2007 HYUNDAI AZERA Structurebody Problems

THE CARS LEAKING OIL INTO THE ALTERNATOR.THE OWNER BEFORE ME SAID THEY FIXED THE GASKET AND REPLACED THE ALTERNATOR TWICE.I BOUGHT IT 12/01/20 AND HAVENT DRIVEN IT DUE TO ITS COST TO FIX THE LEAK AND REPLACE THE ALTERNATOR. IF HE GAVE UP ON HIGHWAY GUARANTEE OF AN ACCIDENT. BACK DRIVER SIDE DOOR HANDLE FELL OFF. PASSENGER SIDE FRONT SEAT WON'T WORK

THE LEFT REAR DOOR OPENED WHILE DRIVING AS THE DOOR IS UNABLE TO BE CLOSED AND REMAIN CLOSED. THIS IS NOT A LOCKING PROBLEM AS THE DOOR WILL NOT STAY IN A CLOSED POSITION

WHILE SITTING IN A DRIVE THRU WINDOW AT A COMPLETE STOP, MY CAR EXPERIENCED SUDDEN UNINTENDED ACCELERATION AND CRASHED INTO THE STOP CAR IN FRONT OF ME. THE RATE AT WHICH MY CAR ACCELERATED WAS SO GREAT THAT I HAD WHIP LASH FROM THIS EVENT. I AM SCARED TO DRIVE MY CAR AGAIN. I CALLED HYUNDAI WHO ASSURED ME THAT THIS DID NOT HAPPEN AS I STATED AND THERE IS NOTHING WRONG WITH THEIR CARS. INTERESTINGLY, MY CAR HAD JUST BEEN AT THE DEALER(2 WEEKS) FOR A TSB ON "EMISSION CONTROL" ISSUE. MY CAR WAS SLUGGISH AND STALING WHEN I CAME TO A STOP. NOW 2 WEEKS LATER I AM SLAMMING INTO A STOPPED CAR AT WHAT SEEMED LIKE 60MPH!! PLEASE HELP ME. *TR

THE HARD PLASTIC UNDERCARRIAGE PANEL FELL DOWN TO THE PAVEMENT IN THE FRONT WHERE IT WAS ATTACHED CLOSE TO THE ENGINE BUT REMAINED ATTACHED AT THE REAR OF THE CAR. SO IT WAS SCRAPPING THE PAVEMENT AS THE CAR WAS MOVING ON AN EXPRESSWAY GOING 60 MPH AT THE TIME. IT WAS LUCKY FOR ME THAT IT DID NOT BREAK OFF AND HIT SOME OTHER MOTORIST. THE BOLTS THAT ATTACH IT TO THE CAR FAILED. I READ HYUNDAI FORUMS WHERE THIS HAS HAPPENED TO OTHER AZERA OWNERS. TOOK IT TO THE DEALER AND HAD A NEW UNDERCARRIAGE PANEL INSTALLED.
