§ 2-725. Statute of limitations in contracts for sale.
(1) An action for breach of any contract for sale must be commenced within 4 years after the cause of action has accrued. By the original agreement the parties may reduce the period of limitations to not less than one year but may not extend it.
(2) A cause of action accrues when the breach occurs, regardless of the aggrieved party's lack of knowledge of the breach. A breach of warranty occurs when tender of delivery is made, except that where a warranty explicitly extends to future performance of the goods and discovery of the breach must await the time of such performance the cause of action accrues when the breach is or should have been discovered.
(3) Where an action commenced within the time limited by subsection (1) is so terminated as to leave available a remedy by another action for the same breach such other action may be commenced after the expiration of the time limited and within 6 months after the termination of the first action unless the termination resulted from voluntary discontinuance or from dismissal for failure or neglect to prosecute.
