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.

What owners reported
Source: NHTSA complaint databaseOwners of the 7 model years this bulletin names have filed 235 complaints with NHTSA since 2015. 7 of them name Fuel/Propulsion System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
My car is equipped with a forward-facing camera, mounted on the forward area of the interior rearview mirror. Additional cameras are mounted on the front bumper, trunk door, and on the rearview mirrors on each side of the car. Various sensors mounted throughout both bumpers face the front, rear, and each side of the car.

Common questions
Source: NHTSA, 49 CFR 579.5Is Cadillac 661.40 a recall?

Is the 661.40 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 661.40 cover?
The manufacturer filed it against 7 model years: 2025 Cadillac Celestiq, 2026 Cadillac Escalade, 2025 Cadillac Escalade, 2026 Cadillac Lyriq, 2025 Cadillac Lyriq, 2024 Cadillac Lyriq and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
