What owners reported
Source: NHTSA complaint databaseOwners of the 62 model years this bulletin names have filed 10,982 complaints with NHTSA since 2015. 1,561 of them name Electrical System, Forward Collision Avoidance — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2016 Kia Optima, the 37 owners who gave an odometer reading for Electrical System reported it at a median of 66,500 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia PS704 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the PS704 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Kia warranty extension on file lists the ones Kia has filed.
Which vehicles does PS704 cover?
The manufacturer filed it against 65 model years: 2020 Kia Cadenza, 2019 Kia Cadenza, 2018 Kia Cadenza, 2017 Kia Cadenza, 2016 Kia Cadenza, 2022 Kia Carnival and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
