GM filed this with NHTSA as a service bulletin dated Aug 17, 2023, received Sep 18, 2023, about the electrical system. It names 5 model years across Chevrolet, GMC 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 1,234 complaints with NHTSA since 2015. 166 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.
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.

I have had this vehicle serviced twice for the electrical issue on the running boards. While driving and while parked the running boards constantly deploy and store on their own or get stuck at a half way position. This will happen even if I have them turned off or on

Common questions
Source: NHTSA, 49 CFR 579.5Is GM PIT6049 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 PIT6049 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 PIT6049 cover?
The manufacturer filed it against 5 model years across 3 brands (Chevrolet, GMC and Cadillac): 2023 Cadillac Escalade, 2022 Cadillac Escalade, 2023 Chevrolet Suburban, 2023 Chevrolet Tahoe, 2023 GMC Yukon. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
