    I have a Model X 100D with software version 2019.16.3.2

    After the last update I have a lot of issues with the autopilot function:
    • When driving in Autopilot, I can no longer change lanes when turning on the indicator. Instead I get a message 'Lane change inhibited'. This makes the autopilot virtually unusable
    • When in cruise control, after overtaking a car and going back to the first lane, the car (frequently but not always) slows down for no apparent reason. This results in cutting of the overtaken car...
    • When approaching a slower car, the cruise control slows down much earlier, even when distance is set to 1. There is still a lot of space between my car and that in front of me and makes it much harder to change lanes if other cars are in the left lane
    • The car brakes frequently for parked cars, even when the car is in a clearly marked space
    • When passing a car on a road with no lane markings, the car brakes frequently but only when the other car is almost completely passed...
    • When driving and no obstacle whatsoever is visible, the car brakes from time to time
    I did not have these issues before the latest update

    Is this 'normal' behaviour for this update? Or is there an issue with my car?

    Model S with 2019.20.4.2

    For the first issue I would suggest a quick tap on the indicator and the car will change line by itself when able.

    For the other issues I regret to say that I think I have all of them since 2019 updates, and I can say that I cannot trust AP anymore, till the point that in its present state I consider AP dangerous, at least in my car.

    I have contacted my SC for a calibration of the cameras with no luck until now.

    Model X with 2019.20.4.2

    Our X will brake hard when approaching an overpass, about 50% of the time. The lower the overpass the more likely.
    It will LURCH to the right at some bumps; either potholes or entering and exiting a bridge. This is scary!
    It will slow down when switching back to my lane after passing. Could cause an accident (get rear-ended) or a road rage incident.

    I use the assist, but watch it like hawk. I really don't expect my X will ever be able to "self drive".

    Different thread, but we have all the front end issues that I have read about on this site.
