The Law: South Dakota Lemon Law and the Deceptive Trade Practices Act

South Dakota’s lemon law — SDCL § 32-6D-1 to § 32-6D-11 — delivers a refund or replacement through a structured process anchored by certified-mail notice and a manufacturer-IDS prerequisite. Because the state’s Deceptive Trade Practices statute is comparatively weak, the lemon law’s own fee provision and federal Magnuson-Moss carry the leverage.

The three pillars

1. South Dakota Lemon Law — SDCL § 32-6D-1 to -11. A 4-attempt (+ final attempt) / 30-calendar-day presumption; a distinctive two-tier window (report within 1 year / 12,000 miles, presumption within 2 years / 24,000 miles); a consumer-elected refund or replacement; certified-mail notice with a 7-day/14-day final cure; and a manufacturer-IDS prerequisite (§ 32-6D-6).
2. South Dakota Deceptive Trade Practices and Consumer Protection — SDCL ch. 37-24, private action under § 37-24-31 for actual damages only. There is no treble, no statutory minimum, no general attorney-fee provision (§ 37-24-48’s fee award is for unsolicited-commercial-email claims, not the general consumer action), a heightened intent requirement, and no per se lemon-law link. A comparatively weak UDAP — fees come from the lemon law (§ 32-6D-8) and Magnuson-Moss.
3. Federal Magnuson-Moss Warranty Act — 15 U.S.C. § 2301 et seq. Civil court; § 2310(d)(2) attorney fees; federal-court access (D.S.D.).

South Dakota pairs a consumer-favorable lemon law (with its own fees) with a limited UDAP — so the lemon law and Magnuson-Moss matter most.

Topics in this section

• South Dakota Lemon Law statute (§ 32-6D) — Eligibility, the two-tier window, the presumption, the consumer-elected remedy, and the 100,000-mile offset.
• South Dakota Deceptive Trade Practices (SDCL 37-24) — Actual damages only (§ 37-24-31), no treble, and the limits.
• Magnuson-Moss Warranty Act — Federal overlay and fee hook.
• Repair-attempt presumption — The 4-attempt and 30-calendar-day thresholds, the final cure, and the certified-mail notice.
• Statute of limitations — The two-tier window and the 3-year filing deadline.

Why three statutes instead of one

The Lemon Law delivers refund or replacement and provides attorney fees (§ 32-6D-8). The Deceptive Trade Practices statute adds:

• Actual damages for a deceptive practice (§ 37-24-31).
• But no treble, no general fee provision, and no per se lemon-law link — so fees come from the lemon law and Magnuson-Moss.

Magnuson-Moss adds federal-court access (D.S.D.), § 2310(d)(2) fees, and a 4-year runway.

How they interact procedurally

1. Report the defect within the rights period (1 year / 12,000 miles) and give certified-mail notice (§ 32-6D-6).
2. Allow the final cure — 7 days to identify a facility, 14 calendar days to repair.
3. Exhaust any manufacturer IDS (§ 32-6D-6), then file a civil action — within 3 years of delivery (§ 32-6D-11), pairing the lemon law with Magnuson-Moss (and the DTPA for misrepresentation).
