It names 3 model years (2023–2024).

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 3 complaints with NHTSA since 2015. 1 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.
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 WPR5 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 WPR5 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 WPR5 cover?
The manufacturer filed it against 3 model years: 2024 Porsche 718, 2023 Porsche 718, 2023 Porsche Redundant Cayman GT4. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
