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. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 4 model years this bulletin names have filed 25 complaints with NHTSA since 2015. 9 of them name Electrical System, Structure, Steering — 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.
2026 Porsche Cayenne Coupe. The surround-view and rear backup camera system repeatedly fails. The screen goes completely black, including when shifting into reverse. The Coupe's shortened, sloped rear window creates major blind spots, so the driver depends on the cameras. When they fail, there is effectively no rear visibility.

Steering Gear. It has been replaced and is not available to inspect. I was unable to turn the steering wheel and had an auto accident as a result. The dealer inspected the vehicle and replaced the steering gear under warranty. It is probable that the defective gear was sent by the dealer to the manufacturer to inspect.

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.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Porsche No. 73-26 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. 73-26 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. 73-26 cover?
The manufacturer filed it against 4 model years: 2026 Porsche Cayenne, 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.
