Has anyone noticed that the turn signals don't always turn off, even when you make a turn that you feel like should be sharp enough to trigger it to shut off?

I work at a dealership, and I've noticed this with several of the 12's we have, as well as my own. Yet, none of the 11's had this problem.

 

My '08 does this.

 

so does the 11's, I also end up driving like 2 miles after i changed lanes sometimes and forget I had turned my signal on. Its annoying something should come on the dash after 30 seconds or so.

 

Is this working as intended?

 

My 12 does this, I changed the sound to the beeps instead of the clicks and I usually catch it a little faster.

 

My '11 does the same... therefore, I don't fully engage the turn signal switch anymore... I've gotten used to slightly pressing down on the switch without applying too much force to turn on the turn signal in whatever direction I want for a few seconds; roughly about 3 seconds, then the light turns off and the switch remains in its center position

 

I have a 12 and I never really use the full click. Just the half way thing that give the 5 blinks. The couple of times I did use them they seemed to work. Not sure where you guys are from but here in So Cal using your blinker just informs the guy behind you that he should speed up so you can't get over. I NEVER use them unless I am making a turn that requires me to slow down in traffic. Just don't want to get rear ended. But for the freeway they make no sense.
