S.D. Codified Laws § 32-6D-2
If a new motor vehicle does not conform to any applicable express warranty and the consumer delivers the motor vehicle to the manufacturer or its authorized dealer and gives notice of the nonconforming condition during the lemon law rights period, the manufacturer of the motor vehicle shall make the necessary repairs to the motor vehicle to remedy any such nonconforming condition. The repairs are required even after the expiration of the lemon law rights period if notice of the nonconforming condition was first given during the lemon law rights period. However, the manufacturer's obligation to repair the nonconforming condition does not extend beyond the period of twenty-four months following delivery of the vehicle or twenty-four thousand miles, whichever occurs first.
