+1 I have ACC on my 17 Volt and 17 GMC Acadia and use it almost daily and love it. In fact I go out of my way to find places to engage and use it.
My advice to the OP is to take his car to his local Volt certified dealer and have it looked at.

1. There is a gap setting.
2. Like standard CC, brakes turn ACC off. In Volt, regen paddle also turns it off.
3. The operation is like riding with a teen driver. Very reactive instead of situational awareness.
4. Wash the dang car.
5. Environmental conditions can fool the sensors. Fog, rain, snow, sunlight, reflections at night, bumpy road, etc can all affect operation.
6. Stopped cars ARE NOT detected.
7. On curved or hilly roads, the camera and radar still point straight ahead.
8. Cars leaving or entering the lane are not detected immediately.
I use ACC every day. It is a rather large learning curve to use it in city traffic. I also drive in 'L' exclusively. For me, ACC seems to brake more smoothly in 'L'.
