A manufacturer shall pay a properly submitted warranty claim of an authorized dealer within 30 days after receiving the claim from an authorized dealer. Unless a manufacturer issues a written notice of disapproval under Alaska Stat. § 45.27.170 within the 30 days, if a manufacturer fails to pay a claim within 30 days after receipt, the failure is considered an acceptance of the claim as submitted, and the manufacturer shall pay the authorized dealer interest at the rate of 1.5 percent a month on the claim.
