Massachusetts Lemon Law Statute of Limitations

Massachusetts’s lemon-law timing rules involve the tightest combined Lemon Law Rights Period of any state plus two longer civil-court runways.

The deadlines

Statute	Deadline	Triggered by
Massachusetts Lemon Law (§ 7N½) Rights Period	1 year OR 15,000 miles, whichever first	Original delivery date
Massachusetts Lemon Law action (§ 7N½(6))	18 months from delivery	Original delivery date
Chapter 93A (c. 260, § 5A)	4 years from accrual	Date violation occurred
Magnuson-Moss / c. 106, § 2-725	4 years from delivery	Original delivery date
Used Car Lemon Law (§ 7N¼)	Within statutory warranty period	Date of used-car sale

1-year / 15,000-mile Rights Period

This is the eligibility window for the Massachusetts Lemon Law — whichever comes first. The defect must manifest within this window. The tightest combined Rights Period of any state.

18-month Lemon Law action deadline

Under § 7N½(6), the consumer has until 18 months from delivery to file the Lemon Law action — providing six additional months beyond the Rights Period to file. The underlying defect must have manifested within the Rights Period.

Chapter 93A’s 4-year limitations period

Chapter 93A claims — 4 years from accrual under M.G.L. c. 260, § 5A. Matches NC UDTPA’s 4 years, Washington WCPA’s 4 years; shorter than NJ CFA’s 6 years or PA UTPCPL’s 6 years.

The 4-year limit extends well past the 1-year / 15,000-mile Lemon Law Rights Period — making Chapter 93A particularly important in Massachusetts.

Magnuson-Moss / c. 106, § 2-725 4-year limit

Magnuson-Moss — 4 years from delivery under Massachusetts UCC.

Used Car Lemon Law timing

§ 7N¼ Used Car Lemon Law has a sliding-scale warranty period (30/60/90 days based on mileage). Defects must manifest within the warranty period.

Practical strategy

Time since delivery	Best avenues
0 – 12 months	All open; OCABR arbitration is the fastest free path; court with c. 93A for damages amplification.
12 – 18 months	Lemon Law action filing window still open; c. 93A still available.
18 months – 4 years	Lemon Law closed; pursue c. 93A + Magnuson-Moss in court.
4+ years	Few viable options.

What to do if past the Lemon Law

1. Don’t give up — Chapter 93A’s 4-year window with mandatory § 9(4) fees and double/treble damages remains available.
2. Document the timeline carefully.
3. Talk to a Massachusetts lemon-law attorney.

Bottom line

Massachusetts’s Lemon Law Rights Period is the tightest combined window of any state, but the 18-month Lemon Law action filing window and Chapter 93A’s 4-year runway provide additional avenues. The c. 93A mandatory § 9(4) fees and § 9(3) demand-letter damages-amplification mechanism make Chapter 93A particularly important in Massachusetts cases past the Lemon Law window.
