What owners reported
Source: NHTSA complaint databaseOwners of the 23 model years this bulletin names have filed 68 complaints with NHTSA since 2015. 27 of them name Engine, Electrical 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.
While travelling on the freeway on 7/30/23, I experienced a "low oil pressure, shut down engine immediately" warning. I pulled over to the shoulder and was unable to restart the car. It was towed to Porsche Carlsbad dealership where it is awaiting analysis by Porsche. The car has 4900 miles on it and is under the MFG warranty

While driving 40 miles per hour a sudden explosion happened with no warning. Thought it was the engine due to the smoke coming out of rear of the vehicle but realized that engine was still on and steam was coming out. All coolant drained out of vehicle and on road. Vehicle was towed to a Porsche dealership in Duluth Ga.

The cars auto idle off function that saves fuel by turning the engine off at stop signs and lights in inoperative. I have had it into multiple dealers 4 times since 12/2020 with the complaint. In my opinion there is a temperature sensor that is malfunctioning and not allowing the car to go into the fuel saving mode.

Common questions
Source: NHTSA, 49 CFR 579.5Is Porsche No. 72-17 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 No. 72-17 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 No. 72-17 cover?
The manufacturer filed it against 29 model years: 2025 Porsche 718, 2024 Porsche 718, 2023 Porsche 718, 2022 Porsche 718, 2021 Porsche 718, 2026 Porsche 911 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
