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 GM’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 4 model years this bulletin names have filed 2,159 complaints with NHTSA since 2015. 969 of them name Engine — 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 2022 GMC Sierra, the 54 owners who gave an odometer reading for Engine reported it at a median of 47,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
i FEEL IT IS IN THE FUEL MANAGEMENT SYSTEM When driving along every now and then you can feel a vibration like diving on rumble strips. there is no rhyme or reason for it. I had it to the dealer and they told me that was normal, if you don't want it to do it then drive in 9th gear. I'm not going to shift to 9th every time I drive
2022 GMC Sierra · Engine · filed with NHTSA Jan 3, 2023 · ODI 11499958
Vehicle continues to go into limp mode causing us to be stranded on the side of the road. It is related to DEF injection system issues. It sounds like this is a known issue with the software. We purchased the vehicle in August and have been unable to use the truck since purchasing as it continues to leave us stranded.

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 PIE0747A 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 PIE0747A 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 PIE0747A cover?
The manufacturer filed it against 4 model years across 2 brands (Chevrolet and GMC): 2023 Chevrolet Silverado, 2022 Chevrolet Silverado, 2023 GMC Sierra, 2022 GMC Sierra. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
