One problem related to front suspension hub has been reported for the 2007 Saturn ION. The most recently reported issues are listed below.
Was hearing a popping,clicking, and rubbing sound and took to Saturn the first time they said it was my hub cap making the noise. I went back about an hour later and had them remove my hub cap and noise was even worse and you could feel it under you feet. They said it was my half shaft on the left side so a week later they replaced it. That was on a Friday and by Monday morning I was hearing and feeling the noise again so I took it back and they said that nothing was wrong with it but that I had a bent rim in the rear. I left but then thought about it and knew that was not right so I went back yet again and they looked at it and you could see where my tires and rims are grinding into and starting to cut my tie rod on the right but that was "normal" knowing it wasn't I proceeded to go to a 3rd party shop and pay out of pocket for them to look at the whole car. To no surprise to me that isn't "normal" and if not fixed soon will cause safety issues. The 3rd party also noticed what Saturn did not and that on my left side it is rubbing on not just the tie rod but the control arm as well. 3rd party told me that I have nothing there to prevent me from over turning my wheels and that is why I am having these problems. But only after contacting the bbb in colorado springs did the gm of Saturn of colorado springs want to listen to me. I have serious concerns about my safety and my sons safety in this vehicle. Please help.
