New Jersey Lemon Law Buyback Calculator

A New Jersey 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.

New Jersey 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 20 days, the vehicle is presumed to be a lemon. This presumption generally applies within the first 24 months or 24,000 miles of ownership.

New Jersey is among the states whose lemon law extends to qualifying used vehicles sold with a manufacturer's warranty, not just new cars.

New Jersey's lemon law (N.J.S.A. 56:12-29 to 56:12-49) states no deadline of its own for filing a lawsuit, so this page gives no single number. New Jersey's Uniform Commercial Code requires an action for breach of any contract for sale to be commenced within 4 years after the cause of action accrues (N.J.S.A. 12A:2-725). A breach of warranty occurs when tender of delivery is made, unless the warranty explicitly extends to future performance and discovery of the breach must wait for that performance, in which case the claim accrues when the breach is or should have been discovered. Which deadline applies to a claim under the lemon law itself is not settled by these statutes. The New Jersey Division of Consumer Affairs states an earlier step in its New Car Lemon Law brief: before a claim can be filed with the Division, the manufacturer must be given one final chance to repair by a letter sent by certified mail, return receipt requested, and that letter must be received by the manufacturer before the odometer reaches 24,000 miles and within 2 years from delivery. Act promptly, before the odometer reaches 24,000 miles and well within 2 years from delivery (the earliest limits named here), while repair records are fresh; a licensed attorney can confirm which deadline applies to your vehicle. When a vehicle qualifies, New Jersey requires the manufacturer to repurchase or replace it rather than keep attempting repairs. New Jersey's lemon law provides for an award of attorney fees to a consumer who wins (New Jersey Statutes 56:12-42).
