looks like they have the window problem on the radar to fix. As far as the sputtering it's fairly rare but the stopping is rough and it downshifts into the first gear early. Choppy stops 40 percent of the time. Also when it's warmed up and you hold it at 2500 rpm the vehicle shakes sometimes then other times it's perfectly fine and smooth. Is this early warning for the pump that others have experienced? Taking it in for 2nd time next week.
