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! I've currently spent over $2000 alone in repairs on the suspension, rack and pinion & oil leak & manifold intake issues since purchase in 2019. Besides the check engine light turning on and off, there was no prior warning of the subframe and/or it's bolts being rusted out prior to purchase or prior to mechanics telling me about this dangerous repair needing done. Why is the 2001-2004 XG350 have recalls on this but not the 2005 year model that is exactly the same specs and materials used as the 2004????????????????????

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 TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE CRADLE THAT SUPPORTED THE ENGINE WAS RUSTED AND ROTTED OUT. THE TECHNICIAN ALSO STATED THAT THE AIR CONDITIONING DRAINING PIPE DRAINED INTO THE CRADLE, CAUSING THE CRADLE TO RUST. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 86,317.

I WAS BRAKING MY CAR AT THE END OF MY WORK'S DRIVEWAY WHICH ENTERS INTO A "T" INTERSECTION. 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 BUMPER OF CARS STOPPED IN FRONT OF ME WHILE I WAS BREAKING AND THE ENGINE WAS SURGING. SO VERY UNSAFE!! I CHECKED ON CARCOMPLAINTS.COM AND SAW 30 PLUS COMPLAINTS OF THE SAME NATURE. I WAS TOLD THE OLDER CARS HAD A ENGINE IDLER CONTROL TO KEEP THE ENGINE FROM STALLING AFTER BREAKING FROM HIGHER RPM'S TO NEAR 0 RPM'S. IS THIS NOW CONTROLLED WITH AN ELECTRONIC MODULE? I THINK THIS PROBLEM SHOULD CAUSE A RECALL FOR THIS PROBLEM. I DON'T WANT TO DRIVE THIS VEHICLE ANYMORE. EVERY TIME I BRAKE I DON'T KNOW IF I AM GOING TO INJURE SOMEONE!! *TR

SEVEN INSTANCES OF UNWANTED ENGINE ACCELERATION SINCE JAN 2006. ALL OCCURRENCES SIMILAR: 1)ENGINE IS WARM AFTER A PERIOD OF DRIVING; 2) CAR DECELERATING APPROACHING STOP SIGN, TRAFFIC LIGHT, OR IN STOP-AND-GO TRAFFIC; 3) A BARELY AUDIBLE "CLICK" IS HEARD AND THE ENGINE RPM BEGINS TO REV UP MAKING BRAKING DIFFICULT AND GIVING A CLUE THAT SOMETHING IS AMISS. WHEN THIS POINT IS REACHED KEY WAS TURNED OFF OR IDLE SELECTED TO SEE HOW HIGH THE RPM WOULD REV; 4800 IS THE HIGHEST NOTED. THIS IS A RANDOM EVENT AS THE CAR HAS OVER 10000 MILES WITH 7 OCCURRENCES. LATEST DATE IS NOTED BELOW. *JB
