2011 Kia Optima SX Turbo: Reflash Fixes Dash Lights
June 10, 2011
Well, they're working consistently now. I've been driving the Optima for a week now (OK, except for one day). More importantly, I've probably put more miles on this car than anyone and I'm yet to experience the problem.
If you've forgotten what it was...make the jump.
Dan Edmunds first reported the problem above here. He then fixed it by resetting the ECU (battery disconnect) here. Since then, however, we've had Kia reflash the ECU with a software update "representing the latest software version." Kia says the problem was due to an "error in the Body Control Module."
No problem since.
