2015 Lexus Rx

I was driving on the highway and suddenly there was a loud explosion and the sound of hundreds of time things or debris hitting my car. Thankfully I did not hit the brakes or lose control of my vehicle, but I easily could have! I then saw little pieces of glass falling off my car from my rear view mirror. I pulled over to find that it was my sunroof. There was no impact from anything, the glass was pointed upward as if the explosion came from inside. This was incredibly scary!

*Three Lexus Dealership Service departments are unable to diagnose the stalling problem so I am unsure what component or system failed or malfunctioned. Yes it is available upon request for inspection. *The stalling happens while engine is cold and at a certain temperature. *The vehicle has been to three dealership service departments and two independant service departments and nobody can find out why it is stalling. *Yes No, No warning lights or messages just stalling. It first appeared a year ago and nobody can detect the problem.

Our car never had any issues, and unexpectedly on Sunday October 10th while my husband was driving it - he heard a loud explosion underneath the car. Immediately there was smoke and then in matter a minutes the car was in flames. My husband had enough time to remove our daughter and the car seat but the car was completely destroyed. We want to know what happened- our car was in incredible condition, low mileage and always kept up on all the maintenance
