Yes, the car runs great when it's actually running. The engine light is not on. The only thing I did notice is on Saturday (the day before it didn't start), I noticed the radio/cd player was fine as usual and the speakers had bass, later that day, I noticed the there was no bass and it sounded as if I may have blown the subwoofer or something in the speaker. Not sure if this has anything to do with it since the radio/cd player is a factory unit, not something that was installed after production. It's at the mechanics now and they can't seem to find anything wrong with the car. They told me they charged the battery and it appears to be holding the charge and the alternator is continuing to charge it. They asked if I may have left something on, but I hadn't. The interior light between the driver and passenger side seats was set to normal (only comes on when the doors are open). My mom seems to think that it could be due to the fact that I don't turn the radio/cd player off when I power the car off. However, that sounds ridiculous to me since I never turn the radio off when I shut the car off. I just turn the car off. Is this bad?
