South Dakota Lemon Law does not cover business vehicles. However, the federal Magnuson-Moss Warranty Act states that the manufacturer of any product — from your toaster to your lemon business vehicle — must abide by the warranty.
Unlike the South Dakota Lemon Law for cars, which requires you to go into arbitration or mediation, you need to sue manufacturers and dealers in a court of law. The window of time to initiate a lawsuit is small, so speak to a Lemon Law attorney if your vehicle has been in the shop three times for the same problem. If your case is successful, the manufacturer will have pay for attorneys' fees, so you shouldn't have to pay for representation.
As with other types of Lemon Law claims, organization is key to presenting a convincing case. Keep spotless records of every malfunction and problem you have had with your vehicle since you bought it. Save all of the paperwork that you received every time you brought your vehicle to be serviced. Catalog the days the vehicle spent in the shop and out of your possession. Remember, the more organized your evidence is, the more likely it is that your attorney can win your case.
Make sure to send a Demand Letter via certified mail, return receipt requested, to the manufacturer. Sample demand letter.
