Computer Failure problems of the 2021 Tesla Model X

We got a 2021 Tesla x for just one month. But the computer has dead three times when I was driving in high way and have my two kids in the back seats. Two out of the three times I had to pull over my car to turn off the engine and turn it on again. One of the times the computer came back again by it self after being dead for couple of minutes. Luckily I did not use self drive mode those drives. Otherwise who knows what the consequences will be. I spoked with a customer service and been told it's a very common occurrence for their car. However this is not common for us. This really affects our safety since the monitor control everything. I have two school age kids and I have drive them to school and after school's activities. So the safety is number one priority concern for us.
