Does this vehicle have heated, and cooled seats? If so, the medium for heat/cool is a thermo-electric device. The chance of all four of these being faulty is rare. Most common concern, is melted terminals from poor connection, at the climate control seat module, under the passenger seat. Pull the connector with the large red/white wire, you will either find it, or the ground terminal melted. From there, the connector, terminal, and module need replaced. It looks like you should still be well under manufacturer warranty, you could let the dealer fix it.
