Lemon Law in New Mexico
How many repair attempts and days out of service before New Mexico presumes your vehicle is a lemon, and whether used cars are covered.
presumption trigger (same defect)
Do I meet the New Mexico lemon presumption?
Enter your repairs and downtime. This checks the presumption; it is not a legal verdict.
This checklist is educational, not a legal verdict. Every state writes these numbers as a rebuttable presumption: hitting them shifts the burden to the manufacturer, and the manufacturer can still rebut it. Keep every repair order, send any required written notice, and consult a lawyer about your specific facts. This is legal information, not legal advice.
How the presumption works in New Mexico
The prongs that shift the burden to the manufacturer.
The 30-day out-of-service count excludes downtime for routine maintenance prescribed by the manufacturer. The consumer must give the manufacturer prior direct written notice of the defect before the presumption can be used.
Every state, New Mexico included, writes these thresholds as a rebuttable presumption. Reaching them shifts the burden onto the manufacturer to prove your vehicle is not a lemon; it does not mean you automatically win. You may also qualify with fewer attempts if a "reasonable number" of repairs is shown some other way, and the manufacturer can rebut the presumption. This is legal information, not legal advice.

What New Mexico car buyers get wrong
New Mexico’s lemon law is the Motor Vehicle Quality Assurance Act, and it hinges on a step many owners miss: written notice to the manufacturer. Under NMSA §57-16A-3(C) the state presumes a lemon after 4 or more repair attempts on the same nonconformity, or 30 or more business days out of service, within the earlier of the warranty term or 1 year from delivery. But the presumption does not apply against a manufacturer unless that manufacturer first got prior direct written notice and a chance to cure the defect, so keep a paper trail and send that notice. The 30-day count leaves out downtime for routine maintenance the manufacturer prescribes. If the manufacturer runs a certified arbitration program, you generally have to go through it before seeking a refund or replacement. As always, clearing the numbers is a presumption that shifts the burden to the manufacturer, not an automatic win, and New Mexico covers new vehicles only.
Common questions
How many repair attempts is a lemon in New Mexico?
New Mexico presumes a lemon after 4 or more attempts on the same nonconformity, or 30 or more business days out of service, within the earlier of the warranty term or 1 year from delivery. That shifts the burden to the manufacturer rather than deciding the case outright.
Do I have to notify the manufacturer before making a lemon claim in New Mexico?
Yes. The presumption does not apply against a manufacturer unless it first received prior direct written notice of the defect and an opportunity to cure it. Sending written notice and keeping a copy is important.
Does the New Mexico lemon law cover used cars?
No. The Motor Vehicle Quality Assurance Act covers new motor vehicles. New Mexico has no separate used-car lemon law, so used vehicles fall outside the Act.
Do I have to arbitrate before suing in New Mexico?
Often, yes. If the manufacturer has a certified informal dispute-settlement (arbitration) program, you generally must use it before pursuing the Act’s refund or replacement remedy.
