One problem related to brake fluid has been reported for the 2003 Saturn ION. The most recently reported issues are listed below.
There is a leak in the c-line (the hose between the master cylinder and the slave cylinder. I talked to another Saturn owner and they have the same problem of the leaking hose. Since this fluid controls both my clutch and my brakes, this is a major problem.
