l own a 2003 saturn ion and my coolant light just came on l checked the sensor and the floater and the car keeps sayin the same thing....also what is the major prob when the service vehicle light comes on...i just gave it a tune up like a week ago????......it has 110k miles on it is that good?

Good luck, l had a 2003 Saturn Ion Quad Coupe and had to put in three separate transmissions by 85,000 Miles. You might want to figure out what it is and get rid of that car as soon as possible.

well its not gonna last long, here is why:

It is a GM- car, very poorly built.
it has 110,000 miles on it. (be happy it lasted u that long)
