South Dakota's Repair-Attempt Presumption (4 Attempts / 30 Calendar Days)
How South Dakota presumes a reasonable number of attempts — 4 same-defect repairs plus a final attempt, or 30 cumulative calendar days — within the two-tier window, plus the certified-mail notice.
South Dakota presumes a “reasonable number of attempts” under SDCL § 32-6D-5 when one of two thresholds is met — within a distinctive two-tier window, and after certified-mail notice with a final cure.
The two-tier window
- Rights period (§ 32-6D-1): the nonconformity must first be reported within one year or 12,000 miles, whichever earlier.
- Presumption window (§ 32-6D-5): the threshold must be reached within two years or 24,000 miles, with at least one repair attempt during the rights period.
So the defect must surface early, but the attempts can accumulate over a longer window.
The two thresholds
| Test | Threshold |
|---|---|
| Same nonconformity, repair attempts | 4 or more, plus a final repair attempt (and it persists) |
| Cumulative calendar days out of service | 30 or more (including the final repair attempt) |
No one-attempt safety rule
Unlike Maine and Idaho (one attempt for a serious braking/steering failure) or Hawaii (one attempt for any serious safety defect), South Dakota has no reduced threshold for serious defects — every defect must reach 4 attempts (plus a final attempt) or 30 calendar days. A safety defect still strengthens the overall case.
Certified-mail notice and the final cure
The consumer must give notice of the nonconformity by certified mail to the manufacturer (§ 32-6D-6). The manufacturer then has 7 days to identify a repair facility and 14 calendar days to correct the nonconformity — the final repair attempt that the presumption requires. Keep proof of the certified mailing and the final-cure result.
The 12,000-mile reporting window
Because the report must occur within 1 year or 12,000 miles, and South Dakota’s rural drivers cover long distances, watch the odometer — a high-mileage commuter can pass 12,000 miles quickly. Report the defect early; the attempts can then accumulate to 2 years / 24,000 miles.
What counts as a repair attempt
- Vehicle was at the manufacturer or an authorized dealer, documented by a repair order.
- The same nonconformity persists.
- “No problem found” visits count if the defect was reported.
- Independent-mechanic visits and routine maintenance don’t count.
Bottom line
Four same-defect repairs plus a final attempt, or 30 cumulative calendar days out of service — within the two-tier window (report by 1 year / 12,000 miles; presume by 2 years / 24,000 miles), after certified-mail notice — raises South Dakota’s presumption. There’s no one-attempt safety shortcut, so report early and document carefully.
