I noticed my driver's side headlight was out and wires attached to the headlight underneath the hood had burnt out. The next day the vehicle would not not start at all. I had it jumped off and had a diagnostic ran on the battery. I was told it was not the battery but the alternator. The next day, I decided to take the vehicle to a Chevrolet dealer so I had it jumped off again. Initially, both headlights came on and a minute later; both headlights went out. The dealer kept the car two days before telling me sockets melted, the battery would have to be replaced along with bulbs and wires. Never once did they mention that there was a problem with the 2002-2008 chevy Aveo electrical system. The dealer initially wanted to charge 1027. 42 and they said they had no idea how this problem had occurred. I only had 30,300 miles on the vehicle. The dealer later charged me 563. . 44 but they cut many corners. After some internet research, I discovered that these type of problems have occurred with the chevy Aveo for years! when I contacted gm, their response was that the 3 year warranty had expired so there wasn't much they could do. Gm didn't even mention the electrical system problem!.
