I have a 2020 impala premier. I noticed my collision avoidance in settings had a check mark a says off. When I try to change it to on it stays off with the check mark. Any idea what is not allowing me to switch between off an on in settings

 

HHow long have you owned the car? Any idea if you have seen this turned on in the past? Maybe a feature not installed???

 

I have owned it for 3 years. The system has always worked.it was set to on when I first got my car.my adaptive cruise is working fine. My gap can be set on the steering wheel.
