I have not had Ice mode once on my '18 SS 1LE. The key is in how you apply the bakes. If you have very grabby pads and you tent to jump on the brake pedal, (instead of applying the 20/80 rule and letting the weight transfer forward) your chances of getting ice mode increase.

And of course loose surfaces can also trigger ice mode too.
The pedal was hard the entire time, just felt like the ABS wasnt letting the pads grab.
