What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationTECHNICAL SERVICE BULLETIN: CUSTOMER SATISFACTION: THEFT DETERRENT IGNITION CYLINDER PROTECTOR & DECAL INSTALLATION (CS2311) - This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides information to install a Theft Deterrent Ignition Cylinder Protector on certain 2010-2022MY Kia vehicles outlined on page 15, which may not have been equipped with an immobilizer and whose Integrated Body Control Unit (IBU) / Body Control Module (BCM) are not able to receive the Anti-Theft Software Logic upgrade under CS2301/02/03/04/05/06/07/08/09 TSBs. In an effort to help prevent thefts of Kia vehicles that are not equipped with an immobilizer, a protective cover will be permanently affixed to the ignition cylinder. This Theft Deterrent Ignition Cylinder Protector prevents the removal of the key lock cylinder thereby preventing access to the ignition tumbler.

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 16 model years this bulletin names have filed 2,988 complaints with NHTSA since 2015. 316 of them name Electrical System, Steering — 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.
On the 2017 Kia Forte, the 21 owners who gave an odometer reading for Electrical System reported it at a median of 32,850 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia CS2311 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 CS2311 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 CS2311 cover?
The manufacturer filed it against 16 model years: 2017 Kia Forte, 2016 Kia Forte, 2021 Kia Rio, 2020 Kia Rio, 2019 Kia Rio, 2018 Kia Rio and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
