OK, I'm having nearly the identical problem to Juice. Picked up the car in late September (this is my second Tesla) and Iive on the SF peninsula, close to the Tesla engineering center. When AP is working correctly, the car is calm and solidly centered in the lane. When it's not working correctly it immediately steers for the left edge of the lane and is much less stable, seeming to bounce off the left-hand lane markers and wandering toward the middle of the lane and back. It's particularly egregious in turns. The lack of stability in this mode is enough to make AP uncomfortable and cause concern that other drivers might be worried about my driving. The problem is intermittent and on longer drives of more than one hour, the car seems to eventually fix itself. The behavior is very obvious to anyone in the car and is clearly visible on the display which shows the car driving on the left lane marker. No, you don't need someone following behind you to tell you that the car is driving on the left lane markers and not in the center of the road.
I contacted Tesla service about this and the techs responded that they could see some errors in the camera logs and asked that I provide timestamps for when the problem was happening. After providing a series of time stamps Tesla service texted me and asked that I set up a service appointment.
Brought the car in and they had it for over a week, continually extending the estimated service time and telling me that the techs were working with the engineers on the problem. Eventually, I was told the car was done and come pick it up. At the service center, I was told that the techs reseated all the camera connectors and were not able to duplicate the problem. So I drove it home. And it still has the problem.
Today, I was having the front of the car clear wrapped and the guys doing the work called to tell me that one of the two connectors on both of the front rear-facing cameras was disconnected. This is the smaller coax connector. These guys do a lot of Teslas (half the cars on the street around here are Teslas) and this is the first time they've seen this. I have to assume that this connector is not used because if one of the side rear-facing cameras is not working, the car will not perform an automatic lane change to that side while in AP. It should also put an error message on the display. I don't have an error message and my car happily performs auto lane changes.
This is clearly a problem of some sort. It's not normal and certainly not safe operation of AP to bounce along the left-hand side of the lane. But it's intermittent (at least in my case) and Tesla does not seem to have a fix for it yet.
I plan to contact a couple of the engineers I know at Tesla and see if I can get some traction. I'll let you know if I find anything out.
