Minn. Stat. § 59C.12

This chapter applies to all vehicle protection products sold or offered for sale on or after January 1, 2008. The failure of any person to comply with this chapter before January 1, 2008, is not admissible in any court proceeding, administrative proceeding, arbitration, or alternative dispute resolution proceeding and may not otherwise be used to prove that the action of any person or the affected vehicle protection product was unlawful or otherwise improper. The adoption of this chapter does not imply that a vehicle protection product warranty was insurance before January 1, 2008. Nothing in this section may be construed to require the application of the penalty provisions where this section is not applicable.
