Chevrolet bulletin 22-NA-073
What it saysThis service bulletin provides a procedure to install tie straps to reposition the internal fuel lines away from the ICV Flap internal to the fuel tank to prevent fuel spit back from the filler nozzle. NHTSA’s full summary ↓
Chevrolet filed this with NHTSA as a service bulletin dated Nov 6, 2023, received Apr 6, 2022, about the fuel/propulsion system — 2 documents under this number. It names 9 model years (2016–2024). 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.

Read by machine from the document NHTSA serves (2 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.

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 551 complaints with NHTSA since 2015. 9 of them name Fuel/Propulsion 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.
The rods broke. The lifters are faulty and the power cuts off in the middle of driving. The car was taken back to the dealership and the cam shaft was replaced as well as the rods. However, after getting it back the car looses power and will not accelerate. It is currently in the shop as I type this complaint

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 22-NA-073 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-073 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-073 cover?
The manufacturer filed it against 9 model years: 2024 Chevrolet Camaro, 2023 Chevrolet Camaro, 2022 Chevrolet Camaro, 2021 Chevrolet Camaro, 2020 Chevrolet Camaro, 2019 Chevrolet Camaro and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
