The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM N25-F172AE a recall?
No. A over-the-air update is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the N25-F172AE repair free?
A over-the-air update is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does N25-F172AE cover?
The manufacturer filed it against 24 model years across 4 brands (Chevrolet, GMC, Buick and Cadillac): 2025 Buick Enclave, 2025 Buick Envision, 2024 Buick Envision, 2025 Cadillac Escalade, 2025 Cadillac Optiq, 2025 Cadillac XT4 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
