couple weeks ago I had the car in the dealer to see why the battery went dead twice. They couldn't find any problem but they did a couple of software updates on the CUE and the trunk latch. The CUE seems a little more responsive and the climate page looks different. Anyway, I used to be able to walk up to the trunk and push the rubber button and the lid would open. Now it won't open that way even if I try to push the key fob trunk button. But will open if I push the button on the inside of the door. I thought I would have to bring it back to the dealer. Today I was sitting in the car and thought maybe if I hit the door unlock button first then push the rubber trunk button. Bingo, it works that way. The doors need to be unlocked before the external trunk button works. Must have been a change in the software update.
