New Hampshire Lemon Law: Your Rights

Last reviewed: June 28, 2026

New Hampshire's lemon law is run by the New Motor Vehicle Arbitration Board and covers passenger vehicles, motorcycles, and light trucks up to 11,000 pounds. If a substantial defect under warranty can't be fixed after a reasonable number of attempts, you may be entitled to a comparable replacement or a refund plus incidental damages, less a use allowance, decided by the Board.

What these rules mean for you

If your vehicle has a substantial defect that the manufacturer cannot fix after the repair attempts above, or it has been out of service for the listed time, you may have a lemon law claim. The remedy is usually a refund (a buyback) or a replacement vehicle. The details turn on your documentation, so keep every repair order from the first visit on. See what to document for a defect or lemon law claim.

A recall is not required for a claim, and recall repair attempts can count toward your total. For the full picture, read the pillar guide, recall vs. lemon law, and learn how many repair attempts before lemon law applies and how a buyback, replacement, or cash settlement compares.
