Hi, Ed;
I had that feature on my old '11 Impala, and it was a nice feature. I just got a '24 Equinox and tried to test it last night by driving a couple of miles down a deserted road with my signal on. I never got any kind of alert. So it doesn't appear that the feature exists on newer Equinox models. My Nox has every other feature under the sun, so it seems like that would have been something Chevy would have kept on their newer vehicles. I'll research a little more, and let you know if I find anything else.
The only good thing for me is that the "blinker blinker" sound is pretty loud on this car, and I can clearly see the blinker signal lights on the dashboard (unlike my Impala, where they were perfectly hidden behind the steering wheel). So that should help to keep me from unintentionally leaving them on.
Jeff
