The Massachusetts Lemon Law entitles you to a refund or a comparable replacement vehicle when a new, leased, or qualifying used vehicle has a defect that substantially impairs its use, safety, or market value and the manufacturer cannot fix it within a defined number of chances. The law sets clear triggers — a repeat defect, days out of service, a final repair opportunity — and once those are met, you can demand your money back. What follows is how the coverage works, what counts as enough repair attempts, and how to actually collect.
Which Vehicles Are Covered
New and Leased
New cars, trucks, vans, and motorcycles bought or leased from a licensed Massachusetts dealer for personal or family use qualify.1Mass.gov. Guide to New and Leased Car Lemon Law Motor homes, vehicles built primarily for off-road use, and vehicles used mainly for business are excluded.2Council of Better Business Bureaus, Inc. Standards of the Massachusetts Lemon Law
Used Vehicles
Used cars, vans, and trucks are covered under a separate warranty law with a shorter, mileage-tiered window. The vehicle must be bought from a Massachusetts dealer for personal or family use, cost at least $700, and have fewer than 125,000 miles at the time of sale.3Mass.gov. Guide to Used Vehicle Warranty Law The warranty runs:
- Under 40,000 miles: 90 days or 3,750 miles, whichever comes first
- 40,000 to 79,999 miles: 60 days or 2,500 miles
- 80,000 to 124,999 miles: 30 days or 1,250 miles
- 125,000 miles or more: no coverage
Check the odometer figure on your purchase paperwork. A used car with 65,000 miles gets you 60 days of protection, not 90.3Mass.gov. Guide to Used Vehicle Warranty Law
Private Party Sales
The dealer-based Lemon Law does not apply when you buy from a private individual. A separate rule still requires private sellers to disclose known defects that impair safety or substantially impair use. If you can prove the seller knew about a defect and hid it, you can cancel the sale within 30 days and get a refund minus 15 cents per mile driven. You can also cancel if the vehicle fails a Massachusetts inspection within seven days of purchase and estimated repairs exceed 10 percent of the price.4Mass.gov. Private Party Car Sales
The Term of Protection
For a new or leased vehicle, the defect must appear within one year of the original delivery date or before the vehicle reaches 15,000 miles, whichever comes first.1Mass.gov. Guide to New and Leased Car Lemon Law Report the problem to the dealer as soon as you notice it. Early documentation is what makes a claim work later.
When Repairs Count as “Enough”
The manufacturer gets a set number of chances before you can demand a refund or replacement. A reasonable number of attempts has been made when, during the term of protection, either of these happens:
- The same defect has been repaired three or more times and still exists or has come back.
- The vehicle has been out of service for a total of 15 or more business days for repair of any defect.
Once either threshold is crossed, the manufacturer gets one final repair opportunity capped at seven business days. That final window starts when the manufacturer first knows or should have known the threshold was reached, and it applies even if the term of protection has technically expired.5General Court of Massachusetts. Massachusetts General Laws Part I, Title XIV, Chapter 90, Section 7N1/2 If the defect still isn’t fixed after those seven days, the vehicle qualifies as a lemon.
Consumers most often skip the final-opportunity step, and skipping it hands the manufacturer a defense. Put the manufacturer on notice in writing that the three-attempt or 15-day threshold has been reached and that this is their last chance.
Notifying the Manufacturer
Before arbitration or a lawsuit, send the manufacturer written notice. Describe the defect, list every repair attempt with dates, and explain how the problem affects your use of the vehicle. Send it certified mail with return receipt requested, and keep a copy of everything.1Mass.gov. Guide to New and Leased Car Lemon Law If the manufacturer refuses to refund or replace after receiving the notice, you can move to arbitration or court.
Refund or Replacement
When a vehicle qualifies as a lemon, the manufacturer must either replace it with a comparable vehicle or issue a refund. You have the right to reject a replacement and demand the refund.5General Court of Massachusetts. Massachusetts General Laws Part I, Title XIV, Chapter 90, Section 7N1/2
What the Refund Covers
For a purchased vehicle, the refund includes the full contract price plus all credits and allowances for any trade-in. The manufacturer must also reimburse sales tax, registration fees, finance charges, dealer-added options, towing or rental costs caused by the defect, the unused portion of any extended warranty or credit insurance, and other incidental costs.6State Library of Massachusetts Archives. Consumer’s Guide to the New Car Lemon Law For a leased vehicle, the refund covers all payments you’ve made under the lease, and the lease obligation ends.
