(a) It shall be presumed that a reasonable number of attempts have been undertaken to conform a motor vehicle to the applicable express warranties, if:

(b) The term of protection and the thirty-day period shall be extended by any period of time during which repair services are not available to the consumer because of a war, invasion, strike or fire, flood or other natural disaster.

(c) It shall be the responsibility of the consumer, or the representative of the consumer, prior to proceeding under § 55-24-103, to give written notification by certified mail directly to the manufacturer of the need for the correction or repair of the nonconformity.

The authorized dealer shall upon receipt forward the notification to the manufacturer. If, at the time the notice is given, either of the conditions set forth in subsection (a) already exists, the manufacturer shall be given an additional opportunity after receipt of the notification, not to exceed ten (10) days, to correct or repair the nonconformity.
