Read by machine from the document NHTSA serves (4 pages), read Sep 30, 2026. A part number is shown only where it matches Chevrolet’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 9 model years this bulletin names have filed 3,004 complaints with NHTSA since 2015. 1,883 of them name Engine, 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 2016 Chevrolet Malibu, the 173 owners who gave an odometer reading for Engine reported it at a median of 53,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

When the vehicle is stopped at a light, then you begin to ouch on the gas as the light turns green, the car will slow accelerate when pushing on the gas. The crazy part is when I tell Chevrolet about this no one knows what i'm talking about, which is frustrating because it's happening more frequently and it's freaking me out!

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 Chevrolet 21-NA-220 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 21-NA-220 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 21-NA-220 cover?
The manufacturer filed it against 9 model years: 2024 Chevrolet Malibu, 2023 Chevrolet Malibu, 2022 Chevrolet Malibu, 2021 Chevrolet Malibu, 2020 Chevrolet Malibu, 2019 Chevrolet Malibu and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
