What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 24 complaints with NHTSA since 2015. 2 of them name 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.
My 2020 Porsche 911 was two days old when I get a "ignition lock error-service required". The next day the tachometer stopped working. After the dealer fixed the problem, I drove home and park the car for two days. The next day the car would not start.

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 WRC0 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 WRC0 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 WRC0 cover?
The manufacturer filed it against 3 model years: 2022 Porsche 911, 2021 Porsche 911, 2020 Porsche 911. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
