GM filed this with NHTSA as a service campaign dated Aug 20, 2025, about the service brakes. It names 2 model years across Chevrolet and Buick (2024–2025). 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.

Read by machine from the document NHTSA serves (3 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 182 complaints with NHTSA since 2015. 78 of them name Service Brakes — 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.
This happens every single day, not just today, but are two separate issues related to my brakes. 1- squealing brakes. Every single day and for several miles before they warm up. The first time I brought this issue to the attention of the dealership, they replaced the brakes, and there was no squealing for just a few days.
2025 Buick Enclave · Service Brakes · filed with NHTSA Apr 5, 2026 · ODI 11729319
With less than 9,000 miles driven on the vehicle, the entire brake system failed as I was driving. I have since learned that there was a faulty master brake cylinder installed when the vehicle was built. No brake fluid was getting to any of the brakes.

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.
