Kia filed this with NHTSA as a service campaign dated Apr 17, 2026, received May 1, 2026, about the power train — 7 documents under this number: SC363_TSB, SC363_OWNR_NQ5, SC363_OWNR_KA4, SC363_OWNR_DL3 and 3 more. It names 5 model years (2025–2026).

TECHNICAL SERVICE BULLETIN: VOLUNTARY SERVICE CAMPAIGN: OIL LEVEL PLUG (OLP) INSPECTION, AND OLP GASKET AND/OR ATF FILLER BOLT REPLACEMENT OR A/T REPLACEMENT (SC363) - This bulletin provides information to inspect the oil level plug and automatic transmission fluid (ATF) for signs of leakage and, if necessary, replace the oil level plug gasket and/or ATF filler bolt, or the 8-speed Automatic Transaxle (A/T) assembly on certain 2025-2026 Kia model vehicles listed in the table below. Also, dealers are to ensure the oil level plug is tightened to Kia’s factory specifications upon the completion of the inspection and necessary repair. The oil level plug in the subject vehicles may not have been installed properly during assembly. The oil level plug may be loose or detached from the 8-speed Automatic Transaxle (A/T) which may result in leaking automatic transmission fluid (ATF). A transaxle which is operated with excessively low ATF may become damaged over time.

Read by machine from the document NHTSA serves (8 pages), read Sep 30, 2026. A part number is shown only where it matches Kia’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote.
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 5 model years this bulletin names have filed 363 complaints with NHTSA since 2015. 36 of them name Power Train — 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.
Detailed information is in the attached pdf file, but in a nutshell, Kia is covering a safety defect in their vehicles by claiming the process is “proprietary”. On several occasions we have lost propulsion, which means we had no control over our vehicle, and Kia’s explanation is simply, “the vehicle is performing as intended “!
2026 Kia Carnival · Power Train · filed with NHTSA Aug 7, 2026 · ODI 11755434
The K5 - as soon as I began driving it at 0 miles, I noticed it shifted at lower speeds extremely hard. Head-jerking hard during the first drive of each day at speeds below 25mph. Once the vehicle warmed up, the problem would go away and wouldn't appear until the next day - after the vehicle cooled down completely.

The shifter would indicate it's in neutral but the car would think it's in drive. The car was immobilized and could not be moved when hitting the accelerator. This happened in the middle of Baltimore. I had to 'reboot' the car to get it to work, 3-4 times, while sitting in traffic.

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 SC363 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 SC363 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 SC363 cover?
The manufacturer filed it against 5 model years: 2026 Kia Carnival, 2025 Kia Carnival, 2026 Kia K5, 2025 Kia K5, 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: K5 (DL3): built 7 Apr 2025 – 1 Oct 2025; Sportage (NQ5a): built 11 Jun 2025 – 19 Aug 2025; Carnival (KA4): built 20 Feb 2025 – 17 Sep 2025 — the build date is on the certification label in the driver’s door jamb.
