Radio/tape Cd Player problems of the 2004 Saturn ION

I purchase a 2004 Saturn Ion (6/11/04), brand new. The first sign of cold that year, late November, the car would not start at all. After awhile(10-15 min. ) it would start up like nothing was wrong. I brought it in 12/28/04, which they replaced the ignition lock module; saying "that was the problem". I still had issues with the car through the winter, and they didn't know was what wrong. Everytime I brought it in, they would find nothing wrong and send me on my way since they couldn't reproduce the issue. The next winter than same thing happened. I was stuck in the cold a few mornings before work trying to get the car started. Saturn claimed it was too cold outside for my car to start, and told me to wait a bit before bringing it in. (it maybe went below 0 degrees that week twice) fed up I brought it in again on 1/17/05, which they replaced my block assembly, wire harness, starter, battery, and wire connecters. They really weren't sure what was wrong they admitted, but it seems to work now. The car would work for a few weeks, then the same issue arises again. On 4/15/05 Saturn had to replace my radio receiver for faulty issues. That same winter, my car would not start in the cold again. It was brought in on 12/20/05, which they replaced my ignition switch saying the usual "this will fix the problem". Now, just under two years later, I am back to having the same issues of my car not starting in the cold. Saturn is now throwing their hands up saying I must purchase another ignition switch, and pay them to put it in for a total of $220. Unacceptable. I may have taken actions sooner, but I wasn't aware there were many more Saturn Ion drivers with the same issues I had.
