GM bulletin 24-NA-164
What it saysThis bulletin provides information on Wiper Blade Maintenance Tips. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Mar 20, 2025, received Sep 25, 2024, about the visibility/wiper — 3 documents under this number. It names 116 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.

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 106 model years this bulletin names have filed 7,499 complaints with NHTSA since 2015. 224 of them name Visibility/Wiper — 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.
The windshield wipers do not work. When the wipers are turned on, the spray comes on and does not turn off. You are unable to see as the spray keeps spraying the entire time the wipers are on. I took the dealer twice and they have been unable to repair. They now say are waiting for parts. I can't be the only one. This is very concerning.
2024 GMC Hummer EV · Visibility/Wiper · filed with NHTSA Oct 18, 2024
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…
2023 Chevrolet Silverado 2500HD · Visibility/Wiper · filed with NHTSA Nov 30, 2024
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. At approximately 6:24:05 PM, the windshield wipers stopped in the upright position for about 2–3 seconds while the vehicle was in motion, causing a temporary loss of forward visibility.

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 24-NA-164 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 24-NA-164 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 24-NA-164 cover?
The manufacturer filed it against 116 model years across 4 brands (Chevrolet, GMC, Buick and Cadillac): 2025 Buick Enclave, 2024 Buick Enclave, 2023 Buick Enclave, 2025 Buick Encore, 2024 Buick Encore, 2023 Buick Encore and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
