“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.

Dealer confirmation: Four dealer visits for this defect: 08/20/2026, 09/08/2026, 09/30/2026, and 10/14/2026. The dealer reproduced the failure, found fault codes for all four cameras, replaced the front camera, and reworked the passenger door camera wiring harness under Porsche technical instruction TI 9709. The failure continued after repairs. The case was escalated to Porsche field…”
