2020 Infiniti QX60 AIR BAGS,FORWARD COLLISION AVOIDANCE

I was involved in a multi-car accident on 11/16/23 wile traveling on the 485 Beltway around Charlotte, NC. It was approximately 6 pm, and completely dark. The traffic was very heavy and traveling at 70 mph ( the speed limit) when a car in front of me was stopped. My 2020 Infinity QX60 did NOT alert me of a potential frontal collision, nor did the car begin braking. I slammed on the brakes, but was unable to keep from hitting the car in front of me. I was then hit in my rear by the car in back of me. NONE of my airbags went off!!! That is inconceivable since my front end collided with the car in front of me AND the car behind me hit my car's rear end. I have a badly bruised sternum and am in a great deal of pain. It hurts all of the time, and is excruciating when I move. The safety systems FAILED. I'm very fortunate that I wasn't more badly injured. My SUV was towed to Larry Campbell's Towing Storage yard, which is located at 7327 Old Statesville Rd. in Charlotte, NC. 28269. ( All 3 cars involved in the accident were towed). The NC Highway Patrol responded to the accident and a report was written. The local report number is 231116167HA.
