- 360-Degree Surround View Camera System Glitches2022-2025
The Grand Wagoneer's 360-degree surround view camera system displays stitching errors, frozen images, distorted perspectives, and intermittent black screens. The system uses four cameras (front, rear, and both side mirrors) composited into a bird's-eye view, and the image processing frequently produces visual artifacts. Individual cameras may fail to initialize, leaving blank quadrants in the surround view. The issue is exacerbated in cold weather and after OTA system updates. The Night Vision camera (if equipped) has separate but similar reliability concerns.
