Automatic Emergency Braking problems of the 2023 Nissan Leaf

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. They also refuse to answer my question about liability if it causes my car to automatically break and cause an accident. This has happened at speeds between 0 and 75 mph.

The car (2023 Nissan Leaf sv plus) was being driven down an urban street during daylight hours and in good weather (no precipitation). The car was being driven in the middle lane, between the right lane and the left turn lane, and at slow speed, as it had been stopped for a stop light. There was a truck parked in the right lane with a "cherry picker" on it that was involved in tree trimming. The truck was not moving. As the Nissan Leaf started to accelerate from the stoplight, the car suddenly applied it's brakes, rapidly slowing the car to a stop, and almost causing the car following to strike the Leaf from behind.
