What Qualifies as a Lemon in New Mexico?
A vehicle is considered a lemon if it has a defect that substantially impairs its use, value, or safety. This includes issues like persistent engine failures, electrical problems, or safety-related defects like faulty brakes or airbags.
The defect must occur within the first year of ownership or the first 12,000 miles, whichever comes first. Minor problems like a broken radio or cosmetic flaws typically don’t meet the threshold.

Who Is Protected Under NM's Lemon Law?
The New Mexico Motor Vehicle Quality Assurance Act protects consumers who purchase or lease new vehicles in the state. This includes cars, trucks, motorcycles, and demonstrator vehicles.
Protection extends to the original owner or lessee, as well as anyone who receives the vehicle as a gift or through inheritance. Businesses that purchase vehicles for commercial use are generally not protected.
Step-by-Step: How to File a Lemon Law Claim
Filing a lemon law claim in New Mexico requires careful documentation. Here’s how to do it:
Document all repairs: Keep copies of every repair order, invoice, and communication with the dealer or manufacturer.
Notify the manufacturer: Send a written notice via certified mail detailing the defect and repair attempts.
Allow a final repair attempt: The manufacturer may request one last chance to fix the issue.
File a complaint: If the issue persists, file with the New Mexico Attorney General’s Office.
Arbitration or lawsuit: If arbitration fails, you may pursue legal action. Under New Mexico law, the manufacturer must cover your attorney fees if you win.

Missing the Deadline
The 1-year or 12,000-mile window is strict. File your complaint as soon as you recognize the problem.
Failing to Document Repairs
Without proper records, you cannot prove the number of repair attempts or days in the shop.
Not Notifying the Manufacturer in Writing
You must give written notice before taking legal action. Send it via certified mail.
Accepting a Buyout Too Quickly
Do not sign any agreement until you understand your full rights. You may be entitled to a full refund or replacement.
Signing Away Your Rights
New Mexico law prohibits waiving lemon law protections. If you see such a clause, consult an attorney.
