Hi I have a 2019 Fit LX and think the automatic blinker shutoff is busted. The blinker only shuts off automatically if it’s a 90 degree turn. I swear it did it when I did a lane change or it even just shut off after a while if I left it on. How does it function normally please? Also is it expensive to repair?

 

The turn-signal cancel mechanism is PHYSICAL. It can't turn itself off without steering movement.
For lane changes, I don't normally fully engage the turn signal. I just tap it to cause 3 blinks.
If I do fully engage it, I have to manually return the stalk to turn it off.
So sounds like yours is working fine.
