Warnings problems of the 2020 Nissan Murano

I've only had the car 3 months and an error code for the forward collision worning light is on. The dealership said it should go off. It never did. It is malfunctioning and it automatically and without notice applied the emergency brake system when it's not needed. It gave me sort of whiplash. It does this often out of no where. This could cause a severe accident.

While parallel parking, we backed into the space and when we put the car into drive, it lurched forward at an incredible speed. We hit and pushed the car parked in front of us, hopped up onto the sidewalk, knocked down a street light, and moved a huge concrete planter. The airbags over the windshield and under the dashboard deployed. The bags under the dash exploded with such force that they injured my husband's legs, and he has been seeing a wound doctor for the past five weeks. The car was towed to a repair shop. I reported the incident to Nissan na; they sent a representative to retrieve information from the edr. Nissan has advised that no mechanical problems were recorded but we are absolutely certain the car malfunctioned. We think it might have been a problem with the cvt.

I was driving 25 mph when the car automatic stopped and applied the automatic emergency brake (aeb) was applied with no obstacles around on a clear sunny day. Purchased the car new with only 3 miles on it. Car came to a complete stop. I am afraid for my safety. Took the car in to dealer and was told nothing is wrong with the car within 1 week it happend again and I was told by the dealer there's nothing wrong with the car.
