Transmission Fluid Leaking problems of the 2014 Dodge Journey

While driving from from grand rapids and arriving to michigan city, indiana, I hear a noise that mimicked that of a flat tire. I immediately made a right turn into the parking lot to check each one of my tires, but none of them were low or completely deflated. I drove up a bit to park my vehicle, so I could further investigate and it stalled. When I got out of the vehicle, I smelled a light burning smell coming from underneath tbe vehicle and I just let it sit, while calling my insurance company's roadside assistance to obtain support. I had the vehicle towed back to grand rapids costing me $401 because my insurance only paid up to 15 miles for towing and this drive was approximately a 125 mile drive. Due to covid, I had to pay out of pocket for a ride back to grand rapids as well. I had the vehicle towed to the dealership where I purchased the car back in April 2015 and after the delearship checked to diagnose the vehicle, I received a phone call saying it was my all wheel drive powertrain unit/system and it had busted and was leaking fluid. The quote that the gentleman gave was a whopping $2200 and some change. I really thought I remembered purchasing a powertrain warranty, but is there a way to find out for sure if I did? I would appreciate more guidance on this situation because I am out of thousands of dollars and would love to have some financial assistance, if possible. Also, I wanted to initiate a recall for this because if I had been still on the highway driving, this could have turned out way different and I would hate to hear that others may not be as blessed as I was. I do not have my invoice yet because they are working on fixing my car still. I will save it once I do, if needed. Thank you in advance for investigating this safety concern and have a great day!.
