GM bulletin 22-NA-161
What it saysThis informational bulletin provides information for dealers/technicians on power folding mirrors do not fold at the same speed. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated May 17, 2025, received Aug 30, 2022, about the equipment — 2 documents under this number. It names 38 model years across Chevrolet and GMC (2019–2025). 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.

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 38 model years this bulletin names have filed 8,650 complaints with NHTSA since 2015. 1,487 of them name Electrical System, Visibility/Wiper, Equipment — 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 2019 Chevrolet Silverado, the 72 owners who gave an odometer reading for Electrical System reported it at a median of 11,750 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
This is not a failure, just a poor design for cold temperatures. The windshield wipers are set low on the windshield, below where the defroster can reach. When it is cold/snowing outside, (which it does a lot in the Alaskan interior), the wipers remove the melted water from the windshield and push it down to where the wipers sit in the…

On April 13, 2026, I experienced two safety-related malfunctions while driving my 2025 Chevrolet Silverado 3500 LTZ on a two-lane highway in light rain.

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-161 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-161 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-161 cover?
The manufacturer filed it against 38 model years across 2 brands (Chevrolet and GMC): 2025 Chevrolet Silverado, 2024 Chevrolet Silverado, 2023 Chevrolet Silverado, 2022 Chevrolet Silverado, 2021 Chevrolet Silverado, 2020 Chevrolet Silverado and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
