GM bulletin 19-NA-037
What it saysThis technical bulletin provides repair information to correct a customer concern of no start, hard start with belt squeal, belt break, loss of power steering and/or power brake assist. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Feb 28, 2024, received Feb 8, 2023, about the engine — 2 documents under this number. It names 15 model years across Chevrolet and GMC (2018–2024). 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.

Read by machine from the document NHTSA serves (4 pages), read Sep 30, 2026. A part number is shown only where it matches GM’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM 19-NA-037 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 19-NA-037 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 19-NA-037 cover?
The manufacturer filed it against 15 model years across 2 brands (Chevrolet and GMC): 2022 Chevrolet Equinox, 2024 Chevrolet Express, 2023 Chevrolet Express, 2021 Chevrolet Express, 2020 Chevrolet Express, 2019 Chevrolet Express and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
