New Hampshire Lemon Law Buyback Calculator

In New Hampshire, a lemon law buyback (repurchase) refunds what you paid for the vehicle minus an allowance for the use you got from it. New Hampshire RSA 357-D:3, V sets that allowance as the full purchase price multiplied by the miles the vehicle traveled before the first repair attempt, divided by 100,000 (20,000 or 40,000 for a motorcycle, snowmobile or OHRV, depending on engine size). Illustration only: 6,000 counted miles on a $35,000 price is an allowance of $2,100. Our calculator applies the 100,000-mile divisor to the mileage you enter for when the defect first appeared, so treat its figure as an estimate: the statute's own count of miles controls, and a licensed attorney can confirm how it applies to your purchase or lease.

New Hampshire recognizes a "lemon presumption" that shifts the burden to the manufacturer once your repair history crosses set thresholds. If the dealer cannot fix the same substantial, warranty-covered defect after 3 repair attempts, or if the vehicle is out of service for a cumulative 30 business days, the vehicle is presumed to be a lemon. In New Hampshire this presumption counts repair attempts made within the express warranty term and business days out of service during the term of the express warranty; the statute sets no separate month or mileage window (New Hampshire RSA 357-D:3).

New Hampshire's state lemon law generally covers new vehicles purchased with a manufacturer's warranty. If your vehicle is used or falls outside the state statute, you may still have a claim under the federal Magnuson-Moss Warranty Act, which applies to written warranties nationwide.

New Hampshire RSA 357-D:11 requires a lemon law proceeding to be commenced within 1 year following the later of the expiration of the express warranty term or the manufacturer's final repair attempt of the defect that led to the request for a replacement or refund, so the deadline depends on the length of your manufacturer's warranty and on your repair history. A licensed attorney can confirm which deadline applies to your vehicle. When a vehicle qualifies, New Hampshire requires the manufacturer to repurchase or replace it rather than keep attempting repairs. New Hampshire's lemon law lets the court award attorney fees to a consumer who wins (New Hampshire RSA 357-D:10); whether to award them is up to the court.
