To file a lemon law claim in New Hampshire, document every repair attempt on your defective vehicle, notify the manufacturer in writing after repeated unsuccessful repairs or extended downtime, provide the manufacturer with a final opportunity to repair the defect, and then pursue relief through the manufacturer's dispute settlement program or the New Hampshire New Motor Vehicle Arbitration Board. New Hampshire's lemon law, found in RSA 357-D, protects buyers and qualifying lessees of new motor vehicles that cannot be repaired during the manufacturer's express warranty period. If your vehicle qualifies, you may be entitled to a refund, replacement vehicle, or manufacturer buyback.

This guide explains how New Hampshire's lemon law works, whether your vehicle qualifies, the steps to file a claim, and the remedies available if the manufacturer cannot repair your vehicle.
What Is New Hampshire Lemon Law?
The Federal Highway Administration data show that approximately 1.44 million motor vehicles were registered in New Hampshire in 2024, underscoring how important dependable transportation is for residents throughout the state. New Hampshire's Lemon Law is codified in RSA Chapter 357-D and establishes the New Motor Vehicle Arbitration Program. The law requires manufacturers to honor their warranties when a substantial defect cannot be repaired within a reasonable number of attempts.
A vehicle becomes a lemon when it develops a defect covered by the manufacturer's express warranty that substantially impairs its use, market value, or safety, and the manufacturer or its authorized dealer cannot successfully repair it after being given a reasonable opportunity. Minor cosmetic issues generally do not qualify. Instead, the defect must meaningfully affect the vehicle's operation, value, or safety. Problems involving the engine, transmission, steering, braking system, electrical components, or other critical systems often meet this standard.
During the manufacturer's express warranty period, manufacturers must repair covered defects at no cost to the owner. When those repairs repeatedly fail, New Hampshire law provides consumers with the right to seek a replacement vehicle or refund through arbitration or other legal remedies.
Does Your Vehicle Qualify Under New Hampshire Lemon Law?
New Hampshire's Lemon Law generally applies to new motor vehicles sold or leased in the state, including passenger cars, pickup trucks that meet the statutory weight limit, motorcycles, and certain off-highway recreational vehicles covered by a manufacturer's express warranty. Leased vehicles may also qualify if the initial lease term is at least two years.
To qualify, the defect must be covered by the manufacturer's warranty and substantially impair the vehicle's use, value, or safety. Common examples include persistent transmission problems, engine stalling, electrical system failures, brake defects, steering issues, and recurring warning lights caused by serious mechanical failures. Damage resulting from abuse, neglect, accidents, unauthorized modifications, or improper maintenance is generally not covered.
Unlike some states that limit coverage to a specific mileage or one-year period, New Hampshire's Lemon Law generally applies throughout the manufacturer's express warranty period. As a result, the terms and duration of the warranty play an important role in determining whether a vehicle qualifies for protection.
New Hampshire Lemon Law Eligibility Requirements
New Hampshire establishes a presumption that the manufacturer has received a reasonable opportunity to repair when certain conditions are met.
Generally, the presumption applies if:
- ## The manufacturer or authorized dealer has attempted to repair the same defect at least three times, and the defect continues to exist; or
- ## The vehicle has been out of service because of warranty repairs for 30 or more business days during the warranty period.
Before pursuing a refund or replacement, the consumer must provide the manufacturer with written notice requesting relief and allowing one final opportunity to repair the vehicle. Under New Hampshire law, the manufacturer generally has 40 days after receiving written notice to correct the defect before the consumer may proceed with arbitration.
Consumers also must continue making required vehicle payments while the claim is pending, and each repair visit should be documented with written repair orders obtained from the dealership.
Maintaining complete documentation throughout the repair process significantly strengthens a lemon law claim.
How to File a Lemon Law Claim in New Hampshire
Filing a lemon law claim is a process where each step strengthens your case. Following the right sequence can help demonstrate that the manufacturer had a fair opportunity to repair the defect but failed to do so.
Step 1. Determine qualification: Confirm your vehicle is covered under New Hampshire's lemon law, the defect substantially impairs its use, value, or safety, and the problem arose during the manufacturer's warranty period.
Step 2. Gather records: Collect your purchase or lease agreement, vehicle registration, title, warranty booklet, and any documents showing the terms of your warranty coverage.
Step 3. Document repair attempts and downtime: Keep every repair order, service invoice, and record showing how long the vehicle remained at the dealership for warranty repairs.
Step 4. Create a defect timeline: Prepare a chronological summary identifying when the defect first appeared, each repair visit, the work performed, and whether the problem returned after each repair.
Step 5. Notify the manufacturer: Send written notice explaining the continuing defect and your request for relief directly to the manufacturer, rather than relying solely on communications with the dealership.
Step 6. Allow a final repair opportunity: If required under New Hampshire law, provide the manufacturer with one final opportunity to repair the vehicle before pursuing statutory remedies.
Step 7. Organize documentation: Assemble your repair records, correspondence, warranty documents, and defect timeline into a complete claim package that clearly supports your position.
Step 8. Submit your claim: File your New Hampshire lemon law claim through any applicable dispute resolution process or pursue the appropriate legal remedy available under state law.
Step 9. Pursue a refund, replacement, or buyback: Present your documentation and seek the remedy that best applies to your circumstances, whether that is a manufacturer buyback, replacement vehicle, settlement, or other available relief.
