My guess is the parking brake mode fried the electromagnet causing the problem. Maybe maybe not.. But that is my guess. With that said maybe you ought not to tell the dealer all the details and let them just trouble shoot it. You might get all your brakes repaired under warranty. Yeah some might say that not right or correct. Maybe the PDI wasnt performed properly and the dealer failed to checker out the controller. Maybe the electromagnet was indeed faulty.. who knows but dont give the dealer all that info.. If you do plan on paying for a repair job.
