This morning, I couldn't start my car and charging system failure messages displayed. Lights and radio worked fine. I didn't spend too much time on it because I had to go to work. Once I got home from the work, the car started fine. I got the "System failure message" for the first time, but the message didn't come back after I shut off the car and start again. Bad battery? alternator?
