Welcome Fen Bass. There is no recall or bulletin that I'm aware of for the heated seats. I would think there would be more owners having the same problem, yet no bulletin. Next trip to the dealer I am going to bring it up again. Although it's out of the basic warranty I will pursue it with them. I would like them to show me that it is working.

Make sure you turn the seat heater on before shutting down the engine. According to the manual it needs to be on prior to remote starting. After a manual start my seat gets too hot to leave on for more than 5 minutes, even on the lowest setting, so I forget to turn it back on before getting out of the vehicle. I don't use remote start very often.
