23' Sierra Denali BSM not working

KinkyDuramax · April 9, 2024

I just bought a 2022.5 (Refresh) Sierra Denali (W/ Reserve package). I did talk to the dealership, so It will be brought in Saturday to take a look why the BSM is not working. When traveling next to cars it does not alert on the mirrors that someone is in my blindspot. I was curious if anyone else has had this problem? If so, what did they end up doing to resolve it? I've came across one post on Google that someone had the BSM module replaced, but that's all I saw. Could it be a software update, or just a hardware replacement? It is still under factory warranty. Maybe it's something I need to toggle in the settings?

Are you getting any messages on the dash like system disabled or service blind spot? How about the indicators in the mirrors are they solid yellow/orange?

In the radio, tap on settings, go to vehicle and there should be a section for collision/detection systems. In that menu there should be options for all of the driver assist systems in the truck.

@newdude I am not getting any sort of alerts on the instrument cluster. The only thing I turn off all the time is the Auto-start stop and the lane keep features. I dislike it steering me outside of the lane. Its the button next to the Parking Sensors to the left. That is the "lane keep assist" button.

The indicators have the little car with the star but they do not light up.
