Hello everyone, I am new to the forum. I have a 2007 Santa Fe and am having a problem..... when I start my car on a freezing cold (-28 degrees Cel. in Canada) it starts up no problem at all. I then drive it for 15 mins./pop into a store for 15 mins and when I come back out the car will not start. It cranks OK and all the proper ICONS light up on the dash but it will not start. I have to sit and try it over and over for about half an hour and then it magically starts again. Did anyone else have this problem and more importantly how did you fix it?
