GM service campaign N252494770
What it saysAmendments to the Song-Beverly Act (SBA) California warranty law provides vehicle owners with an opportunity to submit a written notice to GM before filing a lawsuit seeking a vehicle repurchase. NHTSA’s full summary ↓
GM filed this with NHTSA as a service campaign dated Jun 17, 2025. It names 356 model years across Chevrolet, GMC, Buick, Cadillac, Brightdrop and Cruise (2018–2025). 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.

Vehicle owners of the applicable vehicles will be mailed an owner’s manual and warranty insert containing this information in English and Spanish.

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 295 model years this bulletin names have filed 29,220 complaints with NHTSA since 2015.
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.
Quote the number at the service desk. It is what the dealer’s system is keyed on.
Every manufacturer communication NHTSA holds for Chevrolet, GMC, Buick, Cadillac, Brightdrop and Cruise, by the number printed on the letter.
Common questions
Source: NHTSA, 49 CFR 579.5Is GM N252494770 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 N252494770 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 N252494770 cover?
The manufacturer filed it against 356 model years across 6 brands (Chevrolet, GMC, Buick, Cadillac, Brightdrop and Cruise): 2019 Buick Cascada, 2018 Buick Cascada, 2025 Buick Enclave, 2024 Buick Enclave, 2023 Buick Enclave, 2022 Buick Enclave and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
