GM bulletin N222371150-03
What it saysMessage sent to dealers to announce the final VINs were released. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Jun 5, 2023, about the steering. It names 8 model years across Chevrolet, GMC, Buick and Cadillac (2022–2023). 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 (1 page), 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 8 model years this bulletin names have filed 1,531 complaints with NHTSA since 2015. 5 of them name Steering — 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.
When I started my truck the Service Power Steering and Service ESC notifications came up on my panel. Now my truck has no power steering and it very difficult to steer and navigate. We are in the middle of a winter storm so it is even more of a safety issue in slippery conditions.
2022 GMC Sierra · Steering · filed with NHTSA Dec 15, 2022 · ODI 11497631
Stabiltrack software jerking my car in a left curve. Took to dealership who seem to find nothing wrong. Reached out to GM with no response or action. Feels extremely dangerous in a left curve unless traction control and Stabilitrack is turned off
2023 Buick Encore · Steering · filed with NHTSA Sep 22, 2026 · ODI 11766109
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 N222371150-03 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 N222371150-03 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 N222371150-03 cover?
The manufacturer filed it against 8 model years across 4 brands (Chevrolet, GMC, Buick and Cadillac): 2023 Buick Encore, 2022 Buick Encore, 2023 Cadillac XT4, 2022 Cadillac XT4, 2022 Chevrolet Silverado, 2023 Chevrolet Trailblazer and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
