When Is a Car a 'Lemon' in NJ?
NJ Lemon Law defines a lemon as a vehicle with a substantial defect that the manufacturer can't repair after three attempts or 20 calendar days out of service, within the 24-month / 24,000-mile Rights Period.
The short answer: a vehicle becomes a “lemon” under the NJ Lemon Law when the manufacturer has had a reasonable number of attempts to repair a substantial defect — within the 24-month / 24,000-mile Rights Period — and the consumer has served certified-mail notice plus a 10-day final repair opportunity.
The legal test
Under N.J.S.A. § 56:12-33:
- Substantial impairment of use, value, or safety (§ 56:12-30).
- Reasonable number of repair attempts.
- Personal, family, or household use.
- Within 24 months / 24,000 miles.
- Vehicle under 10,000 lbs GVWR.
What counts as a “substantial” defect
See qualifying defects for common categories.
What counts as a “reasonable number of attempts”
Each test below is measured within the first 24,000 miles OR two years from delivery, whichever is earlier (the § 56:12-33 presumption window):
- Three or more repair attempts for the same defect, OR
- One repair attempt for a defect likely to cause death or serious bodily injury, OR
- 20 or more cumulative calendar days out of service.
NJ’s 20-calendar-day OOS threshold is tighter than the 30-day standard most states use.
The 24-month / 24,000-mile Rights Period
Matches Georgia, North Carolina, and Texas; broader than Ohio, Illinois, Pennsylvania, and Michigan.
The mandatory certified-mail notice
Even after meeting the threshold, the consumer must send certified-mail notice with a 10-day final repair opportunity before invoking remedies.
How do I know if my car qualifies?
- Multiple repair visits for the same defect.
- 20+ calendar days out of service.
- Manufacturer offering goodwill payments.
- Within the 24-month / 24,000-mile Rights Period.

What about used vehicles?
NJ has a separate Used Car Lemon Law under N.J.S.A. § 56:8-67 — see used vehicles article. Mileage-tiered coverage windows apply.
What if you’re past the Rights Period?
CFA (6-year limit with mandatory § 56:8-19 trebling) and Magnuson-Moss (4-year limit) may still apply.
