GM bulletin 22-NA-235
What it saysThis service bulletin provides repair information to correct a customer concern of Wireless Charging Intermittent When Using iPhone and Samsung Phones at Offset Positions. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Sep 10, 2024, received Dec 6, 2022, about the electrical system — 8 documents under this number. It names 64 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.
One page for every brand it was filed under. Each brand’s bulletins: Chevrolet · GMC · Cadillac.

Read by machine from the document NHTSA serves (8 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 62 model years this bulletin names have filed 6,342 complaints with NHTSA since 2015. 1,161 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.
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.

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-235 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-235 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 22-NA-235 cover?
The manufacturer filed it against 64 model years across 3 brands (Chevrolet, GMC and Cadillac): 2023 Cadillac CT4, 2022 Cadillac CT4, 2023 Cadillac CT5, 2022 Cadillac CT5, 2023 Cadillac Escalade, 2022 Cadillac Escalade and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
