Air Conditioner problems of the 2008 BMW 328

Car caught on fire for unknown reasons. When the car was turned on smoke came out from the air conditioning vents and all doors locked from inside. There were 2 occupants inside that needed assistance to get out while the car was catching fire. The vehicle was parked.

I was pressing on my brake to slow down for a red light and I heard a loud thump from under the hood near the right side. As soon as I got to the stop light, my car started to rattle and vibrate violently. I pulled over and turned off the ignition and started my car and the car wasn't rattling anymore. As soon as I put it into reverse, it started to rattle again and did the same when I put it in drive. The vibrating goes away as soon as I start driving, and is only noticed when idled while in drive or reverse. I had someone come check it out and was told he needed to do further inspection at his shop. He inspected it and told me some bolts broke from the engine mount and the loud thump was from my engine dropping onto the air conditioning.
