What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 20 complaints with NHTSA since 2015. 4 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.
I was driving on the highway at 60mph on a 4 month old 2025 Porsche Macan Ev 4S. I turned off the AC for both driver and passenger. I suddenly started seeing increasingly larger clouds of black smoke coming out of the passenger side of the cabin, and a clear and increasing smell of something burning.

Common questions
Source: NHTSA, 49 CFR 579.5Is Porsche No. 2604.3 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. 2604.3 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. 2604.3 cover?
The manufacturer filed it against 3 model years: 2026 Porsche Macan, 2025 Porsche Macan, 2024 Porsche Macan. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
