GM filed this with NHTSA as a service bulletin dated Aug 21, 2023, received Sep 18, 2023, about the electronic stability control. It names 64 model years across Chevrolet, GMC, Buick and Cadillac (2021–2023).

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

NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The contact owns a 2023 Chevrolet Traverse. The contact stated while driving at approximately 70 MPH, the "ESC" message displayed, and the vehicle lost motive power and stalled. The contact stated that the vehicle failed to immediately restart.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM PIT6050 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 PIT6050 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 PIT6050 cover?
The manufacturer filed it against 64 model years across 4 brands (Chevrolet, GMC, Buick and Cadillac): 2023 Buick Enclave, 2022 Buick Enclave, 2023 Buick Encore, 2022 Buick Encore, 2021 Buick Encore, 2023 Buick Envision and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
