Official summary
Certain IONIQ 9 (ME1A EV) vehicles may exhibit adhesive residue on the high mounted stop lamp. This can occur when the clear protective film has had prolonged exposure to sun and heat, causing some of the adhesive to remain on the black plastic housing after removal. Technical Service Bulletin (TSB) 26-01-001H provides instructions to inspect and, if necessary, replace the high mounted stop lamp on affected vehicles.
Vehicles covered
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.
