GM filed this with NHTSA as a service bulletin dated Oct 16, 2023, received Nov 15, 2023, about the power train. It names 12 model years across Chevrolet, GMC and Cadillac (2021–2023). 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.

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 12 model years this bulletin names have filed 3,333 complaints with NHTSA since 2015. 617 of them name Power Train — 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 GMC Yukon, the 20 owners who gave an odometer reading for Power Train reported it at a median of 70,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
While driving our 2023 Chevrolet Duramax diesel suburban, I was waiting, at a complete stop, against the median to make a U turn. When the traffic cleared, I began the turn when I suddenly noticed a nearly complete loss of power, hesitancy of engine engagement, and little response to the gas pedal being depressed.

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 PIE0764A 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 PIE0764A 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 PIE0764A cover?
The manufacturer filed it against 12 model years across 3 brands (Chevrolet, GMC and Cadillac): 2023 Cadillac Escalade, 2022 Cadillac Escalade, 2021 Cadillac Escalade, 2023 Chevrolet Suburban, 2022 Chevrolet Suburban, 2021 Chevrolet Suburban and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
