Porsche filed this with NHTSA as a service bulletin dated May 6, 2025, received Mar 6, 2025, about the fuel/propulsion system — 2 documents under this number. It names 10 model years (2016–2025). 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 10 model years this bulletin names have filed 231 complaints with NHTSA since 2015. 19 of them name Fuel/Propulsion 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.
As I was stepping on the accelerator, I heard two pops and somehow the car lost its torque/pull. Check engine light came on. Went to the dealership and they said the high pressure fuel pump is broken and it cracked. There seems to be a recall for 2015 to 2018 models, but not 2020 models. My car only has 13000 miles too.

Common questions
Source: NHTSA, 49 CFR 579.5Is Porsche No. 2505 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. 2505 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. 2505 cover?
The manufacturer filed it against 10 model years: 2025 Porsche Macan, 2024 Porsche Macan, 2023 Porsche Macan, 2022 Porsche Macan, 2021 Porsche Macan, 2020 Porsche Macan and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
