My car which is FWD, not AWD, is exhibiting the same behavior that the recall for the AWD Equinox has. With Adaptive Cruise engaged the car ds not slow down or brake when approaching vehicles in front of it. I have to intervene and apply the brakes to prevent hitting the vehicle in front. Also, with ACC on the vehicle will accelerate on its own. I have to intervene to slow the vehicle down. For example, I set the ACC to 68 mph, all of a sudden it starts speeding up. I had to intervene when it hit 73 mph as it approached vehicles in front of me without slowing down.
