2011 CHEVROLET AVEO Tires Problems

12-1-12 PURCHASED VEHICLE FROM [XXX], THE VEHICLE HAD A SLIGHT PULL AND SALE PERSON SAID IT WAS JUST THE LOW TIRE. WHILE FILLING OUT PAPERWORK AND FINANCE DOCS VEHICLE WAS DETAILED AND TIRE WAS ADJUSTED. WE HAD THE FINANCE PEOPLE PUT AN EXTRA CLAUSE IN ABOUT THE TIRE AND THE ISSUE BEING FIXED. 1/3/13- CAR GOES IN BECAUSE OF IT PULLING AND TIRE LIGHT ON- THEY SAID IT WAS JUST BECAUSE THE DETAIL PERSON OVER FILLED ALL OF THE TIRES. BECAUSE OF MEDICAL SURGERIES I WAS UNABLE TO DRIVE THE CAR FROM TIME OF PURCHASE UNTIL JANUARY 29, 2013. I GAVE IT A MONTH JUST BECAUSE I WAS GOING FROM AN SUV TO THIS SMALL CAR AND I KEPT THINKING THAT IT WAS JUST THE DIFFERENCE IN CARS. THEN I DECIDED NO THERE IS SOMETHING WRONG WITH THIS CAR. 3/2/13 BACK TO [XXX] FOR PULLING AND WHISTLE NOISE. SHOP CROSS...
