Only time it hasn't worked for me was today when I needed to shift right from slow moving traffic to almost dead stopped traffic. I found a gap that worked for me but the autopilot refused to try it.

Mine worked the first day I had the car, then didn't work for the subsequent two drives, then worked again yesterday. No rhyme nor reason, and very little traffic each time.
There is a problem with auto-lane change at the moment. So far this has been the most reliable part of the autopilot package for me. But after the latest firmware update it goes haywire.
The dash indicates that there is a clear lane to change into. So hand on the wheel, set the blinker and now the "clear lane" just disappears from the dash. Nothing else happens, no dashed blue line, no change in speed nothing.
Then sometimes it suddenly works perfectly again. It's almost as if Tesla tweaked the "clear lane" code and it broke in a subtle way.
I tested this on an almost completely empty motorway and it didn't work reliably most of the time. A huge change down from the almost 99% reliability I've had so far.
Note this was in a Model S, but the hardware is the same.
That turned out to be my problem too. We created a new profile, but forgot to enable auto lane change on it. Then we didn't pay attention to which profile was active (because we thought they were triggered by which person got into the driver's seat with their fob) and didn't figure out until seeing your post that the profile was the problem.my problem with it was pilot error originally... Creating a new driver profile switches it to off, you must go back and turn it back on.
We tried having it lane change onto an exit ramp - it slowed down and started to take the exit but then I had to take over because it was still going to fast and not turning onto the ramp correctly. Maybe if I had been following a car exiting it would have worked? I'll have to try it again.
I was in an exit-only lane, following another car, and the car didn't seem to want to follow the exit (despite very good markings). It seemed to want to continue on the roadway and took me to the left side of the exit before I took over. I haven't had time to experiment a bit more, but it seems like there are more forces in play.
Did you leave the turn signal on? Turning it off too soon will abort he lane change.
Was the lane next to you crowded? I've seen this when there's A LOT of traffic and so the camera cannot clearly see the lines and/or gaps.
After driving with the autopilot for the last couple weeks, I'm amending my original opinion of the system and now feel very satisfied that it's working exactly as advertised and described in the operator's manual and release notes. Is it perfect, no, but it still works to the best of its ability as designed. I'm sure it will only get better over time as it matures in capability.
