Bought a car , went literally up in flames 4 hours later

Edit: recently discovered that the vin # on the KIA sportage IS part of an engine compartment fire recall! Does this information change anything??!!

Yesterday afternoon we went to a dealership that I know and trust . I cannot stress enough that over a 20 year span ive dealt with him , it's a small dealership and he's never done anything shady before.

We signed the paperwork at noon and put half the money down, he was willing to wait for next Friday to receive the other half of the funds.

My husband drove less than a mile up the road and it shut off completely so he took it back they hooked up a code reader and nothing came back . Maybe just a fluke everyone decided. We packed up his drumset and headed out of town to his gig

As were 30 minutes into our trip we hear a pop and I see "something" tumble down the highway behind us and I smell something burning. I told my husband pull over and he does.

We got out of the vehicle and see fluid pouring from underneath the front of the vehicle and I call 911 who instructed us to get away from the car and they would send help . By the time the fure department rolled up with the state trooper it was engulfed in flames and smoke . They then had it towed to a local shop and I called the insurance .

What are my options here? I've researched some recalls on the make and model of the car , am I responsible for the rest of the payment? Is the dealership responsible for replacing the vehicle?Im just at a total loss
