If your new car keeps breaking down under warranty, the Massachusetts lemon law for new vehicle consumer protection and repair standards is your safety net. This law forces manufacturers to fix, replace, or refund a defective vehicle if it can’t be repaired after a reasonable number of attempts.
As of 2026, the law covers new cars, trucks, and motorcycles for 1 year or 15,000 miles, whichever comes first. If your vehicle meets the criteria, you could be entitled to a full refund or a replacement.
Quick Answer
The Massachusetts lemon law for new vehicle consumer protection and repair standards applies to new vehicles with substantial defects. It requires manufacturers to repair issues within 3 attempts or 15 days out of service. Coverage lasts 1 year or 15,000 miles.
Eligible consumers can seek a refund or replacement.
How the Massachusetts Lemon Law Protects You
This law prevents manufacturers from dragging out repairs or ignoring serious defects. If your car has a problem that substantially impairs its use, value, or safety, the manufacturer must fix it under warranty.
The law also ensures you’re not stuck with endless repair attempts. If the issue persists after 3 tries, or if the car is out of service for 15+ cumulative days, you can demand a buyback or replacement. For safety defects, even one failed repair attempt may be enough.
What Counts as a “Lemon” Under MA Law?
A lemon is a new vehicle with a non-conformity, a defect that substantially impairs its use, value, or safety. This includes persistent engine issues, transmission failures, or electrical problems that the dealer can’t fix.
Not every issue qualifies. Minor problems like a squeaky door or a loose trim piece typically don’t meet the threshold. The defect must be serious enough to make the car unreliable or unsafe.
The 3 Repair Attempts (or 15 Days) Rule Explained
The law sets clear thresholds for when a vehicle is considered a lemon. If the same defect isn’t fixed after 3 repair attempts, you can file a claim. Alternatively, if the car is out of service for 15 or more cumulative days due to repairs, it also qualifies.
For serious safety defects, the standard is stricter. If the issue could cause injury or death and isn’t fixed after 1 repair attempt, you may already have a valid claim.
Vehicles Covered vs. Not Covered
The Massachusetts Lemon Law applies to:
- New cars, trucks, and motorcycles purchased or leased in Massachusetts
- Vehicles still under the manufacturer’s original warranty
- Demonstrator or executive vehicles (if sold as new)
It does not cover:
- Used vehicles (unless they’re still under the original warranty)
- Vehicles purchased out of state (unless registered in MA)
- Defects caused by abuse, neglect, or unauthorized modifications
- Issues from normal wear and tear
Your Step-by-Step Guide to Filing a Lemon Law Claim

Start by gathering all repair orders and invoices. Each document should show the date, the defect described, and the work performed. Without this paper trail, your claim will be much harder to prove.
Next, notify the manufacturer in writing via certified mail. This creates a record that you’ve formally requested a resolution.
Documenting Repairs the Right Way
Every time your car goes in for repairs, ask for a detailed work order. Note the mileage at drop-off and pick-up. If the dealer won’t provide one, write down the service advisor’s name and the date yourself.
Take photos or videos of the issue if it’s visible. A picture of a check engine light or a malfunctioning feature can strengthen your case.
Notifying the Manufacturer
Your written notice should include your name, address, and vehicle details. List the defect, the repair attempts, and the dates. State clearly that you’re invoking your rights under the Massachusetts Lemon Law.
Send it to the manufacturer’s customer service address, not the dealership. You can find this in your owner’s manual or on their official website.
Requesting Arbitration Through the AG’s Office
If the manufacturer doesn’t resolve the issue, file for arbitration with the Massachusetts Attorney General’s Office. The process is free and typically takes 45 to 60 days.
You’ll need to submit your repair documents and a completed claim form. The AG’s office will then schedule a hearing where both sides can present their case.
What Happens After You File?
Once your claim is submitted, the manufacturer has a chance to respond. They may offer a final repair attempt, a replacement vehicle, or a refund. If they dispute the claim, the arbitration process will proceed.
The arbitrator will review the evidence and issue a binding decision. If you win, the manufacturer must comply within 30 days. If you lose, you can still pursue legal action in court.
Manufacturer’s Options: Repair, Replace, or Refund

The manufacturer can choose to make one last repair attempt. If successful, the case is closed. If not, you can reopen your claim.
A replacement vehicle must be of equal value to your original car. It should have similar features and mileage. You won’t pay extra for the swap.
For a refund, you’ll get the full purchase price back. This includes taxes, fees, and finance charges. The manufacturer may deduct a reasonable allowance for mileage.
How the Refund or Replacement Is Calculated
The refund is based on the original purchase price minus a mileage offset. The offset is calculated using a formula set by state law. It accounts for the time you’ve used the vehicle before the defect became apparent.
For replacements, the manufacturer covers the cost of a comparable new vehicle. You won’t be responsible for any additional fees or charges.
Common Mistakes That Sink Lemon Law Claims
Waiting too long to act is a big mistake. You must file within 18 months of the vehicle’s delivery date. After that, you lose your eligibility.
Another error is skipping the written notice to the manufacturer. Verbal complaints aren’t enough. You need a paper trail to prove you gave them a chance to fix the issue.
Finally, don’t sign anything from the manufacturer without reviewing it carefully. Some agreements may waive your rights under the Lemon Law. Always consult a legal expert if you’re unsure.
When to Hire a Lemon Law Attorney in Massachusetts
You don’t need a lawyer to file a Lemon Law claim, but one can help if the manufacturer pushes back. Attorneys specializing in this area often work on contingency, meaning they only get paid if you win.
If your case involves complex defects or the manufacturer is uncooperative, legal representation can level the playing field. The law also allows you to recover attorney’s fees if you prevail in court.
Massachusetts Lemon Law vs. Federal Lemon Law
The federal Magnuson-Moss Warranty Act offers some protections, but it’s less consumer-friendly than Massachusetts’ law. The federal version doesn’t have the same clear thresholds for repair attempts or days out of service.
Massachusetts’ law is stricter and more specific. It also covers a broader range of vehicles and provides a clearer path to resolution through state arbitration.
Real-World Example: A Successful MA Lemon Law Case
A Boston driver purchased a new SUV that kept stalling. After 4 repair attempts and 20 days in the shop, the issue persisted. The owner filed a claim with the AG’s office.
The arbitrator ruled in the consumer’s favor. The manufacturer was ordered to buy back the vehicle and reimburse all related costs, including taxes and fees.
FAQs About Massachusetts Lemon Law
Does the Lemon Law cover leased vehicles?
Yes. Leased vehicles are treated the same as purchased ones under Massachusetts Lemon Law. The same thresholds for repair attempts and days out of service apply.
What if the dealer says the problem is “normal”?
If the defect substantially impairs the vehicle’s use, value, or safety, it doesn’t matter if the dealer considers it normal. Document the issue and continue pursuing repairs under warranty.
How long does the arbitration process take?
The Massachusetts Attorney General’s Office typically resolves Lemon Law arbitration cases within 45 to 60 days. Complex cases may take longer, but the process is designed to be efficient.
Can I still file if I’ve modified my car?
Modifications can complicate your claim. If the defect is unrelated to the modifications, you may still qualify. However, unauthorized changes can void your warranty, so proceed carefully.
