This is very interesting since this problem NEVER occurred to us before in the past 5 new cars that we owned (this 2018 Kicks SR is our 6th). So after turning off the car and closing the doors, when I go to lock with the fob, it doesn't lock nor make any sound nor show any indication that a signal went through. Somehow ONLY the button on the front drivers and passenger doors only unlock/lock. And another interesting part is that the fob battery isn't dead, since I didn't have to place it near the push-button ignition. So, any clue on what is causing this issue?
