2005 Hyundai Sonata engine problems

ENGINE

My car's engine cradle, cross member or subframe is rusted out and the OEM replacement for my VIN number won't fit it correctly I'm getting really upset because this could be dangerous for me and my two young kids. I've already paid the mechanic $600 for the replacement part when it really only costs $450 at the most and the two he has ordered before have both been either too big and it says that it is the correct replacement part. What is going on?!!! If something isn't fixed soon and something happens to me or my kids there is going to be a lawsuit.

ENGINE

WHILE DRIVING ON THE FREEWAY THE CAR STARTED ACCELERATING ON ITS OWN. TRIED PUMPING THE GAS PEDAL TO RELEASE IT, CAR STILL ACCELERATED. BRAKES DID LITTLE GOOD. WAS ABLE TO DOWN SHIFT INTO FIRST GEAR, THEN INTO NEUTRAL AND UTILIZING THE EMERGENCY BRAKE WAS ABLE TO GET THE CAR SLOWED DOWN ENOUGH TO CUT THE ENGINE. SOME PROBLEM HAPPENED IMMEDIATELY WHEN I TURNED THE CAR BACK ON TRYING TO GET IT OFF THE FREEWAY OFF RAMP. WAS ABLE TO STOP SAFELY IN A PARKING LOT WITHOUT HITTING ANYTHING. HAD THE CAR TOWED TO THE DEALERSHIP, WHERE THEY SAID IT WAS A PROBLEM WITH THE THROTTLE.

WHILE DRIVING IN A HEAVY RAIN THE ENGINE BEGIN MISSING AND SLOWING DOWN. BECAUSE OF THE RAIN TRAFFIC WAS RUNNING AT ABOUT 25 MPH. THE ENGINE SHUT OFF AND I DRIFTED ONTO THE SHOULDER OF THE HIGHWAY (I 95). AFTER A FEW ATTEMPTS THE ENGINE RESTARTED , BUT WAS STILL MISSING BADLY I COULD ONLY GET TO APPROX. 20MPH. EACH TIME I STOPPED THE ENGINE WOULD STOP. USING THE SHOULDER OF THE ROAD WE WERE ABLE TO MAKE IT HOME. THE NEXT MORNING I TRIED TO START THE CAR BUT IT WOULD NOT. I OPEN THE HOOD JUST TO SEE IF THERE WAS ANYTHING VISIBLY WRONG. I CHECKED THE AIR FILTER AND FIND THAT IT WAS FULL OF WATER. WITH WET FILTER OUT AND THE WATER REMOVED FROM THE FILTER HOUSING THE CAR RUNS WITH OUT A PROBLEM. I CAN'T LOCATE WHERE THE AIR INTAKE IS TO SEE IF THERE IS PART MISSING ETC. THIS IS THE FOURTH TIME THIS HAS HAPPEN. THE DEALERS ANSWER FOR THIS PROBLEM "DON'T DRIVE IN HEAVY RAIN".

ENGINE AND ENGINE COOLING:ENGINE

I PURCHASED THE VEHICLE USED IN 12/2005 FROM A NON-HYUNDAI DEALER. I BEGAN TO NOTICE THAT THE CAR PERIODICALLY DID NOT SHUT OFF IMMEDIATELY WHEN THE KEY IS TURNED TO THE OFF POSITION. IT SHUDDERS FOR A FEW SECONDS, THEN GOES OFF. I HAVE CONTACTED THE MANUFACTURER AND HAVE BEEN TO THE HYUNDAI DEALER MORE THAN 3 TIMES WITH THIS COMPLAINT BEGINNING FEBRUARY/2006. I ALSO NOTICED THAT THE CAR VIBRATES/REVS UP WHEN AT A RED LIGHT. THIS IS VERY IRRITATING SINCE THE VIBRATION ALSO GOES THROUGH TO THE STEERING WHEEL AND CAUSES MY ARMS AND HANDS TO VIBRATE ALSO. INITIALLY, I WAS TOLD THAT ALL OF THIS WAS NORMAL - HOWEVER I DID NOT EXPERIENCE ANY OF THIS WHEN I RENTED THE SAME TYPE OF CAR LAST YEAR. THEN I WAS TOLD THAT THERE IS A LOOSE ENGINE MOUNT. I THEN HAD TWO EXPERIENCES WITHIN ONE WEEK WHERE THE CAR DID NOT START - LIGHTS, RADIO, A/C STILL CAME ON - BUT THE CAR DID NOT START. I HAD TO BE TOWED TO THE DEALERSHIP. THE FIRST TIME, THEY CHANGED A RELAY AND THE SECOND TIME, AFTER KEEPING THE CAR FOR ONE WEEK THEY CHANGED THE ENTIRE FUSE BOX. I HAVEN'T HAD A PROBLEM WITH THE CAR STARTING SINCE, HOWEVER THE VIBRATION IS GETTING WORSE, THE CAR STILL DOES NOT SHUT OFF IMMEDIATELY, AND NOW IT REVS TO THE POINT THAT THE CAR FEELS LIKE IT IS TRYING TO PULL OFF BEFORE I TAKE MY FOOT OFF OF THE BRAKE PEDAL. I PULLED A CAR HISTORY REPORT THAT REVEALED THAT THE CAR FAILED EMISSIONS, HAD A LEFT DOOR REPLACED, AND HAD A STARTER ASSEMBLY REPLACED. NONE OF THIS WAS DISCLOSED AT THE TIME OF PURCHASE AND WAS NOT INCLUDED ON THE CAR HISTORY REPORT PROVIDED BY THE SELLING DEALER - OTHERWISE, I WOULD HAVE NEVER PURCHASED THE VEHICLE. WHEN I QUESTIONED A RESIDUE BEHIND THE RADIO STATION DISPLAY PANEL, I WAS TOLD BY THE SELLING DEALER THAT IT COULD HAVE HAPPENED AS A RESULT OF THE AAA INSPECTION SINCE THEY SOMETIMES TAKE DOWN THE DASHBOARD.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE

BOUGHT 2005 HYUANDI ON 12/8/04. EXPERIENCED VIBRATION ON 12/9/05 TOOK CAR BACK TO DEALERSHIP IN CLEVELAND TENNESSEE, THEY SAID NOTHING WAS WRONG, BUT THEY THOUGHT THAT THE BOLTS THAT HOLD THE MOTOR IN CAR NEEDED TO BE TIGHTENED. TOOK CAR BACK 3 DAYS LATER FOR THE SAME PROBLEM VIBRATION, THEY SAID THAT THE BOLTS NEEDED TO BE TIGHTENED AGAIN. TOOK THE CAR BACK ON THREE OTHER OCCASIONS AND THEY CONTINUED TO TIGHTEN THE BOLTS THAT HOLD THE ENGINE IN THE CAR. FINALLY A REPRESENTATIVE WAS CALLED IN TO LOOK AT THE CAR HE HAD ME TO DRIVE THE CAR AND TOLD ME THAT IT WAS NORMAL FOR THE CAR TO HAVE A VIBRATION WHEN SITTING STILL AND THAT NOTHING WAS WRONG WITH THE CAR. ALSO, HE SAID THAT THE BOLTS NEEDED TO BE TIGHTENED THAT HOLD THE ENGINE IN.
