Just bought a 2012 genesis r spec about a week ago. My back door passenger side won't open from the outside. It will open from the inside. Was working early same day now it doesn't work. I was trying to unlock the doors by pushing the button on the passenger door but it wouldn't unlock the doors so I used the key fob to unlock it. Went to open the back door and it wouldn't open. All the other doors open from inside and out.
