2021 Land Rover Discovery Sport SUV 4WD

The vehicle has a transmission problem. The vehicle will shut off at a stop and will come out of gear. I have been sitting at a traffic light and when the light turns green the car will not move (it goes back into neutral). When this happens I have to turn the engine off and restart the car before it will go into drive. When I back out of my driveway onto the main road and then place the vehicle in drive the vehicle will not go into gear leaving me and the car stranded in the road. This vehicle is going to get me injured or killed. Someone is going to hit me because I cannot move out of the way. I have almost been hit numerous times because I cannot get out of the way of oncoming traffic. The car has been back to the manufacturer 3 times now (this time they have had the car 22 days and it is still not repaired). No warning lights have come on before the incident, however the check engine light will appear after the car fails to go into gear.
