2012 HYUNDAI ELANTRA TOURING Engine Problems

MY ISSUE IS WITH AUTOMAKER HYUNDAI AND A KNOWN MANUFACTURING DEFECT IN THE ENGINES OF SOME 2011-2013 HYUNDAI ELANTRA CARS. I OWN ONE OF THESE CARS. IT IS FOR MY DAUGHTER, 17, WHO PAID THE MAJORITY OF THE $7000 WITH HER OWN MONEY TO BUY THE CAR. SHE HAS PUT AROUND 6-7 THOUSAND MILES ON IT SINCE SHE BOUGHT IT AND DESPITE HAVING THE CAR LOOKED AT BY A MECHANIC PRIOR TO PURCHASE, THE ENGINE HAS DEVELOPED A TICKING/KNOCKING NOTICE. AFTER TAKING IT TO A LOCAL DEALER IN MILWAUKEE, AMAMTO HYUNDAI, THEY HAVE SAID THE ISSUE IS A BAD ROD BEARING AND THE ENGINE WILL HAVE TO BE REPLACED. THE COST IS IN EXCESS OF $4000 - MORE THAN HALF IF WHAT SHE PAID FOR THE CAR. I HAVE DONE SOME EXTENSIVE RESEARCH ON THE WEB OVER THE LAST 10-14 DAYS AND HAVE FOUND THIS PROBLEM IS A COMMON ISSUE...
