Rearview System Braking problems of the 2022 Chevrolet Silverado 1500

I own a 2022 Chevrolet silverado ltz texas edition with 51,000 miles, equipped with the factory multi-camera system and rear backup camera. The camera images are clear and all cameras function normally, but the forward/reverse guide/trajectory lines no longer appear. When the cameras are activated, a blue hourglass appears in the upper-left corner and the guide lines never load. This is a safety concern because the guide lines help the driver judge the vehicle's path and distance when backing up and maneuvering in tight areas. The loss of this feature reduces the functionality of the factory safety/parking camera system. I took the truck to an authorized gm dealer. They diagnosed a front camera issue and recommended replacing the front camera located under the hood, at a cost of approximately $1,000. I questioned why the camera should be replaced when the camera image itself is clear and functioning normally. The dealer identified dtc b1a68, failure code 0x76, and also provided a report showing numerous additional communication faults. The dealer said I should not be concerned about the other codes. Diagnostic codes reported: b1a68 (0x76), u0101, u0102, u0131, u0140, u0146, u0151, u0155, u0265, u0422, u160f, u1610, u1611. I am concerned that replacing the front camera may not correct the actual cause of the missing guide lines, particularly given the multiple communication faults. This could involve the camera system, software, calibration, can communication network, or another component. I am requesting that NHTSA document and investigate this complaint as a potential safety-related defect affecting the camera/guide-line system on 2022 Chevrolet silverado vehicles. I believe the loss of the factory guide lines is a safety concern and could affect a driver's ability to safely judge the vehicle's path while reversing. The camera also doesn't detect cars or people now. My seat use to vibrate I have the dealer's diagnostic report available as supporting documentation.

Since the truck was updated under the recal n242435631, the camera system guidelines no longer work, which is a feature that was sold as part of the the vehicle. This system no longer works and I fear there are other safety systems that may no longer work. Gm is refusing to fix the software issues that were caused by this recall update.

Since new, this vehicle has had two unresolved safety issues. One of which being the failure of a fmvss 111 required system - rear vision camera. The two defects are: 1. Service 4wd warning message and inability to use 4wd in inclement weather. This has caused safety concerns for my wife and I when traveling in the winter. 2. Failure of the fmvss 111 required rear view camera system when in reverse. The display screen goes blank with an error message intermittently when in reverse.   not being able to see behind the vehicle while in reverse has raised safety concerns by both my wife and I in numerous parking situations. The dealer (al serra Chevrolet grand blanc mi) has attempted warranty repairs on both issues on 4 service visits: delivery date 9/27/2022 1st repair 1/12/2023 2nd repair 11/27/2023 3rd repair 12/19/2023 4th repair 2/27/2023 gm customer assistance case 9-12089878168 2/27/2024 certified letter to gm notifying of intent to file for lemon law relief, final repair attempt. All 4 repair attempts included the 4wd system failure as well as the rear view camera system failure. Many components have been replaced. Along with many reprograming attempts of both systems. Both problems return after the dealer attempts a repair, and have not been successfully repaired to date. The problems first appeared on 1/12/2023. Due to the camera issue being of such a serious safety hazard, we will not drive the vehicle again until repairs are assured. We cannot risk backing into a pedestrian.
