Kia service campaign DC26
Kia filed this with NHTSA as a service campaign dated Feb 10, 2026, received Jan 28, 2026, about the engine — 2 documents under this number: TSB_ENG261_R1, TSB_ENG261. It names 7 model years (2026). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia DC26 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 DC26 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 DC26 cover?
The manufacturer filed it against 7 model years: 2026 Kia Carnival, 2026 Kia K4, 2026 Kia K5, 2026 Kia Niro, 2026 Kia Seltos, 2026 Kia Sorento and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
