Blind Spot Detection problems of the 2020 Nissan Rogue

Three separate incidents have happened since leasing this car on Sunday evening on November 1, 2020. The first 2 happened shortly after I left the supermarket, I was pulling out of a parking spot & checked all my mirrors and windows prior to pulling out when I felt in gut that something wasn't right, I covered my brakes while slowly pulling out and asked my son to check out on the right side of the vehicle and there had been a child inches away from my car and I did not see nor was alerted by the vehicle. The second, incident happened when I returned home with the groceries and my children were exiting the vehicle with the groceries, my son then came back to check to see if I needed something else carried upstairs and I did not see my son as I began pulling off, my son children both yelled in voices of distress. . Mom! stop!!! I said, what happened, he said you almost ran me over. Again, the vehicle failed to alert me that someone was in an area that I couldn't see. I couldn't live with myself if I caused bodily injury to my son that could potentially cause grave danger, loss of a limb or death. The third incident happened on Wednesday, November 4, 2020 at approximately 2:46pm, I had been driving cautiously as I do adhering to the speed limit, I noticed a bicyclist pedaling along his way, it seems as if we were heading towards the same direction so I proceeded to drive cautiously as I was approaching an intersection to make a left, I checked all three mirrors and even looked back didn't see him so I began to make a left as I was turning left I could see him in my peripheral vision approaching the cross walk. I immediately stopped my vehicle giving him the right way and thanking god that I did not hit him. Again, my vehicle did not alert me that he was anywhere near my car meanwhile he was extremely close,.
