Shakes or Wobbles problem
2005 Saturn Ion 4 cyl Automatic 79000 miles
When I start to slow down or stop at a red light, the car starts shaking. When I am at a complete stop and the car is idling, it feels like it is about to stall out. It drives me crazy! Then when ever I go over a bump in the road (could be the smallest bump) my car makes this squeeky, rattling noise. After I shut the car off completely, a few minutes later all you hear is a knocking coming from the back of the car, almost like someone is locked in the trunk.
Can you please tell me what the problem is with this car! I just bought it last December (2008)
