I don't know for sure, but I would assume they work off a split voltage.Heated seats are actually a concern for me (thinking about adding a second '11 Sonata to the stable; 2.0T Limited). My ownership experiences with heated seats thus far are with European cars, which typically have at least three heat settings, if not more (I've had cars with up to six). And, they don't cycle on and off, but rather they are thermostat-controlled and will reach and then maintain the selected temperature. My brother had a Nissan 350Z and the heated seats in that car (High and Low) were strange in that the heat cycled on and off, it just stayed on longer on the high setting. My stepdad's 350Z, of newer vintage than my brother's was, behaves the same way. My experience has been similar with other Japanese cars, and American cars. Do the Sonata heated seats behave the same way; i.e., they cycle on and off rather than reach and maintain the selected temperature?
My dad's got an '07 Acura RL and it seems heated seats are something of a weakness for Honda/Acura because I've noticed the same thing. They are VERY slow to warm up.I traded an 09 Accord for the Sonata. The Accord had heated seats. The Sonata's seats heat up quicker than the Accord's and get a tad warmer. By the time the Accord's seats heated up to the point where they were actually doing any good, the heater was blowing out hot air and the cabin temperature was getting comfortable.
My '09 VW Jetta heats the cushion and backrest on the passenger's seat. By the way, the occupant sensors for the passenger airbag is typically located in the bottom cushion, not the backrest. It needs to detect the weight of the occupant in order to know if the airbag should deploy or not; i.e., under a certain weight (child) the airbag will not deploy.On a related topic, does anybody know if the passenger seat (I'm sure rear is only bottom cushions due to no wires on the reclining backrests) has warmers on the backrest or just the bottom cushion? Never had a car with heated rear seats, but all other cars I've had only heated the cushion on the passenger seat due to airbag sensor being on the backrest. Haven't found out on my newest 2 cars yet, but curious. Thx.
Correct. Guess should have been more specific. The electronics are on the backrest. At least that's what Acura and Lexus claimed as recently as 2004. Or could have been just an excuse not to put warmers there :grin:. I guess we'll find out in a few weeks/months what is it with Hyundai. Take care.By the way, the occupant sensors for the passenger airbag is typically located in the bottom cushion, not the backrest.

As for the heat produced - they seem plenty sufficient. The seats in my wife's Sonata seem to heat up just as quickly as my G37 and get about as warm as my G on 'level 5' (of 6); I usually find myself changing to low setting after 5-10 minutes.I'm thinking my seats are exceptionally weak... I definitely haven't experienced the heat I seam to be hearing from most of you. For me the high setting just becomes barely suitable after 5+ minutes and doesn't really heat up any more.... and I have turned on the passenger seat to low and waited about 5 minutes to feel it with my hand and it doesn't even feel warm.
I guess the only question is if it's poor enough to actually complain about it, or if that wouldn't even do any good/not worth it. I'll be doing some more testing as it continues to get colder...
Mine is the same; I never use the Low setting.Rather then raise a new topic, bought this one up from the past.
My 2013 Limited seems to have the lamest heater I have ever felt (or not felt in this case). Low is not even noticeable, High is noticeable and it becomes somewhat warm. Is this good as it gets? them seem barely useful. My old Subarus would get warm on low, and HOT on high.
I took it in to the dealer to complain, they measured it and said both seats heat up to 78F. Is that typical?
