New Jersey Used Car Lemon Law: Coverage and Claims

Yes, New Jersey has a real used car lemon law, and it covers most dealer sales of passenger cars priced over $3,000 that are seven model years old or newer, have 100,000 miles or less, and were never declared a total loss. The dealer must give you a written warranty of 90 days or 3,000 miles, 60 days or 2,000 miles, or 30 days or 1,000 miles depending on the odometer. If the dealer fails to fix the same material defect after three tries, or the car is out of service 20 cumulative days for repairs during the warranty, you may be entitled to a refund of the purchase price through the state's Lemon Law Unit.

Those figures come from the New Jersey Division of Consumer Affairs' Used Car Lemon Law page and its consumer brief (marked revised January 4, 2024), which I read on October 17, 2026, and from the regulation itself, N.J.A.C. 13:45A-26F.3. The underlying statute starts at N.J.S.A. 56:8-67, dating to 1995 and amended in 1997. The legislature's statute site would not load for our checker, so that cite stays unlinked.

Which cars the law covers, and which it does not

The law only applies to used passenger vehicles bought from a licensed dealer. The definition in 56:8-67 excludes motorcycles, motor homes and off-road vehicles, and it also leaves out a car sold at lease end to the person who leased it for more than 90 days, or to their family or employee. The consumer brief lists what falls outside: cars sold for less than $3,000, cars more than seven model years old, cars declared a total loss by an insurer, cars with more than 100,000 miles, cars not bought from a dealer, and cars sold "as is."

That "as is" line needs care. The regulation only lets a buyer waive the warranty on a car with more than 60,000 miles, and only in writing on the state's form. So a dealer slapping "as is" on a 30,000-mile, three-year-old car does not make the law go away. If you buy from a private seller, though, none of this applies. Our New Jersey private-sale title transfer guide covers that route, and our explainer on what "as is" means on a used car covers the federal side.

Warranty length by mileage

24,000 miles or less: at least 90 days or 3,000 miles, whichever comes first.
More than 24,000 but less than 60,000 miles: at least 60 days or 2,000 miles.
60,000 to 100,000 miles: at least 30 days or 1,000 miles, unless you waived it in writing.

One small annoyance: the state's own brochures round those band edges slightly differently from each other. The regulation text is what controls, and it puts a car with exactly 60,000 miles in the 30-day band. The warranty covers named parts of the engine, transmission and drive axles, including internal lubricated parts, the water pump, seals and gaskets, CV joints and axle shafts. You pay a $50 deductible for each repair of a covered item. It does not cover extended service contracts or whatever factory warranty is left.

How a claim works

You bring the car back to the selling dealer for repair during the warranty. If three attempts fail on the same defect, or the car racks up 20 days in the shop, you can apply to the Lemon Law Unit. The brief says filing there is free, compared with a $200 fee to file in Superior Court, and that you do not need a lawyer. If you hire one anyway, attorney fees are not part of your refund. If the dealer and you cannot settle, a hearing is usually set within 20 days, depending on the Office of Administrative Law's calendar. The judge's initial decision comes within 20 days of the hearing, and the Director issues a final decision within 15 days after that. A refund covers the full purchase price minus sales taxes, fees, and deductions for excessive wear and tear and personal use.

How New Jersey compares with New York

If you shop across the Hudson, our New York used car lemon law post is worth reading side by side. New York's law kicks in at a lower $1,500 price and gives longer warranties at low mileage (90 days or 4,000 miles), while New Jersey adds a seven-model-year age limit and allows 20 days in the shop where New York allows 15. Which law applies depends on the sale, so check where the dealer is licensed and where you signed.

What a history report can and cannot do here

A CARFAX or AutoCheck report does not give you any lemon law rights, and a clean one does not take any away. Where it helps is eligibility. The total-loss exclusion only applies if the dealer told you in writing before the sale, so a report showing an insurer total loss is something you want to see before you sign, not after. Our lemon law buyback title brand post explains what shows up when a car has already been bought back once. Do a free title check on NMVTIS too. And do not treat a seller's PDF as the real thing, because doctored reports are out there. CarVins is a licensed CARFAX and AutoCheck reseller with no affiliation to CARFAX, AutoCheck, Experian or the State of New Jersey. As of mid October 2026 a single report through us was about $5.50 for guests and $4.50 for members, or near $6.75 for both brands, versus $39.99 to $44.99 or so direct. Please confirm the amount at checkout.

Last thing. Once you sign, this warranty is your main protection, so do not assume there is a grace period to change your mind. Our post on when you can return a used car goes into that.
