Official summary
Some 2023MY Elantra N (CN7 N) and 2023-2024MY Elantra Hybrid (CN7 HEV) vehicles may have sealant leakage in the Tire Mobility Kit (TMK). The leakage may contaminate other parts inside or outside of the TMK bag. Follow the procedure in this bulletin to determine if the sealant is leaking and, if necessary, replace any parts that have been contaminated. If the sealant has not leaked, replace only the TMK Sealant Cap.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
