GM service campaign N242473580

What it saysCertain vehicles listed above, may have a condition in which the transmission turbine shaft seal was misassembled. NHTSA’s full summary ↓

GM filed this with NHTSA as a service campaign dated Dec 9, 2024, about the power train. It names 4 model years across Chevrolet, GMC and Buick (2024–2025). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

One page for every brand it was filed under. Each brand’s bulletins: Chevrolet · GMC · Buick.

Labour operation and the time the manufacturer allows

OperationDescriptionTime
9107723—9.9 hrs

Read by machine from the document NHTSA serves (6 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.

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.

Model years it names

What owners reported

Source: NHTSA complaint database

Owners of the 4 model years this bulletin names have filed 429 complaints with NHTSA since 2015. 39 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.

The car frequently just slams on the brakes on its own when reversing. Doesn’t matter the speed, and nothing is behind me at all. It also triggers a check engine light with transmission errors if you get a car wash and it is even mildly cold. Transmission errors when it gets too cold or snow in the grill

2025 Buick Enclave · Power Train · filed with NHTSA Apr 20, 2026 · ODI 11732501

The contact owns a 2024 Chevrolet Traverse. The contact stated while driving at various speeds, the check engine warning light illuminated on the instrument panel. The vehicle was taken to several dealers and the contact was informed that the issue was related to the OnStar feature.

2024 Chevrolet Traverse · Power Train · filed with NHTSA Dec 6, 2024 · ODI 11629162

After owning the vehicle for 13 short days, the check engine light came on and a message appeared indicating the vehicle could not be put in reverse due to unsafe vehicle condition. The vehicle just hit 500 miles at this time.

2025 Chevrolet Traverse · Power Train · filed with NHTSA Jul 25, 2025 · ODI 11676112

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 579.5

Is GM N242473580 a recall?

No. A service campaign 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 N242473580 repair free?

A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.

Which vehicles does N242473580 cover?

The manufacturer filed it against 4 model years across 3 brands (Chevrolet, GMC and Buick): 2025 Buick Enclave, 2025 Chevrolet Traverse, 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.
