GM bulletin PIP5970A
What it saysThis Preliminary information communicates the restriction of the P02 Engine Control Module NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Oct 25, 2024, about the engine. It names 3 model years across Chevrolet, GMC and Buick (2024–2025). 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.

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.
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 3 model years this bulletin names have filed 243 complaints with NHTSA since 2015. 49 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.

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 · ODI 11618195
Catastrophic engine failure. We were left stranded in while on a trip. No warning lamps. Vehicle was towed and inspected by the Buick dealership service department. Took 3 months to get our vehicle back which had to be transported back to the state in which we live
2025 Buick Enclave · Engine · filed with NHTSA Mar 23, 2026 · ODI 11726348
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 PIP5970A 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 PIP5970A 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 PIP5970A cover?
The manufacturer filed it against 3 model years across 3 brands (Chevrolet, GMC and Buick): 2025 Buick Enclave, 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.
