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

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 117 complaints with NHTSA since 2015. 24 of them name Engine — 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.
The contact owns a 2023 Buick Enclave. The contact stated that the vehicle was purchased brand new in May. The contact stated while driving 35 MPH, the message "Oil Needed" was displayed. The contact stated that she drove to her destination and then drove back to the residence. The vehicle was towed to the dealer to be diagnosed.

Vehicle shut down and stopped suddenly while driving. Twice this happened. Both times were under 20 miles per hour. Once at a railroad crossing and the other was turning onto a major roadway. Dealership can not locate the problem
2023 Chevrolet Traverse · Engine · filed with NHTSA Jul 25, 2024 · ODI 11604415
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 PIE0757A 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 PIE0757A 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. Every GM warranty extension on file lists the ones GM has filed.
Which vehicles does PIE0757A cover?
The manufacturer filed it against 2 model years across 2 brands (Chevrolet and Buick): 2023 Buick Enclave, 2023 Chevrolet Traverse. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
