Kia Troubleshooting Questions? Ask a Mechanic
Thank you for allowing me to help you with this concern today and am sorry to hear that this is happening. I will have to ask you a few questions so that I can get a better understanding as to what may be going on with your Optima.
The problem that we see of these Optimas are that the alternator starts to go in and out like you are seeing (the Discharge Warning light). Do you hear any unusual noises or squealing?
