Read by machine from the document NHTSA serves (1 page), 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.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 1,992 complaints with NHTSA since 2015. 95 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.
My car is equipped with a forward-facing camera, mounted on the forward area of the interior rearview mirror. Additional cameras are mounted on the front bumper, trunk door, and on the rearview mirrors on each side of the car. Various sensors mounted throughout both bumpers face the front, rear, and each side of the car.

While driving on a public road, the vehicle suddenly shut down and rebooted itself. Motive power was lost during the event. This has happened at least a dozen times during normal driving, including while transporting a child. Video of an occurrence was recorded.
2025 GMC Hummer EV · Fuel/Propulsion System · filed with NHTSA Aug 27, 2026 · ODI 11759966
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 PIP6009B 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 PIP6009B 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 PIP6009B cover?
The manufacturer filed it against 19 model years across 3 brands (Chevrolet, GMC and Cadillac): 2025 Cadillac Escalade, 2025 Cadillac Lyriq, 2024 Cadillac Lyriq, 2023 Cadillac Lyriq, 2025 Cadillac Optiq, 2025 Chevrolet Blazer and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
