What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
TECHNICAL SERVICE BULLETIN: VOLUNTARY SERVICE CAMPAIGN PDW OPERATION LOGIC IMPROVEMENT (SC350) - This bulletin SC350, superseded the previously released TSB ELE400/SA629. This bulletin provides instructions for upgrading the Body Domain Controller (BDC) system on select 2026MY Sportage (NQ5a) and Sportage P/HEV (NQ5 P/HEV) vehicles listed in the table below. Due to a communication fault within the Body Domain Controller (BDC) in the subject vehicles, the Parking Distance Warning (PDW) system may operate intermittently. As a result, the PDW system may not trigger warning sounds or display visual warning indications to nearby objects when the vehicle is stopped or driven at low speeds. The upgrade addresses this issue by improving signal integrity and reducing the likelihood of communication disruptions.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 118 complaints with NHTSA since 2015. 29 of them name 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.
COMPONENT: Shift-by-wire transmission selector / hybrid control system. The vehicle is available for inspection upon request. WHAT HAPPENED: Intermittently, after starting the vehicle, it will not engage Drive or Reverse. The selector input is accepted but the vehicle remains in Park/Neutral and does not move.
2026 Kia Sportage · Electrical System · filed with NHTSA Sep 10, 2026 · ODI 11763449
Navigation screen began blinking (glitching) and suddenly went black and would not come back on. Called the dealership and they said it was not a recall and that it was no longer covered under warranty. This problem has persisted intermittently and I am noticing a pattern.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia SC350 a recall?
No. A service campaign 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 SC350 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 SC350 cover?
The manufacturer filed it against 2 model years: 2026 Kia Sportage, 2025 Kia Sportage. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built 18 Mar 2025 – 11 Sep 2025; built 23 Jun 2025 – 2 Sep 2025 — the build date is on the certification label in the driver’s door jamb.
