2023 NISSAN LEAF Forward Collision Avoidance Warnings Problems

My front collision system will sporadically start flashing when there is nothing in front of me. One time a dealer was able to read a code saying that it overheated, and told me that was a known issue with no solution. It was 100F, but I have had the same issue at 35F. The dealership and corporate cannot tell me how the safety system will respond with this error, either disabling my crash prevention system or possibly automatically breaking for no reason. I have taken it to the dealership 4 times. One refused to even try to read the code as it was happening. Another read the code but refused to record it. The other times they kept the car for a total of 8 days and didn’t even look at the component. It seems like they know that this safety issue exists and have no plans to address it....
