New Hampshire Lemon Law Case Value Calculator

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 days, the vehicle is presumed to be a lemon. This presumption generally applies within the first 36 months or 24,000 miles of ownership.

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.

You generally have 4 years to bring a lemon law claim in New Hampshire, in line with the national average of 4.1 years. Acting before the warranty expires and while repair records are fresh protects your claim. When a vehicle qualifies, New Hampshire requires the manufacturer to repurchase or replace it rather than keep attempting repairs. Because New Hampshire's lemon law shifts attorney fees to the manufacturer when you prevail, most lemon law attorneys take these cases on contingency at no upfront cost.
