I purchased a 2013 Santa Fe sport from Coconut Creek automall and I had this problem from week one. my trip A meter resets itself and I have gone back to the dealer many times. they put it on the computer and they say they can't find anything wrong. I went on line to one sight that has expert mechanics and he researched and came back with three soloutions when I went back to the dealer with that would not even look at it I have called and written to Hyundai in Calif and the general manager of Cocnut creek Hyundai and they din!t do anything
