Missouri Revised Statutes Title XXVI. Trade and Commerce § 407.573. Warranty extension, when--complaint remedies information to be furnished--notice to manufacturer required--manufacturer's duties, time limitation

1. The terms, conditions, or limitations of the express warranty, or  1 the period of one year following the date of original delivery of the new motor vehicle to a consumer, whichever expires earlier, may be extended if the new motor vehicle warranty problem has been reported but has not been repaired by the manufacturer, or its agent, by the expiration of the applicable time period.

2. The manufacturer shall provide information for consumer complaint remedies with each new motor vehicle. It shall be the responsibility of the consumer, or his representative, prior to availing himself of the provisions of sections 407.560 to 407.579, to give written notification to the manufacturer of the need for the repair of the nonconformity, in order to allow the manufacturer an opportunity to cure the alleged defect. The manufacturer shall immediately notify the consumer of a reasonably accessible repair facility of a franchised new vehicle dealer to conform the new vehicle to the express warranty. After delivery of the new vehicle to an authorized repair facility by the consumer, the manufacturer shall have ten calendar days to conform the new motor vehicle to the express warranty. Upon notification from the consumer that the new vehicle has not been conformed to the express warranty, the manufacturer shall inform the consumer if an informal dispute settlement procedure has been established by the manufacturer in accordance with section 407.575. However, if prior notice by the manufacturer of an informal dispute settlement procedure has been given, no further notice is required.

3. Any action brought under sections 407.560 to 407.579 shall be commenced within six months following expiration of the terms, conditions, or limitations of the express warranty, or within eighteen months following the date of original delivery of the new motor vehicle to a consumer, whichever is earlier, or, in the event that a consumer resorts to an informal dispute settlement procedure as provided in sections 407.560 to 407.579, within ninety days following the final action of any panel established pursuant to such procedure.
