Sometimes the car will seem to downshift too early or too much (i.e. down to 1st when it should go to 2nd) when coming to a stop. It's most noticeable when either coasting slowly up to a stop with either none or very light brakes. Around 15 - 20mph sometimes it seems like the car throws out a boat anchor and very rapidly slows down to about 3-4mph. Today I was slowly coasting up to a red light and the car slowed to a crawl too soon, literally about the speed of a 90 year old woman with arthritis and a walker.
It doesn't always do this, and I never notice it under moderate to heavy braking. This is typically in comfort mode. In eco it tends to behave a bit better although I almost never shift to eco mode unless I'm in heavy stop and go. And the only reason I shift to eco mode then is to avoid getting seasick from the aforementioned tranny behavior.

I can't think of any good reason for a car in motion to engage first gear, but I'm almost sure mine occasionally does it in certain low speed conditions, like trolling around a parking lot.
