect causing failure of the braking or steering system was repaired at least once, the manufacturer was notified and given a chance to cure, and the vehicle still fails state safety inspection rules.

Com. Law § 14-1502(d)(3)
4×

Four Repairs Test

The same defect was subject to repair 4 or more times within the warranty period and continues.

Com. Law § 14-1502(d)(1)
30

30 Days Out of Service Test

Out of service for repair a cumulative total of 30 or more days during the warranty period.

Com. Law § 14-1502(d)(2)

The defect must substantially impair the vehicle’s use and market value. The brake or steering test also needs notice to the manufacturer and a repair that still fails Maryland’s safety inspection standards.

Notice to the manufacturer in Maryland

During the warranty period, report the defect to the manufacturer or factory branch in writing by certified mail, return receipt requested, and give it a chance to cure. Repairs must be completed within 30 days of the manufacturer receiving your notice.

In Maryland you must report the defect to the manufacturer by certified mail, return receipt requested, during the warranty period.

Dispute program first. If the manufacturer has an informal dispute program complying with FTC Rule 703, you may use it before the refund or replacement remedy applies; using it does not stop you from going to court (§ 14-1502(i)).

Notice of this procedure must be disclosed to you in writing when you buy or take delivery of the vehicle.

Maryland’s 3-year deadline

Start an action within 3 years of the date of original delivery (Com. Law § 14-1502(k)).

Deadline example: new vehicle delivered March 15, 2025, with a 3-year / 36,000-mile warranty and low mileage
EventDateEffect

Protection window endsMarch 15, 2027Repairs after this date do not count toward the tests
Sue byMarch 15, 2028Start an action within 3 years of the date of original delivery

Three years from delivery is longer than the 24-month warranty period, but the repairs themselves must fall inside that period.

Maryland’s 15% cap on the use allowance

Instead of a mileage formula, Maryland lets the manufacturer deduct a reasonable allowance for use of no more than 15% of the purchase price, plus an allowance for damage beyond normal wear (but not damage caused by the defect).

Most the use allowance can be
Purchase priceMaximum use allowance (15%)
$25,000$3,750.00
$40,000$6,000.00
$60,000$9,000.00

The refund includes the full purchase price and license, registration and similar government fees, and is paid to you and any lienholder as their interests appear on Motor Vehicle Administration records.

The Maryland dealer’s duty to warn the manufacturer

Notices required under § 14-1502(f) and (g)
WhoWhenWhat
DealerWithin 7 days of the 4th repair visit for the same defect, or 20 days out of serviceNotify the manufacturer by certified mail, with a copy to the Motor Vehicle Administration
ManufacturerWithin 15 days of a vehicle being returnedTell the Motor Vehicle Administration in writing
Seller of a returned vehicleBefore resaleGive the buyer the manufacturer’s written disclosure of the return and the defect

A dealer’s failure to send its notice does not affect your rights. Your own certified letter is the step the law requires of you.

Later owners of a Maryland vehicle

A person to whom a new vehicle is transferred during the warranty is a consumer, and the rights pass to a later transferee for the duration of the warranties. The Act needs a new motor vehicle and its warranty period.

The rights pass to a later transferee for the duration of the warranties, and anyone who receives a new vehicle during the warranty is a consumer. Fleet purchases of 5 or more vehicles and motor homes are excluded.
