Chrysler Pt Cruiser possessed, please help

Okay, the memory was flashed last year. I took the time to write everything down that I could remember for symptoms and what has been repaired or replaced within the last couple of years. I took it to another dealership, after about a day of diagnosis, they said that it was the ignition switch. So far they have my car for 3 days and said it would be ready this afternoon. But why do I not feel assured that the problem is corrected?
