2014 Hyundai Tucson complaints

I RECENTLY PURCHASED A 2014 HYUNDAI TUCSON GLS FROM MY LOCAL HYUNDAI DEALER. SHORTLY AFTER PURCHASING THE CAR, I NOTICED A STRONG VIBRATION THAT SEEMED TO COME FROM UNBALANCED TIRES. I TOOK THE CAR IN FOR THE FIRST TIME AND THEY FOUND IT WAS UNBALANCED AND PROCEEDED TO BALANCE THE CAR. HOWEVER, THIS DID NOT FIX THE PROBLEM. I STILL NOTICED A SLIGHT VIBRATION WHEN I DROVE THE CAR, AND IT WAS ESPECIALLY BAD AT 50MPH. I TOOK IT BACK FOR A SECOND TIME TO THE HYUNDAI DEALER AND THEY BALANCED THE CAR AGAIN, BUT ONLY A VERY SMALL AMOUNT. AGAIN, BALANCING THE TIRES MADE NO DIFFERENCE. I TOOK IT BACK TO THE DEALER FOR A THIRD TIME AND RODE IN THE CAR WITH THE LEAD MECHANIC AT THAT LOCATION. HE ALSO NOTICED THE VIBRATION AND ASKED I LEAVE THE CAR WITH HIM. HE THEN TESTED ONE OF THE OTHER TUCSONS ON THEIR LOT THAT WAS THE SAME TRIM MODEL AND HAD THE SAME TIRES. HE REQUESTED I GO WITH HIM IN THAT CAR, AND WE FELT THE SAME VIBRATION AS IN MY CAR. HE DIAGNOSED THE ISSUE AS A CHARACTERISTIC OF THE VEHICLE. ON COLD MORNINGS, THE CAR VIBRATES SO BADLY IT CHATTERS MY TEETH AND FEELS UNSAFE TO DRIVE. MY CONCERN IS THAT IT WILL ONLY CONTINUE GET WORSE WITH TIME, CAUSING PERMANENT DAMAGE. EVEN THOUGH THE CAR HAS A GREAT WARRANTY, I STILL FEEL UNCOMFORTABLE DRIVING IT AND AM RELUCTANT TO TAKE IT ON LONG TRIPS. I CURRENTLY HAVE A CASE OPEN WITH HYUNDAI MOTORS USA. THE CASE WAS OPENED IN MARCH OF 2014 AND HYUNDAI FEELS IT CAN BE SOLVED BY REPLACING THE TIRES. I HAVE NOT DONE THAT YET AS THEY WILL NO

DRIVING IN DRY CONDITIONS AND STEERING COMPLETELY FAILED. 2014 HYUNDAI TUCSON WITH 3200 MILES. BOUGHT BRAND NEW 3 MONTHS AGO IN MARCH 2014. *TR
