NHTSA Complaint #10713795 — 2013 HYUNDAI ELANTRA

I RECENTLY PURCHASED THIS VEHICLE USED AT A DEALERSHIP. AS I WAS DRIVING TO WORK ON THE INTERSTATE I RAN OVER A PART OF THE INTERSTATE THAT WAS POT HOLES BUT FILLED IN. AS I RAN OVER THE AREA, MY BACK END STARTED TO FISH TAIL. I TOOK THE CAR BACK TO THE DEALERSHIP ON 04/18/2015 AND I WAS TOLD THAT THE TIRE PRESSURE WAS WRONG AND THAT I NEEDED TO BE AWARE THAT MY CAR WAS CONSIDERED A SPORTS CAR AND IT WOULD HANDLE DIFFERENTLY THAN A REGULAR CAR AND THE BACK END BEING "LOOSE" WAS NORMAL. THE TIRE PRESSURE WAS ADJUSTED BUT I AM STILL HAVING THE SAME PROBLEM ALTHOUGH NOT AS BAD AND IT IS ONLY ON CERTAIN "BUMPS" IN THE ROAD THAT THE VEHICLE TRIES TO FISH TAIL.
