Hey, folks,
I'm having an issue with AutoPilot on my Model 3, have brought it into the shop, and the technician there says that this is "normal behavior" so I wanted to check in with a few other owners before making this into something bigger. The behavior in question is that when I'm in AP, and hit the right turn signal to change lanes, about a quarter to a third of the time, the car begins the lane change then aborts it part way into the desired lane. Sometimes it does a "shimmy" where it begins the lane change, aborts the lane change coming back into the original lane then completes the lane change normally.
You can see it occur in these clips from the front-facing webcam:
Video 1 - https://youtu.be/zLuTyAQOi9I - failed lane change at 38 second mark
Video 2 - https://youtu.be/FEZYMUrTUcE - failed lane change at 35 second mark (I then completed the lane change myself)
This has happened on well-marked, well paved highways with very light traffic and no obstructions. The initial service description they sent a few days after I brought the car in said they were unable to reproduce the problem, and the car seemed to be behaving normally. So they suggested I pick up the car and let them know/bring it back in if it happened again. But that's super inconvenient to me due to the location of the service center. I suggested they try to reproduce it again, and they suggested they would start charging me storage fees if I didn't pick up the car immediately.
So I picked up the car this evening, did a test drive with the technician where we exactly reproduced the problem on the second lane change. The technician told me that they did find an error in the log from the first incident in the video and that the car said "bad lane change health." He said he sees this thing from time to time and it's perfectly normal.
But I owned a Model 3 RWD for 6 months and this never happened. Upgraded to a Model 3 Performance in November and it has happened at least 20 times since I got the car. Also, it never happens when changing lanes to the left, only when changing lanes to the right. So I suspected a hardware problem with the sensors.
Has anyone else experienced anything like this? Any suggestions as to escalation (other than writing a scathing expose about Tesla's low quality of service)? That's always an option, but I like to give them the benefit of the doubt first.
