Do not ever forget that these new fang dangled electronic devices are only aids to assist you, not for you to be totally reliant on them to stop you from having or causing an accident.It is such a signature system for them, and you aren't far out of warranty, so I would definitely talk to SoA.
Wouldn't be good for business (or us!) if these things started failing early and frequently.
Whenever I use the CC, my foot is very close to the brake and my thumb is hovering over the CC button on the steering wheel, just in case.
Personally, I think the cars of today have far too many electronic aids, LKA - Eyesight - ACC - Front and Rear parking sensors - Reversing Cameras etc., it just makes drivers less aware of their surroundings and what is going on in their vicinity.
Yes, I have reversing camera on my CRV but the only time I use it is to check my alignment when parking in a bay with lines, I trust it so much that I still visually check the alignment when I get out of the car. Outside of that I still use my eyes and the mirrors. The sunlight affects the cameras clarity too much for me to use it regularly.
