Service bulletin TSB_GEN099_R2

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

TECHNICAL 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 7. 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.
