“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. First reported to the dealer 08/20/2026. Each time the cameras fail, Apple CarPlay and Bluetooth also fail and remain unusable, leaving no hands-free phone or navigation while driving. …”
