2001 LEXUS RX Power Train Problems

I BOUGHT A CAR FROM A PRIVATE PARTY/DEALER ONLY TO FIND OUT THAT REPAIRS NEEDED ARE MORE THAN CARS WORTH, THEN I CHECKED CAR FAX TO FIND OUT THAT MILEAGE HAD BEEN TURNED BACK A LOT.. THIS PERSON LISTS 3-4 CARS FOR SALE A WEEK AND I CAN'T FIND ANY ONE THAT WANTS TO HELP. I KNOW I AM STUCK WITH CAR UNFORTUNATELY IT WAS FOR MY HANDICAPPED SON THAT STARTED COLLEGE RECENTLY AND USED ALL HIS SAVINGS FOR CAR. I FOUND THAT THIS PERSON GOES UNDER SEVERAL NAMES AND ONLY LOCATION I HAVE IS WHERE I BOUGHT THE CAR. HIS HOME ADDRESS IS UNKNOWN AT THIS TIME. ATTEMPTS HAVE BEEN MADE TO CONTACT HIM WHERE I BOUGHT THE CAR BUT EVERY THING FAILED AND PERSON IS STILL SELLING CARS TODAY. I FORGOT I WAS SUPPOSE TO BUY A 2003 BUT TURNED OUT A 2001, IF YOU COULD DIRECT ME...

THE TRANSMISSION WAS REBUILT ON 11/15/13 AT 242,600 MILES AND HAS GONE OUT AGAIN AT 250,379. MANY OTHERS ON THE INTERNET HAVE HAD SIMILAR PROBLEMS WITH THEIR RX300 TRANSMISSIONS. MY BROTHER ALSO HAS AN RX300 AND HIS TRANSMISSION FAILED TOO. THE PLANETARY GEARS ARE OFTEN THE PROBLEM. THERE SHOULD BE A RECALL BY LEXUS TO DEAL WITH THIS DEFECTIVE DESIGN. *TR

TRANSMISSION FAILED AT A LOW MILAGE, AND THE REPAIR COST IS MORE THAN A CAR. *TR

I WAS JUST GETTING OFF THE HIGHWAY AND MY CAR STOPPED MOVING. MY TRANSMISSION TOTALLY WENT OUT WITH NO WARNING. IF THIS WOULD HAVE HAPPENED MOMENTS SOONER I COULD HAVE BEEN IN A TERRIBLE ACCIDENT AS I WAS GOING 60 MPH. I TRIED TO CONTACT LEXUS, BUT THEY WILL NOT ADMIT TO THIS PROBLEM OR HELP REPAIR IT OR RECALL IT. THEY SAY THAT IT ISN'T A KNOW ISSUE BUT IT IS AND SEVERAL PEOPLE HAVE TRIED TO GET HELP WITH IT AND LEXUS WILL SAY NO. BE CAREFUL, IT WILL HAPPEN WITH NO WARNING. *TR
