2007 Kia Sedona. My ESC light is coming on when i accelerate to get up to speed on hills. When I shut off the car and it is restarted the light is off. I have seen on utube where this is possibly related to the throttle position sensor. I do not have the loss of power they are experiencing. Is this a sign that I will start shutting down on me in the future? Is this the repair the dealer would preform If I took it in?
