What it saysThis warranty bulletin provides information on Customer Concern Not Duplicated (CCND) Labor Operation Numbers. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Dec 14, 2024, received May 6, 2022, about the equipment — 5 documents under this number. It names 149 model years across Chevrolet, GMC, Buick and Cadillac (2019–2025). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.
One page for every brand it was filed under. Each brand’s bulletins: Chevrolet · GMC · Buick · Cadillac.

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 140 model years this bulletin names have filed 11,784 complaints with NHTSA since 2015. 5 of them name Equipment — 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 2025 GMC Sierra 3500 used for hauling a 2026 Aluminum Trailer equipped with a DeeMaxx: DBI-7K-MAXX-SS-KIT brake kit. The contact stated that while driving at an undisclosed speed, the brake caliper bracket detached due to insufficient generic quality bolts included in the brake kit.

The contact owns a 2024 Chevrolet Express 3500. The contact stated while the vehicle was parked, the contact noticed a huge black puddle of liquid on the ground on the front driver's side. The contact stated that upon inspection, it was determined that the unknown liquid was from the propane tank.
2024 Chevrolet Express · Equipment · filed with NHTSA Feb 10, 2025
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 22-NA-038 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-038 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-038 cover?
The manufacturer filed it against 149 model years across 4 brands (Chevrolet, GMC, Buick and Cadillac): 2025 Buick Enclave, 2024 Buick Enclave, 2023 Buick Enclave, 2022 Buick Enclave, 2025 Buick Encore, 2024 Buick Encore and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
