I recently noticed a  "click" noise whenever ACC  switch from the brake to accelerator. The click happens as soon as ACC relise pressure from the break pedal to start accelerating, at any given speed.  
When driving without ACC, no klick sound is heard when I press and relise break pedal. 
I drive a lot with cruise control and until now, no sound was ever made out of the pedals

Soo, nobody with the same “problem”?

so strange🤔

I didn't notice any such noise. 😞

I haven't noticed such a nosie either. Will keep an eye (or ear) for that next time. Is it coming from the pedal area?

Yes. Its more noticable when the car brakes harder and then try to accelerate.
