Porsche service campaign WSU3
What it saysPorsche intranet posting with information on WSU3- Workshop Campaign – Replacing air-conditioning compressor shield NHTSA’s full summary ↓
Porsche filed this with NHTSA as a service campaign dated May 20, 2026, received Mar 2, 2026, about the electrical system — 3 documents under this number: No. WSU3 (2 filings) and 1 more. It names 2 model years (2025–2026). 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.

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.

Email me new Porsche bulletins for the Panamera
A weekly email, sent only in a week when Porsche files something new with NHTSA for the model you pick — service bulletins, campaigns, warranty extensions, over-the-air notices, every model year. Nothing else is sent; one-click unsubscribe in every message. Separate from recall alerts.
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 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.
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 WSU3 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 WSU3 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 WSU3 cover?
The manufacturer filed it against 2 model years: 2026 Porsche Panamera, 2025 Porsche Panamera. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
