2013 Kia Optima Hybrid Start issues
Replaced battery and worked fine for a week.
Jumped started fine and drives fine but when I
shut off it won't start back. Key fob inop and
steering wheel light is all that is showing on dash
Have you tested the alternator?
Try this first: Plug the keyfob into the slot for it inside the glove box. If it starts, then it could be the coin cell in the keyfob went dead. Easy fix, (new keyfob battery). Could also be the HSG Hybrid Started Generator, the wiring harness, or a loose ground connection. In these cars, the 12v battery is charged through the hybrid traction system (270v) battery.
