I have a 2003 Saturn Ion and i also have the starting problem, where it wont start half the time and this really agatiates me really bad. Does anyone out there know why this happens, I think there should be a big recall on this

The problem is in the ignition - the grease gets thick in the cold and doent turn quite right the first time. everything turns on, but the anti theft system thinks you have the wrong key so shuts off pwer to the starter. it takes 8-10 mintues to reset. That is why it normally starts when you come back later. I have had the same problem and done tons of reseach. Right now my temp solution has been a small heater and an extention cord. I keep it plugged in over night on a medium setting - just enough to keep the inside temp above freezing. I am also researching remote starts because saturn dealership charges $250 to replace the ignition, and a remote start will run about $300. Saturn wont do a recall because they feel it is not a safety hazard. I say that is bull. Good luck!
