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 4 model years this bulletin names have filed 365 complaints with NHTSA since 2015. 8 of them name Structure — 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.
Passenger door failed to open three times since purchase. Tried locking/unlocking door from inside, outside and with key fob. Dealership looked at it in May 2026 and I reported it again because it happened two more times since.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia WTY043 a recall?
No. A warranty extension 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 WTY043 repair free?
A warranty extension 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 WTY043 cover?
The manufacturer filed it against 4 model years: 2026 Kia Sorento, 2025 Kia Sorento, 2024 Kia Sorento, 2023 Kia Sorento. 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: Sorento HEV (MQ4 HEV): built 27 Jun 2022 – 5 Dec 2025; Sorento PHEV (MQ4 PHEV): built 27 Jun 2022 – 22 Nov 2025 — the build date is on the certification label in the driver’s door jamb.
