Labour operations and the time the manufacturer allows

Read by machine from the document NHTSA serves (18 pages), read Sep 30, 2026. A part number is shown only where it matches Cadillac’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote.
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 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.
