Massachusetts Lemon Law Case Value Calculator
A Massachusetts lemon law buyback centers on the vehicle's purchase price, reduced only by a mileage offset for pre-defect use. That offset is generally figured as (miles at first repair attempt ÷ 120,000) × purchase price. For a $40,000 truck with 9,000 miles when the defect first appeared, the offset is about $3,000, leaving roughly $37,000 in refundable purchase price before incidental damages such as sales tax, license fees, and finance charges are added back.

How Massachusetts Law Affects Your Lemon Law Case
Massachusetts 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 15 months or 15,000 miles of ownership.
Massachusetts is among the states whose lemon law extends to qualifying used vehicles sold with a manufacturer's warranty, not just new cars.
You generally have 4 years to bring a lemon law claim in Massachusetts, 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, Massachusetts requires the manufacturer to repurchase or replace it rather than keep attempting repairs. Because Massachusetts'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.
