2015-2017 Kia Sedona SC217 Turn Signal Misdirection
The Smart Junction Box (SJB) software logic may not properly interpret the signals received from the multifunction switch, which could cause the turn signal to activate in the opposite direction of what the driver intended.

Has to do with turn signal misdirection-- evidently the turn signal can flash left when you turn the switch to the right and vice versa. This website has an interesting read on the history of the recall.
What I find amusing is that Kia extended the warranty on multi-function switches for 15 years / unlimited miles (I received that letter in the mail over the summer) only to discover later that the problem actually lied in a logic box / microcontroller.
Which has me wondering if they extended the multi-function switch warranty in hopes of the NHTSA probe just going away. Or perhaps Kia/Hyundai has been embroiled in so many issues lately they had to do something. I'm pleased I get the recall and now have a warranty on my turn signal switch for the next 8-9 years in case it ever goes out.
Even for those that don't own one of these vehicle, I enjoyed reading the recall history which taught me a bit about the process.
