## What is wrong

Hyundai Motor America \(Hyundai\) is recalling certain 2015\-2017 Sonata, 2016\-2017 Sonata Hybrid, and Sonata Plug\-In Hybrid vehicles.  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.


## What can happen

A turn signal that activates in the opposite direction of what was intended by the driver increases the risk of a crash.


## The remedy

Dealers will update the SJB software, free of charge.  Owner notification letters were mailed November 19, 2021.  Owners may contact Hyundai customer service at 1\-855\-371\-9460.  Hyundai's number for this recall is 210.


## Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1\-888\-327\-4236 \(TTY 1\-800\-424\-9153\), or go to www.nhtsa.gov.
