What it saysThis warranty administration bulletin provides information for dealers/technicians on System Reset and Connector Reconnect Labor Code Numbers. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Apr 24, 2025, received Dec 7, 2022, about the electrical system — 4 documents under this number. It names 151 model years across Chevrolet, GMC, Buick and Cadillac (2023–2026). 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.
One page for every brand it was filed under. Each brand’s bulletins: Chevrolet · GMC · Buick · Cadillac.

What owners reported
Source: NHTSA complaint databaseOwners of the 138 model years this bulletin names have filed 8,123 complaints with NHTSA since 2015. 1,631 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 2024 Chevrolet Trax, the 15 owners who gave an odometer reading for Electrical System reported it at a median of 16,400 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
My Traverse prompted me to do an update - I did- and all my cameras stopped working- took to dealership - they tried to do a Manuel update and locked up the whole system- and the USB’s stopped working - 4 weeks later waiting on new system and no answer in site for when parts will be in - contacted GM and they escalated issue - told to be…
2025 Chevrolet Traverse · Electrical System · filed with NHTSA Jul 22, 2025
The entire left portion of the screen became inoperable and remained a black screen despite attempts to reset the system. The left side of the screen contains information such as gear selection, speedometer, lane keep assist, and many other important information. There is no other way to see what speed you are going besides this screen.
2023 Cadillac Lyriq · Electrical System · filed with NHTSA Dec 11, 2024
Vehicle displayed a 'Lithium Ion Battery – Schedule Service Now' warning within approximately one month of delivery. Dealership service records later obtained by our attorney show the identical diagnostic condition was already present and was cleared via a system reset on the date of delivery, October 23, 2025, without disclosure to us.
2026 Cadillac Vistiq · Electrical System · filed with NHTSA Aug 27, 2026
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 22-NA-242 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 22-NA-242 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.
Which vehicles does 22-NA-242 cover?
The manufacturer filed it against 151 model years across 4 brands (Chevrolet, GMC, Buick and Cadillac): 2026 Buick Enclave, 2025 Buick Enclave, 2024 Buick Enclave, 2023 Buick Enclave, 2026 Buick Encore, 2025 Buick Encore and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
