Massachusetts lemon law

Verified against the statute / official state publicationM.G.L. c. 90, §7N½; 201 C.M.R. 11.00

The short version

Three attempts or 15 business days — then ONE final attempt of at most 7 business days.
You may always reject a replacement and demand a refund instead.
Short fuse: everything must happen inside 1 year / 15,000 miles.

The presumption — Massachusetts's numbers

Presumption window	The term of protection is 1 year or 15,000 miles from delivery, whichever comes first.
Same defect	3+ repair attempts
Days out of service	15+ business days — 15 or more BUSINESS days out of service for any combination of defects.

The presumption is the set of numbers that shifts the burden to the manufacturer. A claim can exist outside the presumption — it is a shortcut, not the whole road. Read why.

The buyback — Massachusetts's formula

Deduction = contract price ÷ 100,000 × miles driven (figured at the acceptance of the vehicle's return). Motorcycles divide by 25,000.

Notice and procedure

After the threshold is met, notify the manufacturer and give ONE final repair attempt of no more than 7 business days — even if the term of protection has just expired.

Dispute route: State-certified arbitration through the Office of Consumer Affairs and Business Regulation (OCABR). The arbitrator fee is refunded if you win.

Attorney's fees: Massachusetts provides attorney's fees to a prevailing consumer (and Chapter 93A claims may multiply damages — a lawyer question).

Your deadline

Massachusetts's operative clocks are the term of protection (1 year / 15,000 miles) and the 7-business-day final attempt; state-certified arbitration through OCABR follows if the manufacturer refuses.

Who and what is covered

New vehicles	Covered
Leased vehicles	Covered
Used vehicles	Covered in defined situations — see notes
Motorcycles	Covered
RV / motor home	Covered — chassis / powertrain only

Motorcycles are covered (25,000 offset divisor).
Massachusetts also has a separate used-vehicle lemon law and the 'Lemon Aid' law for cars that fail inspection — the checker notes them; they are different statutes.
