Transmission Fluid Leaking problems of the 2019 Chevrolet Traverse

2019 Traverse was traveling down road about one mile from starting location car shut off and all dashboard lights came on than noticed smoke from the engine compartment. , flames shorty after. Fd was called and arrived and put out fire. A fluid trail was noticed behind car leading to our house (1 mile away). No issues with the car up to this point. Car was towed and insurance called, notified gm the next day after seeing a recall on leaking transmission (this VIN is not on that list). Gm basically said that once we called the insurance company there is nothing they can do for us. Insurance company (allstate) said they will look into this. Car was a lease and we have no recourse. It seems fishy to me that some models have a recall and this appears to be some kind kind of leak from that area. If gm doesn't care how will they know if this recall needs to involve other models and VIN's of this car. I understand that we leased the car so we lose and can't recoup anything nor will they work with us to lower the cost of a replacement. What if my young children were in the car or my mother in law who has a tough time getting in and out of the car, someone could of been injuried or worst. Someone needs to caer about this. This happened in norwalk CT on east rocks rd 06851. Sunny clear day car was moving forward when it lost power. No recent work on car, no accidente norwalk CT fire incident report 21-001007.
