Yes, New Hampshire has a comprehensive and consumer-friendly Lemon Law codified under New Hampshire Revised Statutes Annotated (RSA) Chapter 357-D. Known officially as the Motor Vehicle Warranty Law, it provides that if a new motor vehicle cannot be repaired after a reasonable number of attempts, the manufacturer must provide a full purchase refund or a comparable new replacement vehicle.
Statutory Framework: New Hampshire RSA Chapter 357-D
Purchasing or leasing a brand-new automobile is one of the largest financial investments a consumer makes. When a newly purchased vehicle exhibits persistent, severe mechanical defects?”such as transmission failures, electronic engine stalling, malfunctioning braking systems, or recurrent electrical blackouts?”consumers are protected under New Hampshire state law. Under New Hampshire RSA Chapter 357-D, consumers are safeguarded against defective motor vehicles that fail to conform to manufacturer express warranties.
The New Hampshire Lemon Law applies to any new passenger motor vehicle, motorcycle, or truck with a gross vehicle weight rating under 9,000 pounds sold or leased in the State of New Hampshire. The law covers nonconformities?”defined as any defect, malfunction, or condition that substantially impairs the vehicle use, market value, or physical safety. The statutory coverage window extends throughout the manufacturer express warranty term, or within one year from the original vehicle delivery date, whichever occurs first.
A distinctive feature of New Hampshire Lemon Law is its state-administered dispute resolution mechanism: the New Hampshire Motor Vehicle Arbitration Board. Operated directly under the New Hampshire Department of Justice (Office of the Attorney General), this specialized administrative board provides consumers with a fast, binding, and low-cost alternative to expensive, drawn-out civil court litigation. The comparative table below outlines statutory qualifications, vehicle coverage, and legal remedies under RSA 357-D.
| Statutory Parameter | New Hampshire Lemon Law (RSA 357-D) | Consumer Advantage |
|---|---|---|
| Covered Vehicles | New passenger cars, light trucks (under 9,000 lbs), motorcycles | Broad coverage across everyday consumer vehicles |
| Coverage Window | Express warranty period or 1 year from delivery date | Protects consumer throughout early ownership lifecycle |
| Repair Attempt Presumption | 3 repair attempts for the same recurring defect | Clear, objective legal threshold proving “reasonable attempts” |
| Cumulative Out-of-Service Time | 30 or more cumulative business days out of service | Protects against chronic shop delays and backordered parts |
| Primary Legal Remedies | 100% Full purchase price refund or comparable new vehicle | Complete financial restitution including taxes and fees |
The Legal Presumption: 3 Attempts or 30 Business Days
To establish that a vehicle is legally a “lemon,” the consumer must prove that the manufacturer or its authorized franchised dealership has been afforded a “reasonable number of repair attempts” to correct the defect. Under RSA 357-D:3, New Hampshire law creates an unassailable legal presumption that a reasonable number of attempts have occurred if the vehicle meets either of two statutory benchmarks.
The first benchmark is the Three-Repair-Attempt Rule. If the same substantial nonconformity has been subjected to repair three or more times by an authorized dealer within the warranty period, and the defect continues to persist or recurs, the vehicle qualifies as a lemon. The second independent benchmark is the Thirty-Business-Day Rule. If the vehicle is out of service by reason of repair for a cumulative total of 30 or more business days (excluding Sundays and legal holidays) within the warranty period, the consumer is entitled to statutory relief, regardless of whether the downtime was for a single major defect or multiple unrelated mechanical problems. The table below details these statutory triggers.
| Statutory Trigger | Legal Benchmark Criteria | Manufacturer Defense Allowed | Consumer Outcome |
|---|---|---|---|
| 3-Repair-Attempt Presumption | 3 failed repair visits for the exact same defect | Must prove defect does not impair use, value, or safety | Manufacturer must replace or refund vehicle |
| 30-Business-Day Presumption | 30 cumulative business days in repair shop | Must prove delay caused by war, strike, or natural disaster | Manufacturer must replace or refund vehicle |
| Final Opportunity to Repair | Mandatory written notice sent to manufacturer HQ | Manufacturer gets 7 business days for final repair attempt | If uncorrected after 7 days, consumer files for arbitration |
| Abuse / Neglect Defense | Manufacturer alleges owner modified or abused car | Manufacturer bears burden of proving customer abuse | Defect must stem from factory workmanship or parts |
The New Hampshire Motor Vehicle Arbitration Board Process
Unlike many states that force consumers into manufacturer-sponsored private arbitration programs (such as the Better Business Bureau Auto Line) with inherent corporate biases, New Hampshire provides an impartial state board: the New Hampshire Motor Vehicle Arbitration Board. Consisting of citizen consumers and independent automotive technical experts appointed by the Governor, the board meets monthly in Concord to conduct administrative hearings.
Filing for state arbitration requires paying a nominal $50 administrative fee. Once a complete application is submitted with copies of dealership work orders and repair invoices, the Board schedules a formal hearing within 40 days. At the hearing, the consumer presents repair orders, and the Board technical experts physically inspect and test-drive the vehicle. The Board renders a final, legally binding written decision within 14 days of the hearing. If the Board rules in the consumer favor, the manufacturer must issue a full refund?”including the purchase price, finance charges, registration fees, and state sales/excise taxes, minus a modest statutory mileage deduction for pre-defect driving?”within 30 days.
