Front Suspension Control Arm problems of the 2009 Chevrolet Aveo

Update on problems with chevy Aveo 2009. After control arm, bearings,strut ,tires replaced in April,the car still has major creaking in the front end. Customer assistance and local dealer are both backing away from further help trying to get car fixed. Customer assistance says gm doesn't "owe" me a car to drive during repairs and his advice is to go to dealer and get repairs done," your warranty has expired". I now have a car with 21700 miles on it,that hasn't been fixed,and I am thinking probably can't be,due to mfg. ,design problems. What to do with a car like this,if it isn't recalled.

This is the third entry made trying to get the front end creaking noises from my car fixed by gm. Last week the dealer had my car from Tuesday until Friday and thought the noise had been fixed. Of course,when driven home,it was still there. The noise can only be heard at slow speeds,as in parking the car,or going over speed bumps. Strut and both bearings have been changed,also a control arm. I am afraid this is a design flaw that is unfixable,I have been trying since last summer,and the warranty is gone. Is it ever admitted that a car has been sold,new,that should not have been. This car has worn out a set of tires at 20000 miles,and they had been rotated regularly. Although,so far,gm has cooperated,I don't know how this is going to be resolved.
