Cadillac bulletin N25-250179
Cadillac filed this with NHTSA as a over-the-air update dated Jun 17, 2025, received Jul 1, 2025, about the unknown or other — 2 documents under this number. It names 2 model years (2024–2025). 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.

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.
