I've had the issue since I bought the car but the traction control is always difficult to turn off. First start the car and try to turn it off it won't, you can sit there and hold the button for ages and nothing happens. Keep trying to press it and eventually the light will flash once or twice then nothing. Turn the car on and off, nothing, then it will just randomly turn off and be fine. Checked the switch and it's fine. Any ideas?
