The South Dakota Lemon Law (SDCL § 32-6D)
South Dakota's lemon law in detail — the two-tier rights/presumption window, the 4-attempt / 30-calendar-day presumption, certified-mail notice, the consumer-elected remedy, the 100,000-mile offset, and the manufacturer-IDS prerequisite.
South Dakota’s lemon law is codified at SDCL § 32-6D-1 to § 32-6D-11. It is consumer-favorable in several respects — the consumer elects refund or replacement, the use offset uses a 100,000-mile basis, and the lemon law provides its own attorney fees — but it has a distinctive two-tier timing structure and a certified-mail notice requirement that trap the unwary.
The core promise
Section 32-6D-3 requires the manufacturer, when it cannot conform the vehicle to the warranty after a reasonable number of attempts, to — at the option of the consumer — replace the vehicle or refund the purchase price. The consumer chooses (consumer-election, like New Hampshire, Rhode Island, and Delaware).
Who’s covered
Section 32-6D-1(5) covers a self-propelled vehicle intended primarily for use on the public highways, for personal use.
Excluded / not addressed:
- Motor homes — excluded.
- Vehicles of 15,000 lbs GVWR or more — excluded.
- Leases — not addressed in the statute (lessees should look to Magnuson-Moss).
- Motorcycles — not expressly excluded, so a highway motorcycle may qualify (confirm coverage).
The two-tier window — report early, build later
This is South Dakota’s signature feature:
- Lemon law rights period (§ 32-6D-1): the nonconformity must first be reported within one year or 12,000 miles, whichever is earlier.
- Presumption window (§ 32-6D-5): the threshold (4 attempts + final attempt, or 30 calendar days) must be met within two years or 24,000 miles, with at least one repair attempt during the rights period.
So the defect must surface early (1 year / 12,000 miles), but you have a longer window (2 years / 24,000 miles) to accumulate the repair attempts. See statute of limitations.
The presumption: 4 attempts (+ a final attempt) or 30 calendar days
Section 32-6D-5 presumes a reasonable number of attempts where, within 2 years / 24,000 miles (with at least one attempt during the rights period):
- The same nonconformity has been subject to repair 4 or more times and a final repair attempt, and it persists; OR
- The vehicle has been out of service a cumulative 30 or more calendar days (including the final repair attempt).
South Dakota has no one-attempt rule. See repair-attempt presumption.
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 opportunity. Keep proof of the certified mailing.
The refund and the 100,000-mile offset
The refund returns the full contract price (including undercoating, dealer-prep, transportation, and installed options), the nonrefundable portions of extended warranties/service contracts, collateral charges (excise tax, license, registration, and similar government charges), and finance charges incurred after the first report — plus incidental damages including reasonable alternative-transportation costs.
The use offset (§ 32-6D) is the full purchase price multiplied by a fraction:
- Numerator — miles driven before the first report of the nonconformity.
- Denominator — 100,000.
The 100,000-mile denominator and before-first-report numerator keep the deduction small.
Attorney fees and the manufacturer-IDS prerequisite
Section 32-6D-8 lets the consumer recover reasonable attorney fees if the manufacturer breaches its obligations. And under § 32-6D-6, a manufacturer’s federally compliant informal dispute settlement (IDS) program is a prerequisite to a civil action. See manufacturer arbitration and attorney fees.
How South Dakota compares
| Feature | South Dakota | Delaware | Montana | North Dakota |
|---|---|---|---|---|
| Enforcement | Manufacturer IDS then court | Certified IDS then court | DOJ arb / IDS (in MT) | (see ND guide) |
| Same-defect attempts | 4 (+ final) | 4 | 4 | — |
| Safety-defect attempts | None | None | None | — |
| OOS threshold | 30 calendar days | 30 calendar days | 30 business days | — |
| Window | Report 1 yr/12K; presume 2 yr/24K | Warranty / 1 yr (no mileage) | 2 yr / 18,000 mi | — |
| Remedy election | Consumer | Consumer | Manufacturer | — |
| Use offset | ÷100,000-mi (pre-report) | ÷100,000-mi | ÷100,000-mi | — |
| Lemon-law fees | Yes (§ 32-6D-8) | Discretionary | None (via CPA) | — |
| UDAP treble | None (weak DTPA) | Mandatory | Discretionary | — |
South Dakota stands out for its two-tier window, the certified-mail notice + 7/14-day cure, its own attorney-fee provision, and a weak DTPA (no treble).
Bottom line
The South Dakota Lemon Law gives consumers a consumer-elected refund or replacement, a small 100,000-mile offset, and its own attorney fees — but the two-tier window (report within 1 year/12,000 miles) and certified-mail notice are easy to miss. Exhaust any manufacturer IDS, then sue within 3 years (§ 32-6D-11), pairing Magnuson-Moss.
