S.D. Codified Laws § 37-37-6
A consumer sustaining damages as a proximate consequence of the failure by a manufacturer to perform the manufacturer's obligations imposed under this chapter may bring a civil action against the manufacturer to enforce the provisions of this chapter. Prior to the commencement of any such proceeding a consumer shall give notice of a nonconforming condition by certified mail to the manufacturer and demand correction or repair of the nonconforming condition. If at the time the notice of a nonconforming condition is given to the manufacturer, a presumption has arisen that reasonable attempts to correct a nonconforming condition have been allowed, the manufacturer shall be given a final opportunity to cure the nonconforming condition. The manufacturer shall within seven calendar days of receiving the written notice of nonconforming condition notify the consumer of a reasonably accessible repair facility. After delivery of the farm machinery to the authorized repair facility by the consumer, the manufacturer shall attempt to correct the nonconforming condition and conform the farm machinery to the express warranty within a period not to exceed fourteen calendar days. If a manufacturer has established an informal dispute settlement procedure conducted within the state which is in compliance with federal rules and regulations, a consumer shall first exhaust any remedy afforded to the consumer under the informal dispute procedure of the manufacturer before a cause of action may be instituted under the provisions of this chapter.
