Clicking/vibration in pedal in TACC, EAP

[UCIBtheG]

I've used EAP (mostly) and TACC less frequently, but this morning I noticed a clicking noise and vibration in the accelerator pedal with autosteer enabled in heavy stop and go traffic. It would only happen at about 10mph when decelerating, when you'd normally apply the friction brakes to come to a stop. I have never noticed this before. I tested with TACC, and it did the same, and taking over manually there was nothing abnormal. I'm just about due for my 6250 mile tire rotation, so maybe I'll take it to the Rocklin SC and have them take a look, but was wondering if anyone else has experienced something similar.
