Driving on the highway last night, and my stereo turns off and I realized my voltage was low, and then everything else started turning off. I eventually had no headlights or taillights. I got back home and I stopped in the parking lot, and checked the battery which is from this year. I had enough power to roll the windows up and down in the parking lot, and the stereo came back on but it had been reset. I'm worried that the tune I had on my car could have been reset and could it be on a stock tune?
