Wiper problems of the 2021 Cadillac Escalade

When the vehicle is shifted into reverse, the backup camera intermittently does not display an image. Instead, the screen shows a blue hourglass, leaving me without rear visibility while backing up. This creates a safety risk because I may not be able to see pedestrians, children, vehicles, or objects behind the vehicle, increasing the risk of a crash or injury. Gm has issued service bulletin 23-na-084 for the 2021 Cadillac Escalade, titled “blue hourglass and no gridlines on radio rear view camera display while in reverse. ” the bulletin identifies software anomalies in the video processing module and instructs dealers to reprogram the module. My concern is that this is a safety-related rear visibility failure, not merely a convenience or display issue. I also understand gm/NHTSA campaign 22v709 involved rear-view camera failures on other gm vehicles, including certain Cadillac xt5, Cadillac xt6, and GMC acadia models. Although my Escalade is not included in that recall, the safety consequence is similar: intermittent loss of rear-view camera visibility while reversing. The issue occurs intermittently when shifting into reverse. The vehicle has not been included in a recall for this condition. I respectfully request that NHTSA review whether the 2021 Cadillac Escalade should be included in an existing or expanded safety investigation/recall, or whether a separate defect investigation is warranted for intermittent rear-view camera failures in this model.

- what component or system failed or malfunctioned, and is it available for inspection upon request? the rearview backup camera system seems to be misaligned or improperly calibrated or connecting to the wrong camera when put into reverse. When the vehicle is placed in reverse, the camera image points downward and primarily shows the rear bumper rather than the area behind the vehicle. This significantly limits the rear field of view that the camera is intended to provide. -how was your safety or the safety of others put at risk? because the backup camera view points downward and does not clearly show the area behind the vehicle, it does not show me pedestrians, small children, vehicles or objects directly behind the vehicle when reversing. This creates a risk of backing into a person, vehicle, or object because the driver cannot rely on the camera display to safely check the rear area. - has the problem been reproduced or confirmed by a dealer or independent service center? the dealership did confirm that this is an issue and advised me that they could not figure out what the problem is and sent me on my way without resolution. -has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? the component has been inspected by the dealership. They confirmed it has an issue by comparing the view with another Escalade. -were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no warning lamps, messages, or alerts appeared prior to or during the issue. The backup camera display functions normally but consistently shows an incorrect downward viewing angle that primarily displays the rear bumper instead of the area behind the vehicle.
