One problem related to fuses and circuit breaker has been reported for the 2007 Saturn ION. The most recently reported issues are listed below.
I was on my honeymoon in orlando, FL. On Nov. 17th, 2011 when it went out the first time. I discovered that when I turned the vehicle off and started it again, that the power steering would return to proper operation. Since that day, it has been intermittent. No typical timing or environmental situation, just randomly stop working. It did that for several months until 3 weeks ago when it would shut off 5 minutes after starting the vehicle every time. Now, it does nothing, it never comes on. I checked both fuses and being in the vehicle industry myself, I know that a fuse, relay, or circuit breaker just dies. I feel that if it were the fuse, it would not only work sometimes but it would not work at all. I am expecting the manufacturer to replace this. As this is my 3rd Saturn and I had well over 200k on the other 2 with no problems at all.
