Kia bulletin SA556
Kia filed this with NHTSA as a service bulletin dated Oct 22, 2025, received Sep 17, 2024, about the wheels — 2 documents under this number: TSB_GEN099_R3, TSB_GEN099_R2. It names 6 model years (2023–2024). 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: SERVICE ACTION: TIRE MOBILITY KIT INSPECTION & REPLACEMENT/ REPAIR (SA556) - 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 inspect, and if necessary, replace the Tire Mobility Kit (TMK) sealant can or sealant can cap on certain 2023-2024MY Kia vehicles listed on page 5. Lower ambient temperatures can create a vacuum effect inside the TMK sealant can, causing the sealant can cap to open, resulting in the tire sealant leaking.

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 SA556 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 SA556 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 SA556 cover?
The manufacturer filed it against 6 model years: 2024 Kia EV6, 2023 Kia EV6, 2024 Kia Forte, 2023 Kia Forte, 2024 Kia Niro, 2023 Kia Niro. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
