What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 1,116 complaints with NHTSA since 2015. 192 of them name Fuel/Propulsion System, Electrical System — 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 Soul, the 24 owners who gave an odometer reading for Fuel/Propulsion System reported it at a median of 75,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
My car has had intermittent faults of codes P1B25 and P1CF2 and are showing check EV system on the dash. This happens after about 30-45 minutes of driving and then restarting the car. It has been identified that the power relay assembly needs to be replaced on the vehicle, which lives in the high voltage battery pack.

When accelerating from a complete stop the vehicle will not accelerate. Pressing the accelerator a little or a lot does not matter. The engine does not produce RPM and does not accelerate for around 3-5 seconds. There is not an engine light on. All other aspects of the vehicle work properly when this happens.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Is the SC310Z repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does SC310Z cover?
The manufacturer filed it against 2 model years: 2017 Kia Soul, 2016 Kia Soul. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
