Porsche bulletin No. 14-25
What it saysInstallation and conversion instructions for the sports tailpipe - dark bronze. NHTSA’s full summary ↓
Porsche filed this with NHTSA as a service bulletin dated Nov 8, 2025, received Oct 8, 2025, about the wheels — 2 documents under this number. It names 3 model years (2024–2026). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

Common questions
Source: NHTSA, 49 CFR 579.5Is Porsche No. 14-25 a recall?
No. A service bulletin 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 No. 14-25 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Porsche warranty extension on file lists the ones Porsche has filed.
Which vehicles does No. 14-25 cover?
The manufacturer filed it against 3 model years: 2026 Porsche Panamera, 2025 Porsche Panamera, 2024 Porsche Panamera. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
