Defect

Kia Motors America (Kia) is recalling certain model year 2016 Kia Optima vehicles manufactured November 13, 2015, to April 23, 2016 and equipped with a 2.4l engine. The right front axle driveshaft may crack and fail.

Consequence

If the driveshaft cracks and separates from the vehicle, it will not be able to move forward. Additionally, if the parking brake is not applied upon exiting the vehicle, the vehicle may roll. Either scenario can increase the risk of a crash.

Kia will notify owners, and dealers will replace the front axle driveshaft, free of charge. The recall began November 2016. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC139.
