The Process: Filing a New Hampshire Lemon Law Claim
Step by step through a New Hampshire lemon-law claim — documented repair attempts, the final repair opportunity, the New Motor Vehicle Arbitration Board, and court action.
A New Hampshire lemon-law claim moves from documented repair attempts, through the manufacturer’s final repair opportunity, to the New Motor Vehicle Arbitration Board and, if needed, court — under the Lemon Law, the Consumer Protection Act, and Magnuson-Moss. New Hampshire’s arbitration is state-run by a governor-appointed board.
The path at a glance
- Document repair attempts — track the same-defect count and cumulative business days out of service (3 attempts or 30 days is the trigger), with same-dealer repair orders.
- File with the Arbitration Board — within one year of warranty expiration or the last repair attempt.
- Allow the final repair — the manufacturer gets one final attempt within 40 days of filing.
- Board hearing and decision — a hearing within 40 days, a decision within 30 days after.
- Elect your remedy or appeal — choose refund or replacement within 30 days; or appeal to Superior Court (narrow review) and/or pursue the CPA.

Two procedural keys
- The same-dealer rule + final repair — the consumer’s attempts should be documented by repair orders from the same dealer (RSA 357-D:3, VIII), and after filing, the manufacturer gets one final 40-day repair opportunity (RSA 357-D:4, V).
- State-run arbitration — the New Motor Vehicle Arbitration Board (RSA 357-D:5) decides the dispute on a fast timeline, with only narrow Superior Court review.
Why the process has teeth
Between the fast, low-cost Arbitration Board and the CPA’s double-to-treble damages and mandatory fees — triggered when a manufacturer ignores a Board decision — New Hampshire gives consumers an efficient path and strong leverage. See attorney fees.
