Brake Light On problems of the 2019 Jeep Cherokee

Purchased the vehicle brand new in November 2018 and on several occasions within the past couple months, including today, the red brake light on the dash has spontaneously activated. Most of the time it occurs when I come to a stop light and auto shut off kicks on, however, this issue is very serious since its basically stalling my vehicle while in route, and is very scary since I drive my child around. I've also taken it into the dealership to have it looked at and they are unable to determine the issue, which is extremely disheartening.

While I am in movement driving my vehicle. Without any warning lights popping up in my dashboard. My vehicle suddenly stops. It has happened to me while I was driving in the highway and a semi truck was driving behind me. I hit my brakes fast enough so that the semi truck could react in time, but otherwise I could it have gotten impacted from the back which I am sure. It would it have cause more than just and accident. The date this happened I noticed the car kind of slowed down its velocity fast and dramatically when it stop. It was still running, no smoke or anything coming out of the hood. I did noticed that the heater felt extremely hot more than normal which it also made me panic a bit. She shift gear I wasn't able yo move it at all. They had advised me at the dealership one of the mechanics that sometimes, if this happened; to turn the car off for 10 mins and then turn it back on. I did that, that night and when the car turn back of the stability ligh warning came on, the brakes light came on, the engine ligh came on, the emergency parking light came on, but this this I was was able to move the shift stick but I could only drive forward. I tried to reverse and go back but it wasn't letting me. My sensors were beeping as if I was near or close to hitting something. When my car was the only one in the highway. One of the things that I noticed while seating in my car. This normally happens to my SUV when it's very cold outside. We are talking -4 degrees, but I am surprised because this is a 2019 vehicle that I have and I have only had it for 5 months. I have taken it in for service 4 tmes and they supposedly fix the issue but now it has happened again and I don't feel safe in that vehicle. A vehicle that stops out of nowhere, definitely not safe. I am not only putting myself in danger, but I feel like I am putting everyone around me driving in danger.
