Statute of Limitations for New Hampshire Lemon Law Claims

Timing rules for New Hampshire vehicle claims — the one-year filing deadline (RSA 357-D:11), the 40-day hearing and 30-day decision, the narrow 30-day appeal, and the CPA and Magnuson-Moss clocks.

New Hampshire’s lemon-law deadline is tied to the warranty: a consumer must commence proceedings within one year after the expiration of the express warranty term or after the manufacturer’s last repair attempt (RSA 357-D:11) — and the Arbitration Board moves fast once you file.

The one-year filing deadline

Section 357-D:11 requires the consumer to begin lemon-law proceedings within one year following the later of: the date the express warranty term expires, or the date of the manufacturer’s last repair attempt. Because the protected period itself is the warranty term plus one year, a consumer should build the claim (satisfy the presumption) within that period and file promptly.

The fast arbitration timeline

Once a complaint is filed, the New Motor Vehicle Arbitration Board holds a hearing within 40 days and issues a decision within 30 days after the hearing (RSA 357-D:5, IV). The manufacturer also gets one final repair attempt within 40 days of filing.

The narrow appeal window

Either party may appeal a Board decision to Superior Court within 30 days (RSA 357-D:6) — but the court reviews on a narrow standard (clear and convincing evidence of fraud, partiality, corruption, or the Board exceeding its authority), not a trial de novo. So the Board hearing is, in practice, the decisive proceeding.

Build the claim within the protected period

  • Satisfy the presumption (3 attempts or 30 business days) within the warranty-plus-one-year period.
  • Use the same dealer (or document good cause to switch).
  • File with the Board within one year of warranty expiration or the last repair attempt.

When the CPA and Magnuson-Moss matter

The NH CPA runs on New Hampshire’s general 3-year personal-action limitations period (RSA 508:4), and Magnuson-Moss 4 years from delivery — both outlast the lemon law’s one-year filing window, making them useful fallbacks.

Bottom line

File with the Arbitration Board within one year of warranty expiration or the last repair attempt (RSA 357-D:11); the hearing follows in 40 days and a decision in 30. The CPA (3 years) and Magnuson-Moss (4 years) are the longer-running fallbacks.
