Okla. Stat. tit. 15, § 15-910.2

A. A manufacturer who sells an assistive device to a consumer,

either directly or through an assistive device dealer, shall furnish

the consumer with an express warranty for the assistive device. The

duration of the express warranty shall be not less than one (1) year

after first delivery of the assistive device to the consumer. In

the absence of an express warranty from the manufacturer, the

manufacturer shall be deemed to have expressly warranted to the

consumer of an assistive device that, for a period of one (1) year

from the date of first delivery to the consumer, the assistive

device will be free from any condition or defect which substantially

impairs the value of the assistive device to the consumer.

B. If a new assistive device does not conform to an applicable

express warranty and the consumer reports the nonconformity to the

manufacturer, the assistive device lessor or any of the

manufacturer's authorized assistive device dealers and makes the

assistive device available for repair before one (1) year after

return delivery of the assistive device to a consumer, the

nonconformity shall be repaired at no charge to the consumer.

C. If, after a reasonable attempt to repair, the nonconformity

is not repaired, the manufacturer shall carry out the requirement

set forth under Section 4 of this act.
