Kia bulletin TSB_FUE066_CLSD
Kia filed this with NHTSA as a service bulletin dated Jun 30, 2025, received Jul 1, 2025, about the fuel/propulsion system. It names 3 model years (2021–2023). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia TSB_FUE066_CLSD 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 TSB_FUE066_CLSD 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.
Which vehicles does TSB_FUE066_CLSD cover?
The manufacturer filed it against 3 model years: 2022 Kia Sorento, 2021 Kia Sorento, 2023 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 1 Jul 2021 – 10 Jun 2022; Sportage (NQ5): built 15 Dec 2021 – 20 Dec 2022; Sportage (NQ5a): built 12 Jan 2022 – 10 Jun 2022 — the build date is on the certification label in the driver’s door jamb.
