In snow of almost any depth, the vehicle will shake violently on acceleration from 35 mph up. the transmission will not accelerate and feels like its bogging down. it will stay like this for sometime hours then it will cease. fender wells are clear of debris. the problem is it will do this sometimes at will on the roadway where i have been almost rear ended trying to get up to speed, there are multiple complaints on the chevy traverse forum website. someone is going to get seriously hurt or die. *tr