New Hampshire Lemon Law Documents Checklist
The strength of a New Hampshire lemon law claim often depends on the documents you can provide. Before beginning the claims process, gather the following records to establish your vehicle's warranty coverage, repair history, and communications with the manufacturer.
- ### Purchase or lease agreement: Confirms when the vehicle was acquired and the terms of the purchase or lease.
- ### Vehicle registration and title: Establishes ownership and identifies the vehicle involved in the claim.
- ### Warranty booklet and warranty documents: Explains the manufacturer's warranty coverage and repair obligations.
- ### Repair orders from every service visit: Records each repair attempt and the defect reported to the dealership.
- ### Repair invoices: Shows the repairs completed, replacement parts installed, and dates of service.
- ### Service and maintenance records: Demonstrates that the vehicle has been properly maintained throughout ownership.
- ### Complete repair history: Helps establish that the same defect continued despite multiple repair attempts.
- ### Written communications with the manufacturer: Preserves notices, emails, letters, and responses relating to the defect.
- ### Communications with the dealer: Documents conversations, appointments, and recommendations provided during the repair process.
- ### Vehicle downtime records: Shows how long the vehicle remained unavailable because of warranty repairs, including rental or loaner vehicle documentation if available.
- ### Claim documents: Keeps copies of dispute resolution filings, settlement offers, manufacturer responses, and any other documents related to your claim.
What Are New Hampshire's Manufacturer Notice Requirements?
Written notice is one of the most important steps in a New Hampshire lemon law claim because it gives the manufacturer a final opportunity to repair the vehicle before arbitration or litigation begins.
Once repeated repairs have failed, send written notice directly to the manufacturer. Do not rely solely on conversations with the dealership, as the dealer and manufacturer are separate entities under the law.
Your notice should identify the vehicle, explain the defect, summarize the repair history, and clearly state that you are seeking relief under New Hampshire's Lemon Law. Include copies of repair orders whenever possible.
Send the notice using a method that provides proof of delivery, such as certified mail with return receipt requested. As Aaron Waldo, an attorney at RockPoint Law, often advises clients, "If you can't prove the manufacturer received your notice, you may end up arguing about the mailing instead of the defect."
After receiving written notice, the manufacturer generally has one final opportunity, up to 40 days, to repair the vehicle. If the defect remains unresolved after that period, you may proceed with arbitration or pursue other remedies available under New Hampshire law.
What Remedies Are Available Under New Hampshire Lemon Law?
When a vehicle qualifies under New Hampshire's Lemon Law, the manufacturer is generally required to provide a remedy. In most cases, this means either replacing the defective vehicle with a comparable new vehicle or repurchasing it through a manufacturer buyback. The appropriate remedy depends on the circumstances of the claim and the consumer's election where permitted by law.
If you choose a refund, the manufacturer generally must reimburse the purchase price of the vehicle, subject to a reasonable allowance for your use of the vehicle before the defect was first reported. Depending on the claim, the refund may also include recoverable collateral charges such as sales tax, registration and title fees, finance charges, dealer-installed options, and other expenses allowed under New Hampshire law.
If you would rather keep driving the same make or model, you may instead choose a comparable replacement vehicle with substantially similar features and warranty coverage. A replacement can be a practical option when an equivalent vehicle is readily available and better suits your needs than a refund.
Depending on the facts of your case, you may also be entitled to recover reasonable attorney's fees where authorized by law, incidental damages related to the defect, and other remedies available under state or federal consumer protection laws. Whether a refund or replacement is the better option often depends on your financial situation, the availability of comparable vehicles, and your long-term transportation needs.
What Are the Common Mistakes That Can Hurt a New Hampshire Lemon Law Claim?
Many otherwise valid lemon law claims become more difficult because consumers make avoidable mistakes during the repair process. Waiting too long to act is one of the most common issues. Repeated repairs without documenting the recurring defect can make it harder to prove the manufacturer had a reasonable opportunity to fix the problem during the warranty period.
Poor documentation can also weaken a claim. Every repair visit should result in a written repair order and final invoice, as these records help establish the history of the defect. In addition, consumers should notify the manufacturer in writing rather than relying solely on conversations with the dealership, since written notice is often required before certain remedies become available.
Another common mistake is accepting the manufacturer's first settlement offer without understanding the full value of the claim. Consumers should also organize repair records, correspondence, and a clear timeline before beginning arbitration or other proceedings. Well-prepared documentation can significantly strengthen a lemon law claim and improve the likelihood of a successful outcome.
New Hampshire Lemon Law Examples
The following examples are for illustrative purposes only. They do not describe actual RockPoint Law clients and should not be interpreted as guarantees of future results.
Consider a driver in Manchester whose new SUV develops recurring electrical failures that cause the dashboard to shut down and safety systems to malfunction. The dealership attempts repairs three separate times during the manufacturer's warranty period, but the problem continues. After providing written notice to the manufacturer and allowing a final repair opportunity, the driver may qualify for a refund or replacement under New Hampshire's Lemon Law.
Now consider a family in Nashua whose new pickup truck spends more than 30 business days in the repair shop because of repeated transmission failures covered by the manufacturer's warranty. Although the dealer performs multiple repairs, the truck remains unreliable. Because the vehicle has been out of service for an extended period, the owner may satisfy the statutory presumption for relief.
These examples illustrate an important point: consumers who keep complete records, act promptly, and follow the statutory process generally place themselves in the strongest position to pursue a successful claim.
