New Jersey New Car Lemon Law: The Basics
Plain-English overview
If your brand-new car keeps breaking, NJ’s Lemon Law may force the manufacturer to refund or replace it.
It covers serious, recurring defects during the first 2 years or 24,000 miles, whichever comes first.
- 3 or more repair attempts for the same serious defect.
- 20+ cumulative days out of service for any defects.
- 1 failed attempt to fix a defect likely to cause death or serious injury.
Who Qualifies in NJ
Vehicles, timing, and issues that count
Covers new passenger vehicles purchased, leased, or registered in New Jersey for personal, family, or household use.
The defect must substantially impair use, value, or safety and must not be caused by abuse, neglect, or unauthorized modifications.
Problems and repair attempts must occur within the first 24,000 miles or 2 years after delivery, whichever comes first.
- Keep every repair order with dates, mileage in/out, and the complaint stated the same way each time.
- Warranty repairs must be performed by an authorized dealer.
- Federal recalls and routine maintenance are not Lemon Law repairs.
How the NJ Process Works
Reasonable attempts and the final chance to repair
NJ presumes a reasonable number of attempts at 3 repair visits for the same defect, 20+ days out of service, or 1 attempt for a life-threatening defect.
Before filing, you must give the manufacturer (not just the dealer) a final chance to repair.
Send a certified letter that triggers a last repair opportunity; the maker typically has 10 days to fix it.
- Send the letter by certified mail, return receipt requested.
- Include your name, VIN, mileage, defect description, repair dates, and preferred repair location.
- State that this is the final opportunity under NJ’s New Car Lemon Law.
How to File a New Jersey Lemon Law Claim
Step-by-step with the NJ Division of Consumer Affairs
You can use the state Lemon Law Unit, a manufacturer program certified by NJ, or file in court.
The state program is designed for consumers, with a filing fee and a faster hearing than a lawsuit.
- Attach proof of certified mailing and delivery of the final repair notice.
- Organize a simple timeline of dates, mileage, and days out of service.
- Bring photos, videos, and any expert reports if available.
- Gather all records: purchase/lease agreement, warranty booklet, registration, title, and complete repair orders.
- Send the final repair notice to the manufacturer and allow the last repair attempt.
- If the defect remains, download and complete the NJ Lemon Law application and checklist.
- File with the Division of Consumer Affairs Lemon Law Unit and pay the filing fee.
- Attend any inspection and the hearing; present your documents and timeline.
- Receive the decision; if you win, the remedy is a refund or a comparable replacement.
Common Mistakes to Avoid
Only complaining to the dealer and never notifying the manufacturer.
Letting repair orders use vague terms like “no problem found” without describing your safety concern.
Missing the 2 years/24,000-mile window for qualifying repairs.
Stopping documentation once the defect seems intermittent.
- Do not skip the certified final repair notice.
- Do not mix unrelated issues on a single repair order when possible.
- Do not hand over originals at the hearing—bring copies.
What to Prepare Before Getting Help
Build a winning packet
Create a binder with your contract, warranty, registration, all repair orders, correspondence, and a one-page summary.
Calculate days out of service and mileage at the first repair; NJ refunds are reduced by a reasonable use allowance.
You can still settle directly with the manufacturer at any time; get any offer in writing.
- One-page timeline with dates, mileage, and what happened.
- Copies of certified mail receipts and delivery confirmations.
- Photos/videos showing the defect or dashboard warnings.
- Names of service advisors and techs you spoke with.
- Start your timeline on the delivery date.
- Log every call or visit the same day it happens.
- Back up digital files to cloud storage.
