In May 2021, the NHTSA made an inquiry to Kia North America after receiving complaints related to turn signal malfunctions in certain 2015-2017 Sedona vehicles. During the investigation, the 2017 Sportage was identified as using the same multi-function switch as the 2015-2017 Sedona, but had no similar complaints. Kia aslo determined that the 2017 Sportage has similar Smart Junction Box (SJB) logic as the 2015-2017 Sedona but was produced by a different supplier.
According to the defect report, under certain conditions the SJB software logic in certain 2015-2017 Sedona vehicles may not properly interpret the signals received from the multi-function switch . (Kia SJB software logic was improved during latter part of 2017 Sedona production.) As a result, the turn signal may intermittently activate in the opposite direction of what was intended by the driver.
Kia has decided to conduct safety recall to address turn signal misdirection issue. There have been 369 warranty claims, 44 customer complaints and 24 techline reports.
If this condition occurs, the unintended turn signal direction will be visible to the driver on the instrument cluster.
Owners receiving notices will be asked to return to their dealers to have the SJB software updated in their Sedona vehicle. Kia's number for this recall is SC217 and the NHTSA campaign number is 21V-725.
