2016 Premier, a little over 3500 miles so far with no problems. Twice tonight I noticed a very subtle rumble while stopped at a light in EV mode. The engine was definitely not running, although the AC was running on the Eco setting. It felt very much like an ICE engine "missing" at idle. It happened briefly at one stoplight and I thought I might have imagined it (or that maybe there was a mild earthquake). But then a couple of minutes later the same thing at another light. Foot on the brake, no forward motion. Thoughts? Thanks.

It was probably the brake system hydraulic pump bringing up hydraulic pressure after you used the brakes.
