GM filed this with NHTSA as a service bulletin dated Sep 19, 2023, received Nov 2, 2022, about the service brakes — 2 documents under this number. It names 4 model years across Chevrolet and Buick (2022–2023).

Quoting the number at a service desk can save a diagnosis.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM 22-NA-097 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 22-NA-097 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 22-NA-097 cover?
The manufacturer filed it against 4 model years across 2 brands (Chevrolet and Buick): 2023 Buick Encore, 2022 Buick Encore, 2023 Chevrolet Trailblazer, 2022 Chevrolet Trailblazer. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
