GM filed this with NHTSA as a service campaign dated Mar 3, 2026. It names 44 model years across Chevrolet, GMC, Cadillac and Brightdrop (2017–2027). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
One page for every brand it was filed under. Each brand’s bulletins: Chevrolet · GMC · Cadillac · Brightdrop.

Read by machine from the document NHTSA serves (4 pages), read Sep 30, 2026. A part number is shown only where it matches GM’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.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM N252541510 a recall?
No. A service campaign 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 N252541510 repair free?
A service campaign 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 N252541510 cover?
The manufacturer filed it against 44 model years across 4 brands (Chevrolet, GMC, Cadillac and Brightdrop): 2026 Cadillac Celestiq, 2025 Cadillac Celestiq, 2026 Cadillac Escalade, 2025 Cadillac Escalade, 2026 Cadillac Lyriq, 2025 Cadillac Lyriq and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
