What it saysThis Preliminary information communicates an issue with a SES MIL on and DTC U0139 set in the ECM. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Apr 28, 2023, received May 15, 2023, about the electronic stability control. It names 16 model years across Chevrolet, GMC and Cadillac (2021–2024). 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.

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 16 model years this bulletin names have filed 3,577 complaints with NHTSA since 2015. 1,093 of them name Power Train, 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 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.
The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the vehicle idled and loss power. The contact detected a smoke odor and smoke came inside the vehicle from the rear seats. The service ESC, traction control, forward collision, and engine warning lights were illuminated.
2021 Chevrolet Tahoe · Electrical System · filed with NHTSA Apr 19, 2021
Large fire started at rear of car. Car was parked on driveway and no one was inside. Noticed a burning smell before fire started. Could not locate any smoke. Vehicle rear burst into flames 20 minutes later. Fire department responded quickly and was able to put out the fire before it reached the house. Vehicle is totaled.
2021 GMC Yukon · Electrical System · filed with NHTSA Apr 3, 2023
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 PIT6007 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 PIT6007 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.
Which vehicles does PIT6007 cover?
The manufacturer filed it against 16 model years across 3 brands (Chevrolet, GMC and Cadillac): 2024 Cadillac Escalade, 2023 Cadillac Escalade, 2022 Cadillac Escalade, 2021 Cadillac Escalade, 2024 Chevrolet Suburban, 2023 Chevrolet Suburban and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
