New Hampshire lemon law

Verified against the statute / official state publicationRSA 357-D (New Motor Vehicle Arbitration); RSA 357-C:3 definitions

The short version

No month/mile cap — the warranty term is the window.
You must ELECT your forum in the notice letter, and the election is binding.
The motorcycle deduction divisors (40,000 / 20,000) are unique to New Hampshire.

The presumption — New Hampshire's numbers

Presumption window	New Hampshire has no month/mile cap in the lemon law itself: the attempts must occur within the express warranty term.
Same defect	3+ repair attempts
Days out of service	30+ business days — 30 or more BUSINESS days out of service. Attempts must be evidenced by written repair orders, at the same dealer unless you show good cause.

The presumption is the set of numbers that shifts the burden to the manufacturer. A claim can exist outside the presumption — it is a shortcut, not the whole road. Read why.

The buyback — New Hampshire's formula

Deduction = full purchase price × miles traveled before the FIRST repair attempt ÷ 100,000. Motorcycles: ÷ 40,000 (over 250cc) or ÷ 20,000 (250cc or smaller).

Notice and procedure

After the 3rd attempt or 30 business days out, notify the manufacturer in writing and ELECT your forum: the manufacturer's dispute program or the state Motor Vehicle Arbitration Board. The election locks out the forum you didn't pick.

Dispute route: The NH Motor Vehicle Arbitration Board is a state forum: $50 filing fee, hearing within 40 days, decision enforceable against the manufacturer.

Attorney's fees: New Hampshire provides attorney's fees to a prevailing consumer.

Your deadline

Request arbitration within 3 years of original delivery (NH Dept. of Safety guidance). Board fee: $50 for the consumer ($250 for the manufacturer); the hearing is held within 40 days, and the manufacturer gets one final repair attempt inside that window.

Who and what is covered

New vehicles	Covered
Leased vehicles	Covered
Used vehicles	Covered in defined situations — see notes
Motorcycles	Covered
RV / motor home	Covered — chassis / powertrain only

Motorcycles are covered, with their own offset divisors: 40,000 (over 250cc), 20,000 (250cc or under). One national statute mirror prints 45,000 for the large-bike divisor; the RSA text and two other mirrors read 40,000, which is what we use.
Keep making your loan or lease payments — stopping payment forfeits the remedy.
