Porsche service campaign WSS0
What it saysPorsche intranet posting with information on WSS0 - Workshop Campaign - Check the return line (Porsche Dynamic Chassis Control) and replace it if necessary NHTSA’s full summary ↓
Porsche filed this with NHTSA as a service campaign dated Feb 11, 2026, received Mar 2, 2026, about the suspension — 2 documents under this number: No. WSS0 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Porsche WSS0 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 WSS0 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 WSS0 cover?
The manufacturer filed it against 2 model years: 2026 Porsche 911, 2025 Porsche 911. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
