I bought a 2007 Saturn ION Coupe the end of December 2006. I have had the car 4 mos and keep experiencing a wobbling when driving between 4-10 mph (traffic). They have balanced and aligned my car 4 times since I bought the car, once a month (it needs service every month I commute 1,000 mile a week). It seems to help for a short while and then the problem continues. Has anyone experienced this? They have checked everything, rotors, wheels, tires, etc. Any suggestions/answers?
