Have a 2008 Optima, less than 2500 miles on it. Today I noticed that when my wife was sitting in the passenger seat, the dash light indicated "Passenger Air Bag OFF". I pulled over and restarted the car it and went off. I had a Chevy Aveo that had this EXACT same problem and the dealer could not/would not fix it. Incidentally, my wife is 5'6" and about 150 lbs. Anyone else out there with a 2008 Optima LX ever see this? I know it was a common problem with the Aveo - but again? On a Kia Optima LX? HELP!
