Kia filed this with NHTSA as a service bulletin dated Oct 9, 2024, received Oct 23, 2024, about the structure — 2 documents under this number: CS2401_TSB, CS2401_OWNR. It names 1 model year (2025). 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 CS2401 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 CS2401 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 CS2401 cover?
The manufacturer filed it against 1 model year: 2025 Kia Carnival. 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: Carnival (KA4) EX, SX, SXP: built 16 Apr 2024 – 24 May 2024 — the build date is on the certification label in the driver’s door jamb.
