2025 Nissan Rogue Collision Avoidance Problems

While driving at 45 MPH with my wife in the front passenger seat, on a two lane road (one way each direction) in Wake Forest NC, no cars were in the front or rear of my vehicle , sunny clear weather, the following happened: Driving normally, then all of a sudden, the car proceeds to, what felt like emergency braking and then a split second, the dashboard signals come on , different symbols, then a red image appears on the dashboard (for a split second) then it brakes hard a second time (within a split second) then everything clears and the car proceeds to drive normally. The braking action felt like a severe brake pulsing, then a split second release and then another spilt second brake pulsing and then everything cleared and the car continued to drive normally. The braking was so severe, my wife and I lurched forward towards the windshield, held back by our seat belts. The braking occurred suddenly with nothing near the vehicle. The emergency braking came in the first pulse, then followed by a extremely brief release(split second) then another quick emergency braking action(split second), then multiple lights and warnings quickly appeared on the dash board ending with a split second red symbol (so brief i could not determine any of the warnings or lights). Then the car drove normally after that. If any vehicle had been behind us, a rear accident collision could have taken place. This happened on Saturday, February 14th at approximately 2:30pm on Forestville Road, in Wake Forest, NC. This was an extremely dangerous situation. As this is now a Sunday, the Nissan dealer will be contacted tomorrow and arrangements will be made to bring the vehicle in for an inspection ASAP. I feel the vehicle is unsafe to drive at this point in time.
