Kia bulletin CS2312
Kia filed this with NHTSA as a service bulletin dated Jun 8, 2026, received Dec 24, 2025, about the structure — 4 documents under this number: CS2312_TSB_R2, TSB_CS2312_R1, TSB_CS2312, CS2312_OWNR. It names 44 model years (2016–2022). 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.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationCUSTOMER SATISFACTION CAMPAIGN: OWNER NOTIFICATION (CS2312) - This document is the owner notification advising that Kia is conducting Customer Satisfaction Campaign. A software upgrade that addresses the social media theft method has been made available to owners of eligible Kia model vehicles free of charge at authorized Kia dealers since 2023. In addition to the anti-theft software, a new zinc-reinforced ignition cylinder protector hardware upgrade has been developed and can be installed at the ignition cylinder location to provide additional protection against the social media theft method. Because the subject Kia vehicles were not factory-equipped with an engine immobilizer and were previously eligible for the software upgrade, these vehicles are eligible until March 31, 2027, to have the ignition cylinder protector installed—if requested—at no cost through an authorized Kia dealership. (Mailing of these notifications to vehicle owners will be completed from December 17, 2025 through February 27, 2026)

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 CS2312 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 CS2312 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 CS2312 cover?
The manufacturer filed it against 44 model years: 2021 Kia Forte, 2020 Kia Forte, 2019 Kia Forte, 2018 Kia Forte, 2017 Kia Forte, 2016 Kia Forte and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
