Turn signal behavior

[Dexterryu]

Morning all, I'm hoping everyone can shed a little light on a potential issue I'm having with my turn signal. I do NOT have auto pilot but since the update that enabled assisted lane keep assist I use my turn signal to notify both the car and other drivers much more when I'm changing lanes.

Here is what his happening...

When I press my right turn signal (not to the clicked position like I would for a turn) it blinks 3 times and I change lanes. No problem.

When I press my left turn signal, again not to the clicked position, it stays on forever until I manually turn it off or make a full turn. Is this normal? Maybe I have some sort of faulty mechanism in my turn signal stalk?

That's exactly how mine works. I thought I read that the left is supposed to render the 3 blinks as well, but nope (unless I'm doing something wrong).

They should both work the same.
I would set up an appointment in your app to have it looked at.

Mine does the same on the left side from time to time. No rhyme or reason when it does it. I have read that there was an issue with the earlier builds (mine is Sep. 2018) and they have had to make a parts swap to correct it. I haven't bothered to have Tesla fix it, but they should be able to swap out the part if you contact them.

Mine has a March '19 build date.

My October 2018 build does something similar. Sometimes it’s 3, sometimes it’s forever. It’s definitely not it the clicked position.

March 2019 build here. Same exact thing. Pretty annoying.

Time for a service appointment.
April 19 build for me, no problems.

Yep, light tap is 3 blinks, left side or right side. If it’s not doing that, schedule service. Mobile Service can apparently do this very quickly (if available in your area).

I had the same problem when I first picked up my Model 3. They need to replace the steering control module (or something like that, I don't remember the exact name). Mobile service can do it in about 20 minutes.

Sept. '18 build, this was issue for our car also, but we never contacted SC about it continued to use the signals. After some months it has been working as designed. In our case I believe it was just needing a break in period.

I just wonder, all the signal units replaced, how many just needed a break in.

Not normal. And not unheard of, as you can see from the responses so far. My Aug 2018 Model 3 behaves the same way yours does. I suppose I should set up a Mobile Service appointment and get it fixed...

 

[Dexterryu]

Mobile service scheduled for tomorrow. Thanks for everyone's reply.

Definitely a sticky part, and known issue. Mine was replaced the first time I came in to the SC for service.

Mobile Service fixed the issue by replacing the unit.
