Documenting Evidence for a New Mexico Lemon Law Claim
What to keep for a New Mexico Motor Vehicle Quality Assurance Act claim — repair orders, the business-day out-of-service count, written notice, and UPA misrepresentation evidence.
Documentation wins New Mexico lemon-law cases. Because the Motor Vehicle Quality Assurance Act turns on a 4-attempt or 30-business-day presumption inside a tight one-year window, contemporaneous records are the difference between a clean presumption and a contested one.
The core record: repair orders
For every dealer visit, keep the repair order showing:
- Date in and date out — critical for the business-day out-of-service count.
- Your description of the defect — in your own words, consistent across visits.
- The technician’s diagnosis and work performed (or “no problem found”).
- Mileage at each visit.
- Parts replaced.
Request a printed copy at every visit, even quick ones. “No problem found” visits still count if you reported the defect.
Track the same-nonconformity count
The presumption requires four attempts on the same uncorrected nonconformity. Keep a simple log:
| Visit | Date in | Date out | Business days OOS | Defect reported | Outcome |
|---|
Consistent defect descriptions keep the same-defect chain intact. If a dealer mislabels the complaint, correct it in writing.
Count business days carefully
New Mexico counts business days, not calendar days, for the 30-day out-of-service threshold. Exclude weekends and exclude downtime for routine maintenance. Thirty business days is roughly six calendar weeks — keep your in/out dates precise so the cumulative count is defensible.
Preserve written notice
Keep a copy of any written notice to the manufacturer and proof of delivery (certified-mail receipt). This supports the final-repair-opportunity step and the 18-month SOL timeline.
Evidence for a UPA willful finding
For the UPA treble-damages and mandatory-fee theory, preserve anything showing the manufacturer knew of the defect:
- Technical Service Bulletins (TSBs) matching your defect.
- Recall notices for the same component.
- Customer-relations call logs and email.
- Marketing or sales representations about reliability, range, or features.
- Patterns of denial or delay.
Photo and video evidence
- Video the defect when it occurs (dash warnings, stalling, infotainment crashes).
- Photograph dashboards, leaks, and damage.
- Date-stamp everything.
Build the financial record
- Purchase/lease contract — establishes price and collateral charges (tax, title, license, registration) for the refund.
- Rental and towing receipts — recoverable as incidental/UPA damages.
- Out-of-pocket repair receipts.
Bottom line
In New Mexico, the presumption lives or dies on repair orders and an accurate business-day out-of-service count, captured inside the one-year Rights Period. Layer in TSBs and manufacturer-knowledge evidence to unlock the UPA’s treble damages and mandatory fees.
