    I searched around and can't find any posts about this, but I wanted to see if anyone has has the same issue.

    Starting this week, my left lane change blinker doesn't work. You know when you only push the stalk down part way and get three blinks? Now I can't do that -- the blinker just stays on. It is only a problem on the left side, as the right one works fine.

    The stalk still feels normal when I push it down, so it doesn't seem like a mechanical problem. Is there a way that it could be software related? Am I the only one?

    If it helps, it's a 2019 Model 3 Performance FSD with HW3 and software 2020.36.10

    Also, I guess I should mention that this has nothing to do with AP. I am talking about when I am driving on the highway and use the blinker.

    You need a new stalk. It’s under warranty. Happened to me... had to replace it... twice.

    Same! It drives me crazy - I’ll tap the stalk to change lanes and occasionally it’ll do nothing, but by that point I’m starting to change lanes so the lane departure warning yells at me. Very frustrating.

    Have the same issue and it was replaced in 2019 but kept occurring, just replaced for second time the other day. Mobile service tech said it's a very common issue but they are interestingly still using the same part revision so despite it being faulty they haven't updated the part.

    I have a theory about sampling. I feel like if I flick any stalk, odds are the action will not register, but if I do more of a momentary hold, at either the soft or hard stop, it does much better. I wonder if it needs more than an instantaneous contact in order to register.

    There was a run of this issue back in late '19, our car had the same issue for a while. Then it wasn't, in our case it just needed breaking in. We still have the oem turn signal module and it works as expected to this day.

    agree.

    ive a 2020 but sometimes i wont push the stalk down far enough and the blinker wont sense, but if i am more deliberate and more "momentary" as you describe, 100 out of 100 it works.

    that's not to say there could be some faulty stalks - looks like there are some out there...

    I don't like the toggle stalk. I want the switch stalk where the stalk stays like other cars.

    This stalk does stay doesn’t it ?
    It’s just like the other cars I’ve had.

    I believe My 1978 Honda Civic had a toggle.

    Yeah, you may need a new steering control module or something like that, the unit that contains both the left/right stalks. Mine had the opposite issue with the right blinker where I would pull it all the way but it would only blink 3 times.

    It was replaced, but I still get the occasional time when it doesn't work as expected. The frequency of this decreased over time, so there was definitely some kind of break-in period.

    I have the same issue, left only: sometimes is does 3 blinks and sometimes it stays on and you have to manually stop it. Very frustrating. I am about to file it as a service issue.

    Exact same issue with our Model 3 built in late December 2019.
