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.

What owners reported
Source: NHTSA complaint databaseOwners of the 12 model years this bulletin names have filed 971 complaints with NHTSA since 2015. 80 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.
I am writing to report a serious safety issue I experienced with my Chevrolet Camaro, which I believe may be related to a broader mechanical defect affecting General Motors vehicles. Approximately two weeks ago, while driving on the highway, an “ESC” (Electronic Stability Control) warning suddenly appeared on my dashboard.

My Corvette is a z06 that is designed and built for track use. When I use it on track it overheats and goes into limp mode after about 15 mins. Sometimes the power steer faults making it difficult and dangerous to control the car. I do not use it regularly on the street

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 Chevrolet 17-NA-408 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 17-NA-408 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 17-NA-408 cover?
The manufacturer filed it against 12 model years: 2024 Chevrolet Camaro, 2023 Chevrolet Camaro, 2022 Chevrolet Camaro, 2021 Chevrolet Camaro, 2020 Chevrolet Camaro, 2019 Chevrolet Camaro and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
