Kia filed this with NHTSA as a service bulletin dated Oct 15, 2025, received Sep 23, 2025, about the electrical system — 2 documents under this number: TSB_ELE400_CLSD, TSB_ELE400. It names 1 model year (2026). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

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: SERVICE ACTION: PDW OPERATION LOGIC IMPROVEMENT (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, as listed in the table below. In some cases, intermittent normal operation of the Parking Detection Warning (PDW) feature may occur due to unstable communication between the BDC and peripheral Integrated Circuits (IC). The upgrade addresses this issue by improving signal integrity and reducing the likelihood of communication disruptions.

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 1 model year this bulletin names have filed 43 complaints with NHTSA since 2015. 10 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia SA629 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 SA629 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 SA629 cover?
The manufacturer filed it against 1 model year: 2026 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: Sportage (NQ5a): built 18 Mar 2025 – 11 Sep 2025; Sportage (NQ5 P/HEV): built 23 Jun 2025 – 15 Aug 2025 — the build date is on the certification label in the driver’s door jamb.
