Porsche service campaign WPR0

What it saysPorsche intranet posting with information on recoding thermal management control unit NHTSA’s full summary ↓

Porsche filed this with NHTSA as a service campaign dated Aug 20, 2025, received Dec 8, 2023, about the electrical system — 2 documents under this number: No. 177-23 and 1 more. It names 6 model years (2019–2023). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

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.

2019 Porsche Cayenne · Engine · filed with NHTSA Nov 9, 2025 · ODI 11698394

On my 2021 Porsche Cayenne Base, which is equipped with the 3.0L V6 EA839 engine, I brought the vehicle to the dealership for a recall service. During inspection, the dealership found a leaking water pump and quoted $8,500 for repairs. There were no visible signs of a coolant leak on the ground, indicating an internal seal failure.

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 WPR0 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 WPR0 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 WPR0 cover?

The manufacturer filed it against 6 model years: 2023 Porsche Cayenne, 2022 Porsche Cayenne, 2021 Porsche Cayenne, 2020 Porsche Cayenne, 2019 Porsche Cayenne, 2020 Porsche Redundant Cayenne E-Hybrid. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
