Hello! I’ve had a KIA Sportage GT Line NQ5 for a month now. In my sportage, the front seat heating takes quite a long time both on the driver’s and the passenger’s side. But for my feeling it only heats in the thoracic vertebra area (upper back) and in the lower leg area. At the seat and in the lumbar vertebra area (cross), where it would be most important for me, it remains almost cold in my opinion. I was also at the KIA dealer today. I mean, if it basically works, you can’t do anything. I meant that it just doesn’t work for my feelings in some areas. You could only ask KIA if you can do something there. He wasn’t willing to feel the differences with his hand, and only meant that feelings can be different from one person to another. I just find this behavior a cheeky one. What are your experiences with the seat heater? The seats also have a seat ventilation. Can it have something to do with it? Thank you for your answers. Greetings Claus
