One problem related to turn signal switch has been reported for the 2003 Saturn ION. The most recently reported issues are listed below.
I have had repeated problems with the exterior front lighting on my new 2003 Saturn Ion which is a safety hazard. On 5/15/03 I took the vehicle to the albuquerque Saturn dealership to fix the front driver side running light and left turn signal. They replaced the bulbs, but I had to take it to the dealership again on 7/18/03 after having driven it less than 100 miles for the same problem. This time they replaced the entire headlamp assembly. Then again on 9/29/03 I took it back to the dealership to have the passenger side front running light and turn signal replaced. I talked with the sales manager ben vigil and the service manager justin greenberg. I complained that I've spent more time at the dealership for unscheduled maintenance than routine maintenance, and I was concerned I had bought a lemon. I told them that if my turn signals aren't working properly, that is a safety issue. Mr. Greenberg told me that he probably gets two customers a day with the same problem (which shocked me). He said Saturn has sent out new bulbs to the dealerships which they claim will solve the problem. We'll see.
