Automatic Emergency Braking problems of the 2019 Infiniti QX60

The car engine suddenly shut off itself while I am driving in the middle of the road. The engine and the collision sensor lights were on, I had to fully stop the car and put it into "p" then restart the engine in order to go again. It was a heavy snowing day, I drove pretty slow about 20- 30 mph. It happened twice that day and one of the times I was stopped at the middle of an intersection. There were no warning lamps or any other symptoms at all, and my car still has fuel which the dealer can prove. It's extremely dangerous because my car just suddenly has to stop especially it was a snowing day. I got the car tolled to an Infiniti dealer the next day, they ran a check and did a test drive (was not snowing the next day) but they couldn't duplicate the problem, so they cannot fix anything. Contacted Infiniti cooperate but they said if the dealer couldn't duplicate the problem, they cannot do anything about it.

The emergency braking system occassionally engages when I am driving. On about four occassions I was driving and the alarm began beeping. The car suddenly began braking. Nothing was directly in front of my vehicle that should have triggered the system. The most recent incident was yesterday, 10/5/21. This afternoon on my way home from work, the following warning appeared after a brief beeping sound, " Feb. Warning. See owners manual. " a symbol was also lit on the dashboard. This warning remained on until I turned my vehicle off once I arrived home. I have not restarted the vehicle to see if the warning reappears. There have also been at least two instances of the rear sensor going off.
