What the document itself lists

Labour operation and the time the manufacturer allows

OperationDescriptionTime
WHT001163BHexagon-head bolt with inner multiple-tooth head (Duo) M16 x16.5 hrs

Read by machine from the document NHTSA serves (4 pages), read Sep 30, 2026. A part number is shown only where it matches Porsche’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote.

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. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Model years it names

A vehicle page’s bulletin list shows the newest few communications filed against that model year; the count there is every one.

What owners reported

Source: NHTSA complaint database

Owners of the 2 model years this bulletin names have filed 11 complaints with NHTSA since 2015. 1 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.

The contact owned a 2023 Porsche Macan. The contact stated that while driving approximately 40 MPH, the vehicle experienced a loss of automotive power and hesitated to restart as intended. No warning light was illuminated.

2023 Porsche Macan · Engine · filed with NHTSA Oct 14, 2025 · ODI 11693265

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 579.5

Is Porsche WRK2 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 WRK2 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 WRK2 cover?

The manufacturer filed it against 2 model years: 2023 Porsche Cayenne, 2023 Porsche Macan. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
