2005 Santa Fe 3.5 bucks when cruise control disengaged at all speeds. Dealer ordered parts corrected problem at speeds under 60 by replacing body assembly throttle and gasket throttle B. still bucks at speeds over 60 mph whether hitting brake or cancel button to disengage cruise. District service manager says all Santa Fe 3.5's do this they are designed with the electronic control throttle. Bucking of car is so pronounced every one in the car feels it. I will never feel safe in this vehicle using the cruise over 60 and will never use it when other people are in the vehicle. Just because it was designed this way and they all do it does not make it right. I feel this is a severe safety issue with this model. I was told only the 3.5's buck when the cruise is disengaged.
