I think my Pilot is really smooth but I am comparing it to a 2014 Accord V6 with 6spd Auto that can be a bit jerky especially in its automatic downshifts. I think I know what you're talking about on the Pilot. To me it is still very smooth but sometimes just starting out there may be a little hesitation for a microsecond and then it feels like it catches and then maybe a little surge. I dunno. To me it is smooth but it's not like electric-motor smooth perfectly linear.
