Have been having the same issue with the driver door not unlocking if I place my hand inside the handle. This occurred about 20% of the time so it was frustrating to find out what the issue was. The dealer could not help resolve the issue and even replaced the door handle as part of the guarantee. But, I found out recently that if I try to unlock the driver door with my hand inside the handle and doesn't work, I slightly touch my leg (to ground myself) and then it works 100% of the time. So, my thinking is that my hand was not making an electric current to unlock the door, but touching my leg somehow enabled my hand to unlock the door by conducting electricity. Does this make sense?
