Since last winter we had a problem with drivers heated seat staying on ,mentioned it to service manager and he kind of put it off. Was nearing end of warranty so I had them check it when I took it to them for a bad alternator, see other post. It went back and forth a few times 3 or 4, they would check it and say it was fine and when I got back in it the seat would shut off in 3 or 4 seconds. Finally they decided to replace a module. Had to wait 10 days for a part, they put it in and it stopped working the next day. I took it back and they kept it for 4 days saying they were waiting for a part to be overnighted. Took the car back for weekend then back to the dealer when the part came in, then had to wait another day for a different part to come in. So I guess they had to replace the heating elements and wiring harnesses for the seat
