Spent about two hours today going to different places to try and figure out the problem. I started with Batteries Plus, who tested my battery and alternator and said everything looked fine (see picture below.) Afterwards I went to the dealership, who wouldn't tell me any possible problems but told me that they were going to charge me $140 just to see if there was one. Being a college student I decided to pass over that "great deal" and move on to my local repair shop who, after retesting my alternator, said they didn't know much about electronics. I've decided that I think I'm just going to let this ride out and see if any other issues show up or if it gets any worse. As I've said before, the problem is off and on, and it hasn't happened in the past two days. Crossing my fingers it was just a glitch.
