2019 BMW X6 ENGINE,FUEL/PROPULSION SYSTEM

While driving to the store my husband notice the vehicle began to over heat. After only driving less than 2 miles the vehicle was parked at my home, it suddenly burst into flames from the engine an hour later. Gratefully, no one was in the vehicle during the incident. We are a family of 5 so that would have been a disgrace. The vehicle was inspected by BMW who claim they can not find cause and deny responsibility. It is unfortunate, our insurance canceled for non-payment a short time before this. Therefore, we have no resource to make us whole again. The vehicle is being temporarily held at BMW of Coconut Creek as this is where it was purchased. Meanwhile, my husband continues to make payments to BMW Finance to protect his credit. Research has shown over hundreds of thousands of like make and models BMW x 6 have been recalled for the same incident from 2012 - 2018 and I can' t help but believe the 2019 should be placed on recall as well before someone is hurt. I can use any advise and guidance on my situation. As I am seeking legal counsel f or the damages.
