Chevrolet filed this with NHTSA as a service bulletin dated Mar 12, 2025, received Apr 14, 2025, about the electrical system. It names 2 model years (2025).

Read by machine from the document NHTSA serves (3 pages), read Sep 30, 2026. A part number is shown only where it matches Chevrolet’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.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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.

NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
What component or system failed or malfunctioned, and is it available for inspection upon request? On September 12, 2026, while parked at the top level of a parking garage, the vehicle unexpectedly began rolling forward after being parked and exited. The vehicle subsequently struck a concrete wall.

Common questions
Source: NHTSA, 49 CFR 579.5Is Chevrolet 25-NA-051 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 25-NA-051 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 25-NA-051 cover?
The manufacturer filed it against 2 model years: 2025 Chevrolet Blazer, 2025 Chevrolet Equinox. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
