What it saysThis technical bulletin provides repair information to correct a customer concern of UDV Cluster Software version 162.3. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Jan 31, 2024, received Jul 14, 2023, about the equipment — 2 documents under this number. It names 10 model years across Chevrolet and GMC (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 (7 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 10 model years this bulletin names have filed 3,696 complaints with NHTSA since 2015. 586 of them name Electrical System — 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.
On the 2022 Chevrolet Silverado, the 14 owners who gave an odometer reading for Electrical System reported it at a median of 51,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Electrical component- Dashboard is constantly glitching, blue-tooth will not connect properly, electrical appears to turn off randomly while driving to the point we have to pullover because it appears and feels like the truck is turning off. Power step running boards malfunction- They don't open or close when they are supposed to.

I've had my 2023 Tahoe for 15 months, purchased Dec. 2023 Issue #1. Dash message on start up " Restraint System Needs Service". I noticed small lights overhead (buttons for tail gate, sun roof, reading lamps) were off. I pressed some of them, and dash message went away, and lights came on. Everything worked fine.

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-070 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-070 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-070 cover?
The manufacturer filed it against 10 model years across 2 brands (Chevrolet and GMC): 2023 Chevrolet Silverado, 2022 Chevrolet Silverado, 2023 Chevrolet Suburban, 2022 Chevrolet Suburban, 2023 Chevrolet Tahoe, 2022 Chevrolet Tahoe and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
