I wasn't aware that this was a feature of the gas models as well. I noticed this when I first test drove the diesel.Car drops into neutral at a stop as a fuel saving feature. You're feeling the transition back into gear.
You can put in manual mode when coming to a stop (won't go into neutral) or just learn to ease on to the gas gingerly.
That drove me nuts with a rental Cruze in DC traffic. If you slow down and then get on the gas again, even lightly, it's horribly confused.Maybe it's my driving habits, (I do drive 2-footed.), but I rarely experience the problem. Usually it occurs when I'm slowing down and then suddenly get on the gas. I end up surprising the transmission.
