The battery died in my 2009 kia Optima and upon replacing battery the airbag light came on. It was taken to a kia dealership and was told that it was because we changed the battery. The airbag light was reset. About a week later it came on again and was taken back to the dealership and reset again. It came back on the next day and was again taken to the dealership at what time we were told that it was the b1382 & b1481 airbag problems and that it was going to cost over $1200. 00 to fix. Why would changing the battery cause these problems? I had only purchased the car 18 months before this incident.
