Under the New Jersey Lemon Law (N.J.S.A. 56:12-29 and following), a new motor vehicle qualifies as a "lemon" if a defect that substantially impairs its use, value, or safety is not fixed after a reasonable number of repair attempts during the first two years from the date of delivery or the first 24,000 miles, whichever comes first. New Jersey defines "reasonable" with a legal presumption: the manufacturer is presumed to have had enough chances once the same defect has been subject to three or more repair attempts, or once the vehicle has been out of service for repair for a cumulative total of 20 or more calendar days. For a serious safety defect involving the braking or steering system, a single failed repair attempt can be enough. If the defect still is not corrected, you are entitled to a full refund or, if you prefer, a comparable replacement vehicle.
Which Vehicles and Defects Qualify
The new-car Lemon Law covers passenger vehicles, motorcycles, and authorized emergency vehicles that are purchased, leased, or registered in New Jersey and are still within the protection period. It applies to defects that are covered by the manufacturer's express warranty and that substantially impair the use, value, or safety of the vehicle. Minor irritations, cosmetic issues, or problems caused by owner abuse, accident, neglect, or unauthorized modifications are not covered.
The protection period runs for the first 24 months or 24,000 miles, whichever occurs first, measured from the original delivery date to the consumer. A defect must first be reported to the dealer or manufacturer within that window, although the repairs and the final remedy can extend beyond it.
The Repair-Attempt and Days-Out-of-Service Triggers
Three repair attempts for the same substantial defect, or
20 cumulative calendar days out of service for repair of one or more substantial defects, or
One repair attempt for a defect that is likely to cause death or serious injury if the vehicle is driven (a serious braking or steering safety defect).
Meeting any of these creates a presumption that the manufacturer has had a reasonable opportunity to repair. The manufacturer can try to rebut that presumption, but the burden shifts to it once you document that a trigger was met.
The Required Final Notice
Before you are entitled to a refund or replacement, New Jersey requires you to give the manufacturer one last chance. After the third repair attempt or the 20th day out of service, you must notify the manufacturer in writing by certified mail, return receipt requested, of the continuing defect. The manufacturer then has one final repair opportunity, which may not exceed 10 calendar days after receiving your vehicle. Keep a copy of the letter and the certified-mail receipts, because this step is a precondition to your remedy.
What You Recover: Refund or Replacement
If the defect persists after the final opportunity, the manufacturer must, at your option, either replace the vehicle with a comparable one or refund the full purchase price. The choice belongs to the consumer, not the manufacturer. A qualifying refund generally includes:
The full purchase or lease price, including factory and dealer-installed options;
Sales tax, license and registration fees, and other government charges; and
Reasonable incidental costs such as towing and rental.
The manufacturer may subtract a reasonable allowance for the consumer's use of the vehicle. New Jersey calculates this offset based on the mileage at the time the vehicle was first brought in for the defect, using a statutory formula tied to the purchase price and a 100,000-mile expected vehicle life. The deduction is limited to use before the first repair, not the entire time you owned the vehicle.
The Used Car Lemon Law
New Jersey also has a separate Used Car Lemon Law (N.J.S.A. 56:8-67 and following). It applies when you buy a used vehicle from a New Jersey dealer for at least $3,000 and with 100,000 miles or fewer at the time of sale. The dealer must provide a written warranty whose length depends on the odometer reading at purchase:
24,000 miles or fewer: 90 days or 3,000 miles, whichever comes first;
24,001 to 60,000 miles: 60 days or 2,000 miles;
60,001 to 100,000 miles: 30 days or 1,000 miles.
During that warranty the dealer must repair covered defects. If the same defect is not fixed after three attempts, or the vehicle is out of service for 20 or more cumulative days, you may be entitled to a refund minus a mileage allowance. Private-party sales and "as is" deals on vehicles below the price or above the mileage thresholds generally are not covered.
How to Enforce Your Rights
Keep every repair order, work invoice, and communication, and make sure each document accurately describes the defect and the dates the vehicle was in the shop. You have two main enforcement paths. First, you can use the state-administered Lemon Law dispute-resolution program run by the New Jersey Division of Consumer Affairs, which offers a relatively fast hearing before a neutral decision-maker. Second, you can file a lawsuit in Superior Court; the Lemon Law allows a prevailing consumer to recover attorneys' fees and court costs, which makes it easier to find counsel.
You generally must bring a Lemon Law claim within a limited time after the protection period or warranty ends, so do not wait. If you also financed the vehicle, continue making payments where required while you pursue your claim, because stopping payments can trigger repossession and damage your credit independent of the defect dispute.
Where to Verify and Get Help
The Lemon Law is administered by the New Jersey Office of the Attorney General, Division of Consumer Affairs, Lemon Law Unit. That office publishes the current application forms, the dispute-resolution procedures, and the exact mileage-allowance formula, and it can answer questions about whether your vehicle qualifies. Because filing fees, forms, and program details can change, confirm the current figures and deadlines with the Division of Consumer Affairs before you file.
How New Jersey Compares to Federal Law
On top of New Jersey's statute, the federal Magnuson-Moss Warranty Act gives consumers nationwide the right to enforce written and implied warranties and to recover attorneys' fees in a successful suit. The federal law does not set a specific repair-attempt count or buyback formula the way New Jersey does, so the state Lemon Law usually gives you stronger, more concrete rights for a defective new or qualifying used vehicle. You can often pursue both together.

Frequently asked questions
How many repair attempts trigger the New Jersey Lemon Law?
New Jersey presumes the manufacturer had a reasonable chance to repair after three or more attempts at the same substantial defect, or after the vehicle has been out of service for repairs for 20 or more cumulative calendar days. A single failed repair of a serious braking or steering safety defect can also qualify.
What is New Jersey's Lemon Law time and mileage limit?
The new-car Lemon Law covers defects reported during the first two years from the delivery date or the first 24,000 miles, whichever comes first. The defect must first be reported within that period, though repairs and the final remedy can extend beyond it.
Can I choose a refund instead of a replacement vehicle in New Jersey?
Yes. When a vehicle qualifies, the remedy is at the consumer's option. You may demand a full refund of the purchase price, taxes, and fees, minus a statutory mileage-use allowance, rather than accept a replacement vehicle.
Does New Jersey's Lemon Law cover used cars?
A separate Used Car Lemon Law covers vehicles bought from a New Jersey dealer for at least $3,000 with 100,000 miles or fewer. The dealer must give a warranty of 30 to 90 days depending on mileage, and unfixed defects can entitle you to a refund.
Do I have to notify the manufacturer before getting a refund?
Yes. After the third repair attempt or 20 days out of service, you must notify the manufacturer in writing by certified mail, return receipt requested, and allow one final repair attempt of up to 10 calendar days before claiming a refund or replacement.
