A private action to enforce any liability created under this part may be brought within two (2) years from the date on which the liability arises, except that where a defendant has materially and willfully misrepresented any information required under this part to be disclosed to a consumer, and the information so misrepresented is material to the establishment of the defendant's liability to that consumer under this part, the action may be brought at any time within two (2) years after discovery by the consumer of the misrepresentation. No action brought by the attorney general and reporter shall be subject to the limitation of actions contained herein.