If you financed the purchase, the manufacturer typically pays the lender directly for the remaining loan balance as part of the buyback. If you’ve already paid more than the net refund amount, you receive the difference.
The Use Allowance Deduction
The manufacturer subtracts a reasonable allowance for use based on miles driven before return. Multiply the contract price by miles driven, then divide by 100,000. For motorcycles, divide by 25,000.7General Court of Massachusetts. Massachusetts General Laws Chapter 90, Section 7N1/2
On a $30,000 car driven 5,000 miles, the deduction is $30,000 × 5,000 ÷ 100,000, or $1,500. The refund would be $28,500 plus taxes, fees, and incidental costs. Miles driven while waiting for the refund also count, so delays cost you.6State Library of Massachusetts Archives. Consumer’s Guide to the New Car Lemon Law
State Arbitration
The Office of Consumer Affairs and Business Regulation runs a state Lemon Law Arbitration Program that is faster and cheaper than court. Know what it can and cannot do. An impartial arbitrator hears both sides and generally rules within 45 days. If the arbitrator finds the vehicle is a lemon, you get a full refund minus the use allowance. The arbitrator cannot order a partial refund, additional repairs, or an extended warranty. If the arbitrator rules against you, you get nothing through the program, but you keep the right to sue.8Mass.gov. Apply for Lemon Law Arbitration
When you win, the manufacturer has 21 days to pay the refund or file an appeal. Late payment or a frivolous appeal exposes the manufacturer to double damages in court.8Mass.gov. Apply for Lemon Law Arbitration
Manufacturer-Sponsored Arbitration
Some manufacturers run their own arbitration programs. You cannot be forced into one. If you choose it, the arbitrator doesn’t have to apply Lemon Law standards and can order partial refunds or other remedies the state program can’t. If you’re unsatisfied, you can still use state arbitration afterward.8Mass.gov. Apply for Lemon Law Arbitration
Going to Court
You can skip arbitration and file suit, or turn to court after arbitration fails. Claims of $7,000 or less can go to Small Claims Court without a lawyer.9General Court of Massachusetts. Massachusetts General Laws Part III, Title I, Chapter 218, Section 21 Larger claims go to District or Superior Court.
To win, you must show the vehicle had a defect that substantially impaired its use, safety, or market value, that the manufacturer had a reasonable number of repair attempts, and that the defect persisted. A consumer who wins recovers reasonable attorney’s fees and costs, which reduces the risk of hiring counsel.7General Court of Massachusetts. Massachusetts General Laws Chapter 90, Section 7N1/2
You may also have a claim under Chapter 93A, the state’s broader consumer protection statute. If a court finds the manufacturer’s conduct was willful or in bad faith, damages can be doubled or tripled, plus attorney’s fees.10General Court of Massachusetts. Massachusetts General Laws Part I, Title XV, Chapter 93A, Section 9
The Federal Fallback
If your situation falls outside the Massachusetts windows, you may still have a claim under the federal Magnuson-Moss Warranty Act. It makes breach of any written or implied warranty a federal violation and allows winning consumers to recover attorney’s fees and costs.11Office of the Law Revision Counsel. 15 USC 2310 – Remedies in Consumer Disputes It also prevents a manufacturer that offers a written warranty from disclaiming implied warranties, so the basic protection that a product should work as expected stays intact.12Federal Trade Commission. Businessperson’s Guide to Federal Warranty Law This matters most when the state term of protection has expired but the manufacturer’s own warranty is still active.
Documentation to Keep
Strong records are the single biggest factor in whether a claim succeeds. Start collecting from the day you notice a problem.
- Purchase records: sales contract, financing agreement, warranty paperwork, registration.
- Repair orders: every visit, with date, odometer reading, your stated problem, the shop’s diagnosis, and what was done. If nothing was done, get that in writing too.
- Out-of-service days: track every day the vehicle sits at the shop. The 15-day threshold is cumulative across visits.
- Correspondence: save every email, letter, and text with the dealer or manufacturer. Log phone calls with date, name, and content.
- Expenses: keep receipts for rentals, towing, rideshares, and other costs caused by the defect. These are reimbursable.
If you don’t have all the repair records, request copies from the dealer. Getting them before you file for arbitration is far easier than reconstructing them later.
