Kia bulletin TSB_CHA111
Kia filed this with NHTSA as a service bulletin dated Oct 6, 2021, received Oct 22, 2021, about the steering. It names 22 model years (2018–2021). 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 communicationTECHNICAL SERVICE BULLETIN: REPLACEMENT OF MOBIS C-MDPS SMALL BEARING - This bulletin provides the procedure to replace the small bearing of the Column Motor Driven Power Steering (C-MDPS) unit on the vehicles listed below, which may exhibit an abnormal noise when steering left and right. This may be caused by foreign substances in the MDPS worm shaft small bearing. On some vehicles when the steering wheel is rotated a scraping noise can be heard originating from the lower bearing on the Worm Gear Small Bearing and does not affect the steering effort.

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 TSB_CHA111 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_CHA111 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_CHA111 cover?
The manufacturer filed it against 22 model years: 2020 Kia Cadenza, 2019 Kia Cadenza, 2018 Kia Cadenza, 2021 Kia Forte, 2020 Kia Forte, 2019 Kia Forte and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
