The Missouri lemon law covers any new motor vehicle being transferred for the first time from a manufacturer, distributor or new vehicle dealer; that has not been registered or titled in the state or any other state; and that is offered for sale, barter or exchange by a dealer franchised to sell, barter or exchange that particular make of new motor vehicle. This includes demonstrators or lease-purchase vehicles as long as a manufacturer’s warranty was issued as a condition of sale.

The lemon law does not cover used vehicles, and appears not to cover leased vehicles unless acquired through a lease-purchase. The lemon law does not cover commercial motor vehicles, off-road vehicles, mopeds, motorcycles, and recreational motor vehicles other than the chassis, engine, powertrain and component parts.
