I am writing to raise a serious safety concern regarding my Tesla Model Y Premium AWD 7-seater which was involved in a significant rear-end collision The vehicle sustained substantial impact and has been determined to be a total loss. Given the severity of the collision, I am concerned that none of the airbags deployed. This is a serious safety concern, and I would appreciate a detailed technical explanation rather than a general statement about airbag deployment criteria. Please let me know what information, photographs, police reports, or other documentation you need from me to conduct the investigation
