Mine is a manual. iGT hatch. Yes, Colonial.
About 5 days old, 300 miles. It hesitates not all the time, but on occasion, and only from a stop into first gear. Part of it is probably just getting a feel for how it gears. Coming from an 09 Fit which has a very different box (but oddly started to develop a similar issue). Another thing to consider is that I've had the AC cranked almost every day I've had it, since the weather has been icky sticky here in the NE (man, that was a long Spring -- gonna be a short summer).
I guess you could call it "lag." Again, it's intermittent, but when it happens, yeah, I'll swap the clutch for the gas, and it seem like there's a split second that passes before any _real_ response. It responds, but not like I want it to. I don't think I could get the tires to chirp, for instance.
It would be interesting to get together to compare rides. If I could see a noticeable difference, I'd have something concrete to take to the service dept.
