Kia Motors will be contacting the owners of certain 2016 Kia Optima‘s, regarding a problem affecting the right front axle driveshaft. Insufficient welds at the wheel end of the shaft may result in driveshaft cracks. During acceleration from a stopped position, the crack could completely separate, resulting in a loud noise and loss of motive power. If the driver fails to engage the parking brake under these conditions the vehicle could unexpectedly roll away.

Those receiving notices will be asked to return to their dealers to have the front axle driveshaft replaced. For more information about the problem, owners are asked to contact Kia customer service at 1-800-333-4542. Kia’s number for this recall is SC139 and the NHTSA campaign number is 16V-705.
