What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 16 complaints with NHTSA since 2015. 5 of them name Electrical System, Power Train — 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Porsche No. 180-23 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. 180-23 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. 180-23 cover?
The manufacturer filed it against 3 model years: 2026 Porsche Cayenne, 2025 Porsche Cayenne, 2024 Porsche Cayenne. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
