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.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 3 complaints with NHTSA since 2015. 2 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.
I received delivery of my vehicle this morning and put about 20 miles on it when I received an engine fault error and my vehicle check engine light came on while accelerating from a stop to about 15 mph before the issue occurred. I lost responsiveness and my engine was in “limp mode”.

Common questions
Source: NHTSA, 49 CFR 579.5Is Porsche No. 193-24 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. 193-24 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. 193-24 cover?
The manufacturer filed it against 2 model years: 2023 Porsche 718, 2022 Porsche 718. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
