The vehicle has a very bad shake when accelerating from a stop. It is very bad when turning while accelerating. The shake is worse when on a slight incline. Dealer service says it is normal! From others complaining of this issue, it appears to affect the Premium trim models with the Active Twin-Clutch System. I have had the Envision for a little over 2 months and am actively looking for something else, I can't stand it anymore.
