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.

Is the 654.20 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 654.20 cover?
The manufacturer filed it against 8 model years: 2026 Cadillac Escalade, 2025 Cadillac Escalade, 2024 Cadillac Escalade, 2023 Cadillac Escalade, 2026 Cadillac Lyriq, 2023 Cadillac Lyriq and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
