Bermuda triangle, space aliens, gremlins, coincidence or maybe a scientific explanation. I parked my 2021 premium luxury XT6 at a restaurant at a large tourist destination. When we ruturned to our car and started it up the navigation did not work. After driving a few miles we stopped and restarted the car and navigation worked again. It has worked ever since. This was about a year ago. Now this last week we went to the same restaurant and parked in the same area, within a few dozen yards from our previous visit. I had to press the door handle button 2 or 3 times to get the car to lock. When we returned after eating, pressing the door handle button would not unlock the car. My wife tried her door and it did not work. car was locked. I tried the unlock button on the fob and doors unlocked. Once in the car everything worked as normal and still does two days later. I did put fresh batteries in our fobs a few months ago so can't be that. I am not going to greedy motors and have them charge me $$$$ only to say they have no idea what happened. I am going to park on the other side of the building next time I go there, no gremlins there.
