What it saysInstructions on advanced technical information for center-locking wheel nut tightening. NHTSA’s full summary ↓
Porsche filed this with NHTSA as a service bulletin dated Apr 23, 2026, received May 7, 2026, about the wheels. It names 15 model years (2016–2026). 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. 1506.2 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. 1506.2 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. 1506.2 cover?
The manufacturer filed it against 15 model years: 2024 Porsche 718, 2026 Porsche 911, 2025 Porsche 911, 2024 Porsche 911, 2023 Porsche 911, 2022 Porsche 911 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
