In addition to the remedies provided in this act, a court reviewing a consumer contract may reform or limit a provision so as to avoid an unfair result if it finds that:
If the court reforms or limits a provision of a consumer contract, the court shall also make orders necessary to avoid unjust enrichment. Bringing a claim for relief pursuant to this section does not entitle a consumer to withhold performance of an otherwise valid contractual obligation. No relief shall be granted pursuant to this section unless the claim is brought before the obligations of the contract have been fully performed.
