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 55 model years this bulletin names have filed 620 complaints with NHTSA since 2015. 38 of them name Air Bags — 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.

Over approximately the past month, the leather covering on the dashboard of my 2021 Porsche Cayenne has rapidly begun lifting, buckling, and separating across a substantial portion of the dashboard. The deformation has become increasingly pronounced in a short period of time despite normal use and careful maintenance of the vehicle.

I was parked on surface parking lot with no cars around me, when I put the vehicle in reverse to back out of the parking space, within 2 or 3 seconds the steering wheel airbag exploded without warning. I did not hit anything backing out and there was no collision. I simply put the vehicle in reverse when the airbag exploded.

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 Porsche 74/25 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 74/25 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 Porsche warranty extension on file lists the ones Porsche has filed.
Which vehicles does 74/25 cover?
The manufacturer filed it against 80 model years: 2025 Porsche 718, 2024 Porsche 718, 2023 Porsche 718, 2022 Porsche 718, 2021 Porsche 718, 2020 Porsche 718 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
