The exterior gas access has a switch on the driver door panel. That switch failed on my 76 yr old mother-in-law at a gas station and she did not know about the emergency panel in the rear hatchback area. She has been using that until she finally save up enough money from her social security to pay Hyundau $200 to fix it. She has other problems that I have added to this site as well. She is the original owner but these issue are giving Hyundai a black eye as far as Quality and Reliability are concerned. They should recall and give her back her money!
