W. Va. Code § 47-11F-7: Warranty claims.

If after the termination of a contract or agreement, the dealer submits a warranty claim to the supplier for work performed prior to the effective date of the termination of such contract or agreement, the supplier shall accept or reject such claim within a minimum of forty-five days from the day the supplier received the warranty claim. A warranty claim not rejected before the expiration of such forty-five-day period shall be deemed to be accepted by the supplier. In the event a warranty claim is accepted by the supplier as prescribed in this section, such claim shall be paid by such supplier not later than sixty days from the date the supplier received the claim.
