Turn signals won't self cancel
Take a look at the back side of the steering wheel hub- there should be a heavy circular ring with a 90* finger pointed straight out. This finger is what trips the cancelling switch. If it is missing or incorrectly indexed the signals will not self-cancel.
As the wheel spins to return to center, that finger contacts one of these two parts of the signal switch, tripping it off.
So if the finger is missing or clocked way off, it will not cancel.
It is a beeotch to move (just held in place by spring tension), but I have seen it missing.
