EXTERIOR LIGHTING:TURN SIGNAL
What Happened
The Smart Junction Box in your Sedona is a computer that helps your turn signals work. In some 2015-2017 models, the software might get confused and send the wrong signal.
Risk if Unfixed
If this happens, your turn signal might flash the wrong way, which could cause confusion for other drivers and increase the risk of a crash.
Free Fix
Your Kia dealer will update the SJB software for free. You should contact them to schedule the update as soon as possible, and they'll take care of it at no cost to you.
