Acadia Lane Departure Alert not working

[catpartsman]

Ok, so i tired searching for this but turned up no results. I’m sure I’m not searching right or something. Anyway, our 2017 Acadia has the lane departure warning system along with steering assist. We have the lane departure alert set to vibrate the seat. When traveling to Florida last week, I noticed the seat doesn’t vibrate when crossing the center or right line without using a blinker. Is this a common issue or am I missing something?

 

My 2015 Sierra has this system and it works just fine.

 

I’m just looking for input before I have to make an appointment to take it to the local stealership.
