Quoting the number at a service desk can save a diagnosis.

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 2 model years this bulletin names have filed 198 complaints with NHTSA since 2015. 43 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.
While 2 hours from home driving down the interstate with a full vehicle, the vehicle alarmed and the screen notified "No Oil Pressure, Turn Car Off Now". I pulled over immediately and we had to sit on the edge of the interstate for 45 minutes - a safety hazard for us and the surrounding traffic.
2024 GMC Acadia · Engine · filed with NHTSA Aug 12, 2025
I was driving in the rain and drove through a puddle something I have done many times with previous vehicles. All of a sudden the car stopped accelerating. I would press the gas,the engine would rev, but the car would barely move if at all. I barely made it to a safe location
2024 Chevrolet Traverse · Engine · filed with NHTSA Oct 4, 2024
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 PIE0807A 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 PIE0807A 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 PIE0807A cover?
The manufacturer filed it against 2 model years across 2 brands (Chevrolet and GMC): 2024 Chevrolet Traverse, 2024 GMC Acadia. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
