What owners reported
Source: NHTSA complaint databaseOwners of the 2 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.
