What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 22 complaints with NHTSA since 2015. 7 of them name Electrical System, Back Over Prevention — 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.
The entire left portion of the screen became inoperable and remained a black screen despite attempts to reset the system. The left side of the screen contains information such as gear selection, speedometer, lane keep assist, and many other important information. There is no other way to see what speed you are going besides this screen.

Backing out of driveway and screen went black and a collision occurred a second or two later. We have had the Lyriq in the shop multiple times for glitchy screens and screen going black but never has been fully resolved. I did recieve a recall letter (unfortunately I threw it away) but now it shows no recalls (strange).

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Cadillac N23-241765 a recall?
No. A service bulletin 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 N23-241765 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does N23-241765 cover?
The manufacturer filed it against 1 model year: 2023 Cadillac Lyriq. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
