The Magnuson-Moss Warranty Act in South Dakota

How the federal Magnuson-Moss Warranty Act (15 U.S.C. § 2301) supplements South Dakota's lemon law — federal-court access in D.S.D., § 2310(d)(2) attorney fees, and a 4-year runway.

The federal Magnuson-Moss Warranty Act, 15 U.S.C. § 2301 et seq., is the third statute in a South Dakota vehicle-defect claim — alongside the South Dakota Lemon Law and the Deceptive Trade Practices statute. It is especially useful in South Dakota because the lemon law has a short reporting window and the DTPA is weak.

What Magnuson-Moss adds

  • § 2310(d)(2) attorney fees — fees “based on actual time expended” to a prevailing consumer.
  • Federal-court access — D.S.D. for cases over $50,000.
  • A 4-year limitations runway (borrowed from the UCC, SDCL § 57A-2-725) — longer than the lemon law’s 3-year SOL.
  • Implied-warranty leverage (merchantability under § 57A-2-314).

§ 2310(d)(2) — the federal fee provision

15 U.S.C. § 2310(d)(2) provides:

If a consumer finally prevails in any action brought under this section, he may be allowed by the court… costs and expenses (including attorneys’ fees based on actual time expended)…

Federal courts award these fees liberally in successful warranty actions. In South Dakota — where the DTPA has no treble — Magnuson-Moss is a valuable parallel fee basis (and a federal-venue option), alongside the lemon law’s own § 32-6D-8 fees.

When to choose federal court (D.S.D.)

  • Amount in controversy exceeds $50,000 (the Magnuson-Moss threshold).
  • High-value vehicle (luxury, EV, heavy-duty pickup under the 15,000-lb threshold).
  • Used vehicles or leases outside the lemon law’s reach (leases aren’t addressed by § 32-6D).

Implied-warranty leverage for used vehicles and leases

Magnuson-Moss federalizes South Dakota’s implied warranty of merchantability (§ 57A-2-314), useful for used vehicles and leases (which the lemon law doesn’t address), with a 4-year runway.

Bottom line

Magnuson-Moss gives South Dakota consumers a federal-court option and a fee hook with a 4-year runway — particularly valuable for leases (which the lemon law doesn’t address), used vehicles, and high-value cases where the weak DTPA falls short.
