Going down the interstate I hit the gas get to speed limit. 3 times the vehicle kept speeding up hitting 80 and still wanting to climb.when I hit breaks hit was hard to press worse then hitting non power breaks and then I forced on the brakes and the vehicle started shaking. And took lot of effort to slow down. This vehicle doesn't have cruise control. Have had cliche with lights radio tac speed air while driving.
