Two problems related to suspension noise have been reported for the 2003 Saturn ION. The most recently reported issues are listed below.
Takata recall the seat belts when stopping suddenly do not always lock up. This is very dangerous especially with kids. The fuel system has been producing a check engine light at certain times of fueling up. And the fuel pump will knock occasionally even after it's been changed. The suspension is really bad and dangerous, rattling noise and shaking.
The car wont start and I changed the battery and had the alternator tested and starter both passed I attempt to start the car the ignition switch clicks then stalls, security system kicks in reads "service engine soon" after about 20minutes the car starts, hear rattling noise in front suspension this is happening all the time for the past year since I bought the car.
