2005 HYUNDAI XG350 Engine Problems

1) The vehicle idle is too high. It jerks forward every time I'm at a stop then I want to go forward. I have almost ran into the back of other cars while waiting at a stop sign. 2) The bolts and Subframe is coming detached from the car. It has been confirmed by dealership and franchise auto repair places (2 of them) that the car motor is knocking around and the subframe is loose!

TL* THE CONTACT OWNS A 2005 HYUNDAI XG350. WHILE DRIVING APPROXIMATELY 25 MPH, THE VEHICLE PULLED TO THE RIGHT AND IT WAS DIFFICULT TO KEEP THE WHEELS STRAIGHT. THE FAILURE OCCURRED WITHOUT WARNING.

THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 86,317.

UPON REACHING A SLOW SPEED OF 5 MPH THE CAR SURGED INTO THE TRAFFIC WHICH WAS TRAVELING FROM MY LEFT AND RIGHT. BRAKING FULLY HAD NO EFFECT ON THE SURGE AND THANKFULLY I WAS NOT HIT BY ANY LEFT OR RIGHT TRAVELING VEHICLES AND I JUST MISSED A VEHICLE CROSSING IN FRONT OF ME BY AN INCH AS IT PASSED. STILL BRAKING FULLY, MY CAR CROSSED THE ENTIRE ROAD AND JUMPED A CURB, SLIGHTLY HIT A RISING GRASSY HILL AND FINALLY CAME TO REST FULLY ON THE HILL ONLY AFTER I PUNCHED THE SHIFT INTO NEUTRAL. I SHOULD HAVE BEEN KILLED AND I COULD HAVE SERIOUSLY HURT THE INDIVIDUAL CROSSING IN FRONT OF ME. THIS HAS BEEN THE FOURTH INCIDENT OF THIS NATURE. THE FIRST THREE INVOLVED SOFT TAPS TO THE REAR...
