GM bulletin 23-NA-181
What it saysThis technical bulletin provides service information to correct a customer concern of Excessive Brake Pedal Travel and/or Vehicle Hard to Stop. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Oct 17, 2023, received Nov 15, 2023, about the service brakes. It names 7 model years across Chevrolet and GMC (2021–2023). 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 (2 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.
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.

What owners reported
Source: NHTSA complaint databaseOwners of the 7 model years this bulletin names have filed 212 complaints with NHTSA since 2015. 5 of them name Service Brakes — 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 2021 Chevrolet Express. The contact stated that while driving at an undisclosed speed, the vehicle started to pull to the left, prompting the contact to pull over to the shoulder off the roadway. After a visual inspection, the contact stated there was smoke coming from the driver's side front brakes.

I lease a 2022 Equinox. February 15, 2023 I was driving from the store and began to pull in my driveway. I live on a dirt, dead end road. I turned the steering wheel and there was no reaction. The car kept going straight. I put on the brakes and the car didn't stop or slow down.

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 23-NA-181 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 23-NA-181 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 23-NA-181 cover?
The manufacturer filed it against 7 model years across 2 brands (Chevrolet and GMC): 2022 Chevrolet Equinox, 2023 Chevrolet Express, 2022 Chevrolet Express, 2021 Chevrolet Express, 2023 GMC Savana, 2022 GMC Savana and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
