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.

NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.

Common questions
Source: NHTSA, 49 CFR 579.5Is Porsche GR13D803 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 GR13D803 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 GR13D803 cover?
The manufacturer filed it against 14 model years: 2026 Porsche Cayenne, 2025 Porsche Cayenne, 2024 Porsche Cayenne, 2026 Porsche Macan, 2025 Porsche Macan, 2024 Porsche Macan and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
