When Is a Car a Lemon in New Mexico?
New Mexico's Motor Vehicle Quality Assurance Act thresholds — 4 same-defect repairs or 30 cumulative business days out of service, within the warranty term or one year.
A vehicle qualifies as a “lemon” under New Mexico’s Motor Vehicle Quality Assurance Act when the manufacturer has had a reasonable number of attempts to repair a substantial defect and failed.
The thresholds
| Test | Threshold |
|---|---|
| Same uncorrected nonconformity, repair attempts | 4 or more |
| Cumulative business days out of service | 30 or more (≈42 calendar days) |
PLUS:
- Defect substantially impairs use and market value.
- Within the warranty term or one year from delivery, whichever earlier.
- A final repair opportunity given to the manufacturer.
What counts as a “repair attempt”
- Vehicle was at an authorized dealer, with a repair order.
- You reported the defect (even “no problem found” visits count).
- The same uncorrected nonconformity persists.
- Independent-mechanic visits and routine maintenance don’t count.
Business days, not calendar days
New Mexico counts business days for the out-of-service test — about six calendar weeks for 30 business days. Track in/out dates precisely; see documenting evidence.
No separate safety-defect threshold
Unlike Virginia or Georgia, New Mexico applies the same 4-attempt / 30-business-day rule to all defects. But a single dangerous defect can still support a UPA or Magnuson-Moss claim.
Bottom line
If you’ve had four same-defect repairs or 30+ cumulative business days out of service — within the warranty term or one year — you likely qualify. Watch the 18-month SOL. Get a free case review to confirm.
