GM bulletin 24-NA-043
What it saysThis bulletin advises the tech that there are extra characters on the fuel injector and to ignore the last numbers when identifying flow rate. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Aug 9, 2024, received Mar 15, 2024, about the fuel/propulsion system — 2 documents under this number. It names 27 model years across Chevrolet, GMC and Cadillac (2020–2024). 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.
One page for every brand it was filed under. Each brand’s bulletins: Chevrolet · GMC · 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 27 model years this bulletin names have filed 9,336 complaints with NHTSA since 2015. 669 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.
On the 2021 Chevrolet Tahoe, the 26 owners who gave an odometer reading for Fuel/Propulsion System reported it at a median of 40,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
My vehicle lost power while driving on the highway. It was later determined that the fuel pump controller module required replacement. Losing power while driving 65 mph was not enjoyable or safe. The GMC Dealer Service department made the assessment, replaced the module, and the vehicle is now in my possession and functioning as normal.

2023 GMC Yukon · Fuel/Propulsion System · filed with NHTSA Jan 21, 2025 · ODI 11637294
We have owned this 2021 Chevrolet Tahoe for a little less than a year. Since acquiring this vehicle, there have been multiple safety recalls and we have had to get the vehicle serviced 3 times due to electrical issues. Now for the major safety issue, was out of town waiting at a red light in a turning lane.

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-043 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-043 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 24-NA-043 cover?
The manufacturer filed it against 27 model years across 3 brands (Chevrolet, GMC and Cadillac): 2024 Cadillac Escalade, 2023 Cadillac Escalade, 2022 Cadillac Escalade, 2021 Cadillac Escalade, 2020 Cadillac Escalade, 2024 Chevrolet Silverado and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
