NHTSA Complaint #11636245 — 2024 BMW X7

My car had an accident and it was hit by another car on the left side, but the camera which was assumed to record the accident, it did not. Fortunately no one get injury. But I have to pay with my insurance. BWM did not admit such fatal error. I talked to them but they said I can sue them.... 1. I went to BMW Darien, the specilist said the camera only worked when being hit by the front, but it is not true, there are 4 cameras which record 360 degree around. 2. I assumed whenever an accident happened, the camera system will be activated, but the BMW people said because the accident was not severe, then the sensors did not work. But when checking my car, the whole left side was damaged, it is not a minor hit. Thus I question how severe would it be sufficient to trigger the system. 3. I have not been to the dealer. 4. The insurance just checked the damage and send me an estimated amount to repair the car. 5. there is no message, or because I was not the driver, I did not know.
