2021 GMC ACADIA Back Over Prevention Warnings Problems

We purchased the vehicle in March 2021 and within a few weeks, the rear camera started working intermittently. At one point, it displayed a black screen with a red warning triangle. The dealership ultimately replaced the camera and we haven't had the problem since.

Since purchase of this vehicle in Dec 2020, the rear camera vision has been intermittent. I originally thought it to be driver problem however I am now told that there is a module that needs to be replaced and it is not available and possibly not being manufactured at the present time. As a result the entire Camera parking assist system is completely out of service with no information on when the module may be available to repair the issue. I believe this may be a Safety issue as backing up into traffic be it parking lots or roadways, this equipment is an essential addition to safety to other vehicles and pedestrians.

VEHICLE PURCHASED NEW MID-MARCH 2021 AND IN LESS THAN 30 DAYS THE REAR BACK-UP CAMERA STOPPED WORKING INTERMITTENTLY. THIS HAS OCCURRED SEVERAL TIMES AND THE VEHICLE IS CURRENTLY AT THE DEALER BEING DIAGNOSED.
