When a car is a lemon in Delaware

Within the warranty term or 1 year from delivery (whichever ends first), your car is presumed a lemon if: (1) substantially the same defect was repaired 4 or more times and still exists; or (2) the car was out of service for repairs a total of more than 30 calendar days, counted from the first day you bring it in and the shop writes up the problem. The defect must substantially impair the car's use, value, or safety. The presumption only works against the manufacturer if it first got direct written notice from you (or someone for you) and had a chance to fix the defect.

Period: The manufacturer's express warranty term or 1 year from original delivery, whichever ends first. There is no mileage limit in the law.

Yes
Used vehicles
No
Leased vehicles
Not specified
Which vehicles
New passenger motor vehicles bought or leased in Delaware or registered by the Delaware Division of Motor Vehicles. The living quarters of motor homes are excluded.
Who can claim
The buyer (not someone buying to resell), anyone the car is transferred to while the manufacturer's express warranty is still in effect, and anyone else entitled to enforce the warranty.

Notice to the manufacturer

Send the manufacturer direct written notice of the defect and give it a chance to repair it. The law does not require a specific delivery method such as certified mail.

Write your notice letter below.

Arbitration

Delaware has no state-run program. If the manufacturer's informal dispute program has an annual certificate of approval from the Attorney General's Consumer Protection Unit, you must use it first; if not, you can go straight to court. Certified programs must hold hearings in Delaware and decide within 65 days. The Consumer Protection Unit lists American Honda Motor Company as a registered manufacturer.

What you can get

Your choice of a comparable new replacement acceptable to you or a repurchase; you have the unqualified right to refuse a replacement and demand a refund. A refund covers the full purchase price, including credits and allowances for any trade-in, plus related purchase costs such as sales tax, registration fees, and dealer preparation fees. The manufacturer may subtract a use allowance of no more than purchase price × (miles driven before you first reported the defect ÷ 100,000), plus an allowance for damage beyond normal wear and tear not caused by the defect.

Attorney fees: Yes, at the court's discretion. The court may award you costs and reasonable attorney fees in a lemon law suit (6 Del. C. § 5005).

Used cars in Delaware

The Attorney General says the Delaware Lemon Law applies only to new vehicles. Delaware has no separate used-car lemon law.
