I had the same thing happen but for me it was because the vehicle was locked and I did not have my key fob on me..If the doors are locked you will not be able to open the back hatch without the fob, if the vehicle is not locked you will not need the fob.. Hopefully this is just a learning curve issue as for me but things do go bad and you still have the warranty. Thats what warranties are for.. Good Luck to ya.Only 600 mi on new GV70 and the trunk refuses to open from outside button on wiper housing. It works from key fob, inside button, but not from manual pressure on the back button. Anyone know a workaround? Did I hit a switch by mistake to deactivate?? Such a nice car, hate to start having issues.
