(a) It is presumed that a reasonable number of attempts have been undertaken to conform a new motor vehicle to the applicable express warranties, if the same nonconformity has been subject to repair three or more times by the manufacturer, its agents or its authorized dealers within the express warranty term or during the period of one year following the date of original delivery of the motor vehicle to the consumer, whichever is the earlier date, and the nonconformity continues to exist, or the vehicle is out of service by reason of repair for a cumulative total of thirty or more calendar days during the term or during the one-year period, whichever is the earlier date.

(b)If the nonconformity results in a condition which is likely to cause death or serious bodily injury if the vehicle is driven, it is presumed that a reasonable number of attempts have been undertaken to conform the vehicle to the applicable express warranties if the nonconformity has been subject to repair at least once by the manufacturer within the express warranty term or during the period of one year following the date of original delivery of the motor vehicle to a consumer, whichever is the earlier date, and the nonconformity continues to exist.

(c) The presumption that a reasonable number of attempts have been undertaken to conform a new motor vehicle to the applicable express warranties applies against a manufacturer only if the manufacturer has received prior written notification from or on behalf of the consumer and has had at least one opportunity to cure the defect alleged.

(d) The term of an express warranty, the one-year period 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.
