New Jersey Lemon Law Guide: Your Rights Under New Jersey Lemon Law

What Is the New Jersey Lemon Law? The New Jersey Lemon Law, codified at N.J. Stat. Ann. § 56:12-29 et seq., provides statutory protections to consumers who purchase or lease new motor vehicles that fail to conform to the manufacturer's express warranty. The law is designed to require manufacturers to repair defects that substantially impair the vehicle's use, market value, or safety or to provide an appropriate remedy—typically a replacement vehicle or full refund—if the defect cannot be repaired in a reasonable time. New Jersey's statute creates a streamlined process for consumers and manufacturers that emphasizes prompt repairs and, when necessary, an administrative remedy through a manufacturer-provided arbitration program. The New Jersey Division of Consumer Affairs administers information and consumer guidance on this process see the official consumer site at https://www.njconsumeraffairs.gov/lemon/. Because the Lemon Law interacts with the vehicle's written warranty and federal consumer warranty protections, many claims also invoke federal statutes such as the Magnuson-Moss Warranty Act. You can read a plain-language overview of the federal law and how it complements state rights in our guide to the Magnuson-Moss Warranty Act/resources/magnuson-moss-warranty-act/. Which Vehicles Qualify Under New Jersey Lemon Law? New Jersey's Lemon Law applies only to new passenger motor vehicles that are purchased or leased with an express warranty from a manufacturer. The statute explicitly excludes used vehicles that are not covered by the manufacturer's new-vehicle warranty. Coverage begins on the date of delivery to the first retail purchaser and is limited by time and mileage. The standard coverage period under the statute is 24 months or the first 24,000 miles on the odometer, whichever comes first. During that period, any condition that substantially impairs the vehicle's use, safety, or market value and cannot be repaired after a reasonable number of attempts may qualify the vehicle as a “lemon” under the statute. Other vehicle categories — such as commercial vehicles, certain multiple-use vehicles, or vehicles not originally sold for highway use — may be treated differently under specific statutory language or the manufacturer’s warranty terms. If you are uncertain whether your vehicle qualifies, review the warranty paperwork and consult the New Jersey Division of Consumer Affairs guidance at https://www.njconsumeraffairs.gov/lemon/ or a qualified attorney. How Many Repair Attempts Are Required in New Jersey? Under N.J. Stat. Ann. § 56:12-29 et seq., a vehicle may be presumed to be a lemon if the same defect has been subject to a reasonable number of repair attempts or if the vehicle has been out of service for a cumulative number of days. New Jersey provides specific thresholds the consumer and manufacturer commonly use as benchmarks. | Condition | Presumption Threshold | Statutory Reference / Notes | |---|---:|---| | Same defect re
