I have an IS 250 F-Sport with Heated seats. There are 3 settings - low, medium and high. I can not feel warmth under any setting. Dealer says seats are working to specification - but if I can't feel any warmth, I don't believe them. I have owned Lincolns, Cadillacs, BMWs and have never had an issue where the heated seat wasn't physically warm to the touch - particularly under the high setting.
What does the specification say? What should be the temperature output on Low? Medium? and High? I have called several times and can't get any answers.
My loaner RX had operational seats that warmed up within 2 miles of dealer. Yet, I have had my seats on for hours and feel absolutely no heat.
