NHTSA Complaint #10420973 — 2010 HYUNDAI SANTA FE

MY 2010 AT SANTA FE STARTED WITH OCCASIONAL LURCHING FORWARD WHEN STARTED, THEN PROGRESSED TO HARSH SHIFTING, BUMPING AND BANGING NOISES FROM THE AT. THIS WAS EPISODIC, WHEN THE CAR WAS COLD. (SEE MY INITIAL COMPLAINT #10379504) SINCE MY ORIGINAL COMPLAINT, THE DEALER PUT IN A "DATA RECORDER" TO TRY TO CAPTURE WHAT WAS HAPPENING. DESPITE 2-3 EPISODES OF THIS HAPPENING WHILE THE RECORDER WAS ON, THEY WERE NOT CAPTURED ON THE UNIT. THEY TOLD ME THERE WAS NOTHING WRONG WITH THE CAR, YET IT CONTINUED TO GET PROGRESSIVELY WORSE. AT ABOUT 9000 MILES, IT HAPPENED AGAIN- THE WORST EPISODE YET. AT THAT POINT I WAS AFRAID FOR MY SAFETY. I DROVE THE CAR HOME AND THEN TO THE DEALER. AFTER THE DEALER DID FURTHER TESTING ON THE AT, THEY TOLD ME THERE WAS IN FACT SOMETHING WRONG WITH THE AT, AND THEY PUT IN A NEW TRANSMISSION. WITHIN 1000- 2000 MILES ON THE NEW TRANSMISSION, IN STARTED BUMPING AGAIN WHEN COLD, SHIFTING FROM 1ST TO 2ND. I TOOK IT BACK TO THE DEALER, BUT OF COURSE THEY CAN NOT DUPLICATE THE PROBLEM. THEY SAID IT HAD A FAST IDLE AND ADJUSTED IT. THEY ALSO SAID I SHOULD WARM THE CAR UP 5-7 MINUTES PRIOR TO DRIVING IT EACH TIME, SINCE I REPORT THIS ONLY OCCURS WHILE IT IS COLD. THEY SAY THERE IS NOTHING WRONG WITH MY CAR, JUST AS THEY TOLD ME EARLIER, PRIOR TO FINDING OUT THERE WAS A PROBLEM WITH THE AT. WHEN I LEFT THE DEALER AFTER TELLING ME THIS, IT BUMPED TWICE BEFORE I GOT OUT OF THEIR PARKING LOT, AND CONTINUES TO DO SO, ONCE EVEN WHILE IT WAS WARM. I CALLED HYUNDAI CONSUMER AFFAIRS, THEY PARROT BACK TO ME EVERYTHING THE DEALER TELLS ME, AND OFFER NO NEW SUGGESTIONS OTHER THAN TO CONSULT MY OWNERS MANUAL ON CONFLICT RESOLUTION. *TR
