GMC bulletin N25-250380
GMC filed this with NHTSA as a over-the-air update dated Aug 7, 2025, received May 30, 2025, about the unknown or other — 3 documents under this number. It names 3 model years (2023–2025). A over-the-air update is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
